3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
19 * wiki: update journal format documentation for lz4 additions
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
27 * Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to
28 schedule events based on time and timezone changes.
30 * add O_TMPFILE support to copy_file_atomic()
32 * nspawn: greater control over selinux label?
34 * the error paths in usbffs_dispatch_ep() leak memory
36 * cgroups: figure out if we can somehow communicate in a cleaner way whether a
37 elogind instance not running in the cgroup root shall or shall not manage the
38 attributes of its top-level cgroup. Currently it assumes it manages all, but
39 then might get EPERM due to permission porblems/userns, which is OK, but this
40 should be revisited to make clearer and also work if the payload elogind runs
41 with full privs and without userns.
43 * cgroups: use inotify to get notified when somebody else modifies cgroups
44 owned by us, then log a friendly warning.
46 * beef up log.c with support for stripping ANSI sequences from strings, so that
47 it is OK to include them in log strings. This would be particularly useful so
48 that our log messages could contain clickable links for example for unit
49 files and suchlike we operate on.
51 * introduce a new SystemCallFilters= group called "@system-service" with a
52 sensible default set for system services, then make use of them in portable
55 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
57 * add attach --enable and attach --now (for attach+enable+start)
59 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
60 selected user is resolvable in the service even if it ships its own /etc/passwd)
62 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
63 other doesn't. What a desaster. Probably to exclude it. Also
64 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
67 * port systemctl, elogind-inhibit, busctl, … over to format-table.[ch]'s table formatters
69 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
71 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
73 * SuccessExitStatus= and friends should probably also accept symbolic exit
74 codes names, i.e. error codes from the list maintained in exit-codes.[ch]
76 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
77 files and directories that are left writable for a unit, and which are
78 removed after the unit goes down again. A bit like --ephemeral for
79 elogind-nspawn but for system services. If used together with RootImage= this
80 should reflink the image file itself.
82 Related: add Ephemeral=<path1> <path2> … which would allow marking
83 specific paths only like this.
85 * add CopyFile= or so as unit file setting that may be used to copy files or
86 directory trees from the host to te services RootImage= and RootDirectory=
87 environment. Which we can use for /etc/machine-id and in particular
88 /etc/resolv.conf. Should be smart and do something useful on read-only
89 images, for example fallback to read-only bind mounting the file instead.
91 * nspawn's console TTY should be allocated from within the container, not
92 mounted in from the outside
94 * show invocation ID in elogind-run output
96 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
98 * tree-wide: ensure we always block the signals we hook into with
99 sd_event_add_signal() first
101 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
102 and so on, which would mean we could report errors and such.
104 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
107 * introduce DefaultSlice= or so in system.conf that allows changing where we
108 place our units by default, i.e. change system.slice to something
109 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
110 be moved somewhere else too. Finally machined and logind should get similar
111 options so that it is possible to move user session scopes and machines to a
112 different slice too by default. Usecase: people who want to put resources on
113 the entire system, with the exception of one specific service. See:
114 https://lists.freedesktop.org/archives/elogind-devel/2018-February/040369.html
116 * maybe rework get_user_creds() to query the user database if $SHELL is used
117 for root, but only then.
119 * be stricter with fds we receive for the fdstore: close them asynchronously
121 * calenderspec: add support for week numbers and day numbers within a
122 year. This would allow us to define "bi-weekly" triggers safely.
124 * add bpf-based implementation of devices cgroup controller logic for compat
125 with cgroupsv2 as supported by newest kernel
127 * introduce sd_id128_get_boot_app_specific() which is like
128 sd_id128_get_machine_app_specific(). After all on long-running systems both
129 IDs have similar properties.
131 * sd-bus: add vtable flag, that may be used to request client creds implicitly
132 and asynchronously before dispatching the operation
134 * make use of ethtool veth peer info in machined, for automatically finding out
135 host-side interface pointing to the container.
137 * add some special mode to LogsDirectory=/StateDirectory=… that allows
138 declaring these directories without necessarily pulling in deps for them, or
139 creating them when starting up. That way, we could declare that
140 systemd-journald writes to /var/log/journal, which could be useful when we
141 doing disk usage calculations and so on.
143 * taint elogind if there are fewer than 65536 users assigned (userns) to the system.
145 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
147 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
148 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
149 as the unit is running or has a job queued.
151 * support projid-based quota in machinectl for containers, and then drop
152 implicit btrfs loopback magic in machined
154 * Add NetworkNamespacePath= to specify a path to a network namespace
156 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
157 introduced) as the RTC epoch, instead of the mtime of NEWS.
159 * add a way to lock down cgroup migration: a boolean, which when set for a unit
160 makes sure the processes in it can never migrate out of it
162 * blog about fd store and restartable services
164 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
166 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
167 magic meaning and is no longer upgraded to something else if set explicitly.
169 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
170 make it lose its identity, i.e. be anonymous. For this we'd have to patch
171 through the whole tree to make all code deal with the case where no machine
174 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
175 suitable for processing with rrdtool. Add bus API to access this data, and
176 possibly implement a CPULoad property based on it.
178 * beef up pam_systemd to take unit file settings such as cgroups properties as
181 * a new "systemd-analyze security" tool outputting a checklist of security
182 features a service does and does not implement
184 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
185 the quota of a the user indicated in User= via unit file settings, like the
186 other resource management concepts. Would mix nicely with DynamicUser=1. Or
187 alternatively, do this with projids, so that we can also cover services
188 running as root. Quota should probably cover all the special dirs such as
189 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
190 is set, plus the whole disk space any image configured with RootImage=.
192 * Introduce "exit" as an EmergencyAction value, and allow to configure a
193 per-unit success/failure exit code to configure. This would be useful for
194 running commands inside of services inside of containers, which could then
195 propagate their failure state all the way up.
197 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
198 disks to see if the UID is already in use.
200 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
201 for all units. It should be both a way to pin units into memory as well as a
202 wait to retrieve their exit data.
204 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
205 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
206 automatically. For example, there could be $RUNTIME_DIRECTORY,
207 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
208 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
209 can adapt to varying directories for these purposes. Special care has to be
210 taken if multiple dirs are configured. Maybe avoid setting the env vars in
213 * expose IO accounting data on the bus, show it in systemd-run --wait and log
214 about it in the resource log message
216 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
217 unit when it is stopped
219 * show whether a service has out-of-date configuration in "systemctl status" by
220 using mtime data of ConfigurationDirectory=.
222 * replace all uses of fgets() + LINE_MAX by read_line()
224 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
225 creates a static, persistent user rather than a dynamic, transient user. We
226 can leverage code from sysusers.d for this.
228 * add some optional flag to ReadWritePaths= and friends, that has the effect
229 that we create the dir in question when the service is started. Example:
231 ReadWritePaths=:/var/lib/foobar
233 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
234 the sd-journal logging socket, and, if the timeout is set to 0, sets
235 O_NONBLOCK on it. That way people can control if and when to block for
238 * hostnamed: populate form factor data from a new hwdb database, so that old
239 yogas can be recognized as "convertible" too, even if they predate the DMI
240 "convertible" form factor
242 * Maybe add a small tool invoked early at boot, that adds in or resizes
243 partitions automatically, to be used when the media used is actually larger
244 than the image written onto it is.
246 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
247 after all. Be strict however, only support the equivalent of nspawn's
248 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
251 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
252 the service cgroup, which is supposed to monitor the service, and when it
253 exits the service is considered failed by its monitor.
255 * track the per-service PAM process properly (i.e. as an additional control
256 process), so that it may be queried on the bus and everything.
258 * add a new "debug" job mode, that is propagated to unit_start() and for
259 services results in two things: we raise SIGSTOP right before invoking
260 execve() and turn off watchdog support. Then, use that to implement
261 "systemd-gdb" for attaching to the start-up of any system service in its
264 * maybe introduce gpt auto discovery for /var/tmp?
266 * maybe add gpt-partition-based user management: each user gets his own
267 LUKS-encrypted GPT partition with a new GPT type. A small nss module
268 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
269 way: the partition index is added as offset to some fixed base uid. User name
270 is stored in GPT partition name. A PAM module authenticates the user via the
271 LUKS partition password. Benefits: strong per-user security, compatibility
272 with stateless/read-only/verity-enabled root. (other idea: do this based on
273 loopback files in /home, without GPT involvement)
275 * gpt-auto logic: introduce support for discovering /var matching an image. For
276 that, use a partition type UUID that is hashed from the OS name (as encoded
277 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
278 field of the root partition. This way can easily support multiple OS
279 installations on the same GPT partition table, without problems with
280 unmatched /var partitions.
282 * gpt-auto logic: related to the above, maybe support a "secondary" root
283 partition, that is mounted to / and is writable, and where the actual root's
284 /usr is mounted into.
286 * gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
288 * drop nss-myhostname in favour of nss-resolve?
290 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
291 then use that for the setting used in user@.service. It should be understood
292 relative to the configured default value.
294 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
296 * enable LockMLOCK to take a percentage value relative to physical memory
298 * Permit masking specific netlink APIs with RestrictAddressFamily=
300 * nspawn: support that /proc, /sys/, /dev are pre-mounted
302 * define gpt header bits to select volatility mode
304 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
306 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
308 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
310 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
312 * ProtectKeyRing= to take keyring calls away
314 * RemoveKeyRing= to remove all keyring entries of the specified user
316 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
317 on PID 1 with the relevant signals, and makes relevant files in /sys and
318 /proc (such as the sysrq stuff) unavailable
320 * DeviceAllow= should also generate seccomp filters for mknod()
322 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
324 * journalctl: make sure -f ends when the container indicated by -M terminates
326 * mount: automatically search for "main" partition of an image has multiple
329 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
332 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
333 find a way to map the User=/Group= of the service to the right name. This way
334 a user/group for a service only has to exist on the host for the right
337 * add bus API for creating unit files in /etc, reusing the code for transient units
339 * add bus API to remove unit files from /etc
341 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
343 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
344 kernel doesn't support linkat() that replaces existing files, currently)
346 * transient units: don't bother with actually setting unit properties, we
347 reload the unit file anyway
349 * journald: sigbus API via a signal-handler safe function that people may call
350 from the SIGBUS handler
352 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
354 * resolved: when routing queries, make sure only look for the *longest* suffix...
356 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
357 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
359 * cache sd_event_now() result from before the first iteration...
361 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
363 * PID1: find a way how we can reload unit file configuration for
364 specific units only, without reloading the whole of systemd
366 * add an explicit parser for LimitRTPRIO= that verifies
367 the specified range and generates sane error messages for incorrect
370 * when we detect that there are waiting jobs but no running jobs, do something
372 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
374 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
376 * there's probably something wrong with having user mounts below /sys,
377 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
378 prefixed with /sys generally special.
379 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
381 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
383 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
385 * add a job mode that will fail if a transaction would mean stopping
386 running units. Use this in timedated to manage the NTP service
388 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
390 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
391 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
393 * The udev blkid built-in should expose a property that reflects
394 whether media was sensed in USB CF/SD card readers. This should then
395 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
396 picked up by systemd unless they contain a medium. This would mirror
397 the behaviour we already have for CD drives.
399 * networkd/udev: implement SR_IOV configuration in .link files:
400 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
402 * hostnamectl: show root image uuid
404 * sysfs set api in libudev is not const
406 * Find a solution for SMACK capabilities stuff:
407 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
409 * "systemctl preset-all" should probably order the unit files it
410 operates on lexicographically before starting to work, in order to
411 ensure deterministic behaviour if two unit files conflict (like DMs
414 * synchronize console access with BSD locks:
415 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
417 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
418 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
420 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
422 * figure out when we can use the coarse timers
424 * add "systemctl start -v foobar.service" that shows logs of a service
425 while the start command runs. This is non-trivial to do without
426 races though, since we should flush out all journal messages before
427 returning from the "systemctl stop".
429 * firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
431 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
433 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
435 * consider showing the unit names during boot up in the status output, not just the unit descriptions
437 * maybe allow timer units with an empty Units= setting, so that they
438 can be used for resuming the system but nothing else.
440 * what to do about udev db binary stability for apps? (raw access is not an option)
442 * man: maybe use the word "inspect" rather than "introspect"?
444 * systemctl: if some operation fails, show log output?
446 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
447 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
449 * exponential backoff in timesyncd when we cannot reach a server
451 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
453 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
455 * systemd.show_status= should probably have a mode where only failed
458 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
459 (throughout the codebase, not only PID1)
463 - service registration
464 - service/domain/types browsing
466 - DNS-SD service registration from socket units
467 - resolved should optionally register additional per-interface LLMNR
468 names, so that for the container case we can establish the same name
469 (maybe "host") for referencing the server, everywhere.
470 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
471 - hook up resolved with machined-based address resolution
473 * refcounting in sd-resolve is borked
475 * Add a new verb "systemctl top"
477 * add new gpt type for btrfs volumes
479 * support empty /etc boots nicely:
480 - nspawn/gpt-generator: introduce new gpt partition type for /usr
482 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
484 * a way for container managers to turn off getty starting via $container_headless= or so...
486 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
488 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
489 they run added to the initial transaction and thus confuse Type=idle.
491 * add bus api to query unit file's X fields.
493 * gpt-auto-generator:
494 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
495 - Make /home automount rather than mount?
497 * add generator that pulls in systemd-network from containers when
498 CAP_NET_ADMIN is set, more than the loopback device is defined, even
499 when it is otherwise off
501 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
503 * implement Distribute= in socket units to allow running multiple
504 service instances processing the listening socket, and open this up
507 * socket units: support creating sockets in different namespace,
508 opening it up for JoinsNamespaceOf=. This would require to fork off
509 a tiny process that joins the namespace and creates/binds the socket
510 and passes this back to PID1 via SCM_RIGHTS. This also could be used
511 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
513 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
514 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
515 should SIGSTOP all unit processes in a loop until all processes of
516 it are fully stopped. This can later be used for app management by
517 desktop UIs such as gnome-shell to freeze apps that are not visible
518 on screen, not unlike how job control works on the shell
521 - implement per-slice CPUFairScheduling=1 switch
522 - handle jointly mounted controllers correctly
523 - introduce high-level settings for RT budget, swappiness
524 - how to reset dynamically changed unit cgroup attributes sanely?
525 - when reloading configuration, apply new cgroup configuration
526 - when recursively showing the cgroup hierarchy, optionally also show
527 the hierarchies of child processes
530 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
532 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
534 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
536 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
538 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
540 * rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
542 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
544 * If we try to find a unit via a dangling symlink, generate a clean
545 error. Currently, we just ignore it and read the unit from the search
548 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
550 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
552 * load .d/*.conf dropins for device units
554 * allow implementation of InaccessibleDirectories=/ plus
555 ReadOnlyDirectories=... for whitelisting files for a service.
559 - GetAllProperties() on a non-existing object does not result in a failure currently
560 - port to sd-resolve for connecting to TCP dbus servers
561 - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
562 - see if we can drop more message validation on the sending side
563 - add API to clone sd_bus_message objects
564 - longer term: priority inheritance
566 - NameLost/NameAcquired obsolete
569 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
572 - allow multiple signal handlers per signal?
573 - document chaining of signal handler for SIGCHLD and child handlers
574 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
575 - generate a failure of a default event loop is executed out-of-thread
576 - maybe add support for inotify events (which we can do safely now, with O_PATH)
578 * investigate endianness issues of UUID vs. GUID
580 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
581 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
583 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
585 * add a pam module that on password changes updates any LUKS slot where the password matches
587 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
590 - add unit tests for config_parse_device_allow()
592 * seems that when we follow symlinks to units we prefer the symlink
593 destination path over /etc and /usr. We should not do that. Instead
594 /etc should always override /run+/usr and also any symlink
597 * when isolating, try to figure out a way how we implicitly can order
598 all units we stop before the isolating unit...
600 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
602 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
603 that the boot loader should be installed to the ESP. Define a way
604 how an installer can figure out whether a BLS compliant boot loader
607 * think about requeuing jobs when daemon-reload is issued? usecase:
608 the initrd issues a reload after fstab from the host is accessible
609 and we might want to requeue the mounts local-fs acquired through
612 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
614 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
616 * shutdown logging: store to EFI var, and store to USB stick?
618 * merge unit_kill_common() and unit_kill_context()
620 * introduce ExecCondition= in services
623 - honor language efi variables for default language selection (if there are any?)
624 - honor timezone efi variables for default timezone selection (if there are any?)
625 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
627 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
629 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
631 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
634 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
635 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
636 - logind: wakelock/opportunistic suspend support
637 - Add pretty name for seats in logind
638 - logind: allow showing logout dialog from system?
639 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
640 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
641 - if pam_systemd is invoked by su from a process that is outside of a
642 any session we should probably just become a NOP, since that's
643 usually not a real user session but just some system code that just
645 - logind: make the Suspend()/Hibernate() bus calls wait for the for
646 the job to be completed. before returning, so that clients can wait
647 for "systemctl suspend" to finish to know when the suspending is
649 - logind: when the power button is pressed short, just popup a
650 logout dialog. If it is pressed for 1s, do the usual
651 shutdown. Inspiration are Macs here.
652 - expose "Locked" property on logind sesison objects
653 - maybe allow configuration of the StopTimeout for session scopes
654 - rename session scope so that it includes the UID. THat way
655 the session scope can be arranged freely in slices and we don't have
656 make assumptions about their slice anymore.
657 - follow PropertiesChanged state more closely, to deal with quick logouts and
660 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
663 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
664 - import and delete pstore filesystem content at startup
665 - journald: also get thread ID from client, plus thread name
666 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
667 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
668 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
669 - declare the local journal protocol stable in the wiki interface chart
670 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
671 - journald: when dropping msgs due to ratelimit make sure to write
672 "dropped %u messages" not only when we are about to print the next
673 message that works, but alraedy after a short tiemout
674 - check if we can make journalctl by default use --follow mode inside of less if called without args?
675 - maybe add API to send pairs of iovecs via sd_journal_send
676 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
677 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
678 and !FOOBAR for events without FOOBAR.
679 - journal: store timestamp of journal_file_set_offline() int he header,
680 so it is possible to display when the file was last synced.
681 - journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
682 - journal: find a way to allow dropping history early, based on priority, other rules
683 - journal: When used on NFS, check payload hashes
684 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
685 - refuse taking lower-case variable names in sd_journal_send() and friends.
686 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
687 - journal: deal nicely with byte-by-byte copied files, especially regards header
688 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
689 - Replace utmp, wtmp, btmp, and lastlog completely with journal
690 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
691 - when a kernel driver logs in a tight loop, we should ratelimit that too.
692 - journald: optionally, log debug messages to /run but everything else to /var
693 - journald: when we drop syslog messages because the syslog socket is
694 full, make sure to write how many messages are lost as first thing
695 to syslog when it works again.
696 - change systemd-journal-flush into a service that stays around during
697 boot, and causes the journal to be moved back to /run on shutdown,
698 so that we do not keep /var busy. This needs to happen synchronously,
699 hence doing this via signals is not going to work.
700 - optionally support running journald from the command line for testing purposes in external projects
701 - journald: allow per-priority and per-service retention times when rotating/vacuuming
702 - journald: make use of uid-range.h to managed uid ranges to split
704 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
705 - improve journalctl performance by loading journal files
706 lazily. Encode just enough information in the file name, so that we
707 do not have to open it to know that it is not interesting for us, for
708 the most common operations.
709 - man: document that corrupted journal files is nothing to act on
710 - rework journald sigbus stuff to use mutex
711 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
712 services that run under their own user ids, and use User= (but only
713 in a world where userns is ubiquitous since otherwise we cannot
714 invoke those daemons on the host AND in a container anymore). Also,
715 if LimitNPROC= is used without User= we should warn and refuse
717 - journalctl --verify: don't show files that are currently being
718 written to as FAIL, but instead show that their are being written to.
719 - add journalctl -H that talks via ssh to a remote peer and passes through
721 - add a version of --merge which also merges /var/log/journal/remote
722 - journalctl: -m should access container journals directly by enumerating
723 them via machined, and also watch containers coming and going.
724 Benefit: nspawn --ephemeral would start working nicely with the journal.
725 - assign MESSAGE_ID to log messages about failed services
727 * add a test if all entries in the catalog are properly formatted.
728 (Adding dashes in a catalog entry currently results in the catalog entry
729 being silently skipped. journalctl --update-catalog must warn about this,
730 and we should also have a unit test to check that all our message are OK.)
733 - document that deps in [Unit] sections ignore Alias= fields in
734 [Install] units of other units, unless those units are disabled
735 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
736 - document that service reload may be implemented as service reexec
737 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
738 - document systemd-journal-flush.service properly
739 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
740 - man: document the very specific env the shutdown drop-in tools live in
741 - man: add more examples to man pages
742 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
745 - add systemctl switch to dump transaction without executing it
746 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
747 - "systemctl disable" on a static unit prints no message and does
748 nothing. "systemctl enable" does nothing, and gives a bad message
749 about it. Should fix both to print nice actionable messages.
750 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
751 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
752 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
753 - systemctl: "Journal has been rotated since unit was started." message is misleading
754 - systemctl status output should include list of triggering units and their status
757 - "systemctl mask" should find all names by which a unit is accessible
758 (i.e. by scanning for symlinks to it) and link them all to /dev/null
761 - timer units should get the ability to trigger when:
762 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
765 - Modulate timer frequency based on battery state
767 * add libsystemd-password or so to query passwords during boot using the password agent logic
769 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
771 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
773 * make repeated alt-ctrl-del presses printing a dump
775 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
777 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
780 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
781 with seccomp. That should provide us with a useful log buffer that
782 systemd can log to during early boot, and disconnect container logs
783 from the kernel's logs.
784 - as soon as networkd has a bus interface, hook up --network-interface=,
785 --network-bridge= with networkd, to trigger netdev creation should an
787 - a nice way to boot up without machine id set, so that it is set at boot
788 automatically for supporting --ephemeral. Maybe hash the host machine id
789 together with the machine name to generate the machine id for the container
790 - fix logic always print a final newline on output.
791 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
792 - should optionally support receiving WATCHDOG=1 messages from its payload
794 - optionally automatically add FORWARD rules to iptables whenever nspawn is
795 running, remove them when shut down.
796 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
800 - refuse mounting over a mount point
801 - automatically discover .roothash files in dissect, similarly to nspawn
804 - add an API so that libvirt-lxc can inform us about network interfaces being
805 removed or added to an existing machine
806 - "machinectl migrate" or similar to copy a container from or to a
807 difference host, via ssh
808 - introduce systemd-nspawn-ephemeral@.service, and hook it into
809 "machinectl start" with a new --ephemeral switch
810 - "machinectl status" should also show internal logs of the container in
812 - "machinectl list-images" should show os-release data, as well as
813 machine-info data (including deployment level)
814 - "machinectl history"
816 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
817 shell in it, and marks it read-only after use
820 - generate a nice warning if mkfs.btrfs is missing
823 - cryptsetup-generator: allow specification of passwords in crypttab itself
824 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
826 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
827 https://bugs.freedesktop.org/show_bug.cgi?id=54712
829 * add a dependency on standard-conf.xml and other included files to man pages
831 * MountFlags=shared acts as MountFlags=slave right now.
833 * properly handle loop back mounts via fstab, especially regards to fsck/passno
835 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
840 - add trigger --subsystem-match=usb/usb_device device
841 - reimport udev db after MOVE events for devices without dev_t
843 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
845 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
848 - save coredump in Windows/Mozilla minidump format
849 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
851 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
853 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
855 * be able to specify a forced restart of service A where service B depends on, in case B
856 needs to be auto-respawned?
859 - apply "x" on "D" too (see patch from William Douglas)
861 - instead of ignoring unknown fields, reject them.
862 - creating new directories/subvolumes/fifos/device nodes
863 should not follow symlinks. None of the other adjustment or creation
864 calls follow symlinks.
866 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
868 * verify that the AF_UNIX sockets of a service in the fs still exist
869 when we start a service in order to avoid confusion when a user
870 assumes starting a service is enough to make it accessible
872 * Make it possible to set the keymap independently from the font on
873 the kernel cmdline. Right now setting one resets also the other.
875 * and a dbus call to generate target from current state
877 * write blog stories about:
878 - hwdb: what belongs into it, lsusb
879 - enabling dbus services
880 - how to make changes to sysctl and sysfs attributes
882 - how to pass throw-away units to systemd, or dynamically change properties of existing units
883 - testing with Harald's awesome test kit
885 - how to develop against journal browsing APIs
886 - the journal HTTP iface
887 - non-cgroup resource management
888 - dynamic resource management with cgroups
889 - refreshed, longer missions statement
890 - calendar time events
891 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
892 - how to create your own target
893 - instantiated apache, dovecot and so on
894 - hooking a script into various stages of shutdown/rearly booot
896 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
898 * dot output for --test showing the 'initial transaction'
901 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
902 log both units as UNIT=, so that journalctl -u triggers on both.
903 - generate better errors when people try to set transient properties
904 that are not supported...
905 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
906 - maybe introduce WantsMountsFor=? Usecase:
907 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
908 - recreate systemd's D-Bus private socket file on SIGUSR2
909 - move PAM code into its own binary
910 - when we automatically restart a service, ensure we restart its rdeps, too.
911 - hide PAM options in fragment parser when compile time disabled
912 - Support --test based on current system state
913 - If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
914 - after deserializing sockets in socket.c we should reapply sockopts and things
915 - drop PID 1 reloading, only do reexecing (difficult: Reload()
916 currently is properly synchronous, Reexec() is weird, because we
917 cannot delay the response properly until we are back, so instead of
918 being properly synchronous we just keep open the fd and close it
919 when done. That means clients do not get a successful method reply,
920 but much rather a disconnect on success.
921 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
922 - when a bus name of a service disappears from the bus make sure to queue further activation requests
925 - allow port=0 in .socket units
926 - maybe introduce ExecRestartPre=
927 - add ReloadSignal= for configuring a reload signal to use
928 - implement Register= switch in .socket units to enable registration
929 in Avahi, RPC and other socket registration services.
930 - allow Type=simple with PIDFile=
931 https://bugzilla.redhat.com/show_bug.cgi?id=723942
932 - allow writing multiple conditions in unit files on one line
933 - load-fragment: when loading a unit file via a chain of symlinks
934 verify that it is not masked via any of the names traversed.
935 - introduce Type=pid-file
936 - introduce mix of BindTo and Requisite
937 - add a concept of RemainAfterExit= to scope units
938 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
941 - Make sure ID_PATH is always exported and complete for
942 network devices where possible, so we can safely rely
944 - check MTUBytes parsing (expecting size_t but we are using unsigned)
947 - add support for more attribute types
948 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
951 - add more keys to [Route] and [Address] sections
952 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
953 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
954 - add reduced [Link] support to .network files
955 - add Scope= parsing option for [Network]
956 - properly handle routerless dhcp leases
957 - work with non-Ethernet devices
958 - add support for more bond options
959 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
960 - the DHCP lease data (such as NTP/DNS) is still made available when
961 a carrier is lost on a link. It should be removed instantly.
962 - expose in the API the following bits:
963 - option 15, domain name and/or option 119, search list
964 - option 12, host name and/or option 81, fqdn
965 - option 123, 144, geolocation
966 - option 252, configure http proxy (PAC/wpad)
967 - provide a way to define a per-network interface default metric value
968 for all routes to it. possibly a second default for DHCP routes.
969 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
970 support Name=foo*|bar*|baz ?
971 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
972 - allow DUID/IAID to be customized, see issue #394.
973 - whenever uplink info changes, make DHCP server send out FORCERENEW
975 * networkd-wait-online:
976 - make operstates to wait for configurable?
979 - figure out how much we can increase Maximum Message Size
982 - add functions to set previously stored IPv6 addresses on startup and get
983 them at shutdown; store them in client->ia_na
984 - write more test cases
985 - implement reconfigure support, see 5.3., 15.11. and 22.20.
986 - implement support for temporary adressess (IA_TA)
987 - implement dhcpv6 authentication
988 - investigate the usefulness of Confirm messages; i.e. are there any
989 situations where the link changes without any loss in carrier detection
991 - some servers don't do rapid commit without a filled in IA_NA, verify
998 - natively watch for dbus-*.service symlinks (PENDING)
999 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1001 * fix alsa mixer restore to not print error when no config is stored
1003 * make cryptsetup lower --iter-time
1005 * patch kernel for xattr support in /dev, /proc/, /sys?
1007 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1009 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
1011 * /usr/bin/service should actually show the new command line
1013 * fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
1015 * fedora: F20: go timer units all the way, leave cron.daily for cron
1017 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1019 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1021 * register catalog database signature as file magic
1023 * zsh shell completion:
1024 - <command> <verb> -<TAB> should complete options, but currently does not
1025 - systemctl add-wants,add-requires
1030 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1032 * check for strerror(r) instead of strerror(-r)
1036 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1038 * use secure_getenv() instead of getenv() where appropriate
1040 * link up selected blog stories from man pages and unit files Documentation= fields
