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 proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
28 and so on, which would mean we could report errors and such.
30 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
33 * introduce DefaultSlice= or so in system.conf that allows changing where we
34 place our units by default, i.e. change system.slice to something
35 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
36 be moved somewhere else too. Finally machined and logind should get similar
37 options so that it is possible to move user session scopes and machines to a
38 different slice too by default. Usecase: people who want to put resources on
39 the entire system, with the exception of one specific service. See:
40 https://lists.freedesktop.org/archives/elogind-devel/2018-February/040369.html
42 * maybe rework get_user_creds() to query the user database if $SHELL is used
43 for root, but only then.
45 * be stricter with fds we receive for the fdstore: close them asynchronously
47 * calenderspec: add support for week numbers and day numbers within a
48 year. This would allow us to define "bi-weekly" triggers safely.
50 * add bpf-based implementation of devices cgroup controller logic for compat
51 with cgroupsv2 as supported by newest kernel
53 * introduce sd_id128_get_boot_app_specific() which is like
54 sd_id128_get_machine_app_specific(). After all on long-running systems both
55 IDs have similar properties.
57 * sd-bus: add vtable flag, that may be used to request client creds implicitly
58 and asynchronously before dispatching the operation
60 * make use of ethtool veth peer info in machined, for automatically finding out
61 host-side interface pointing to the container.
63 * add some special mode to LogsDirectory=/StateDirectory=… that allows
64 declaring these directories without necessarily pulling in deps for them, or
65 creating them when starting up. That way, we could declare that
66 systemd-journald writes to /var/log/journal, which could be useful when we
67 doing disk usage calculations and so on.
69 * taint elogind if there are fewer than 65536 users assigned (userns) to the system.
71 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
73 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
74 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
75 as the unit is running or has a job queued.
77 * support projid-based quota in machinectl for containers, and then drop
78 implicit btrfs loopback magic in machined
80 * Add NetworkNamespacePath= to specify a path to a network namespace
82 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
83 introduced) as the RTC epoch, instead of the mtime of NEWS.
85 * add a way to lock down cgroup migration: a boolean, which when set for a unit
86 makes sure the processes in it can never migrate out of it
88 * blog about fd store and restartable services
90 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
92 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
93 magic meaning and is no longer upgraded to something else if set explicitly.
95 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
96 make it lose its identity, i.e. be anonymous. For this we'd have to patch
97 through the whole tree to make all code deal with the case where no machine
100 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
101 suitable for processing with rrdtool. Add bus API to access this data, and
102 possibly implement a CPULoad property based on it.
104 * beef up pam_systemd to take unit file settings such as cgroups properties as
107 * a new "systemd-analyze security" tool outputting a checklist of security
108 features a service does and does not implement
110 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
111 the quota of a the user indicated in User= via unit file settings, like the
112 other resource management concepts. Would mix nicely with DynamicUser=1. Or
113 alternatively, do this with projids, so that we can also cover services
114 running as root. Quota should probably cover all the special dirs such as
115 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
116 is set, plus the whole disk space any image configured with RootImage=.
118 * Introduce "exit" as an EmergencyAction value, and allow to configure a
119 per-unit success/failure exit code to configure. This would be useful for
120 running commands inside of services inside of containers, which could then
121 propagate their failure state all the way up.
123 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
124 disks to see if the UID is already in use.
126 * add dissect_image_warn() as a wrapper around dissect_image() that prints
127 friendly log messages for the returned errors, so that we don't have to
128 duplicate that in nspawn, elogind-dissect and PID 1.
130 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
131 for all units. It should be both a way to pin units into memory as well as a
132 wait to retrieve their exit data.
134 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
135 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
136 automatically. For example, there could be $RUNTIME_DIRECTORY,
137 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
138 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
139 can adapt to varying directories for these purposes. Special care has to be
140 taken if multiple dirs are configured. Maybe avoid setting the env vars in
143 * expose IO accounting data on the bus, show it in systemd-run --wait and log
144 about it in the resource log message
146 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
147 unit when it is stopped
149 * show whether a service has out-of-date configuration in "systemctl status" by
150 using mtime data of ConfigurationDirectory=.
152 * replace all uses of fgets() + LINE_MAX by read_line()
154 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
155 creates a static, persistent user rather than a dynamic, transient user. We
156 can leverage code from sysusers.d for this.
158 * add some optional flag to ReadWritePaths= and friends, that has the effect
159 that we create the dir in question when the service is started. Example:
161 ReadWritePaths=:/var/lib/foobar
163 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
164 the sd-journal logging socket, and, if the timeout is set to 0, sets
165 O_NONBLOCK on it. That way people can control if and when to block for
168 * hostnamed: populate form factor data from a new hwdb database, so that old
169 yogas can be recognized as "convertible" too, even if they predate the DMI
170 "convertible" form factor
172 * Maybe add a small tool invoked early at boot, that adds in or resizes
173 partitions automatically, to be used when the media used is actually larger
174 than the image written onto it is.
176 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
177 after all. Be strict however, only support the equivalent of nspawn's
178 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
181 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
182 the service cgroup, which is supposed to monitor the service, and when it
183 exits the service is considered failed by its monitor.
185 * track the per-service PAM process properly (i.e. as an additional control
186 process), so that it may be queried on the bus and everything.
188 * add a new "debug" job mode, that is propagated to unit_start() and for
189 services results in two things: we raise SIGSTOP right before invoking
190 execve() and turn off watchdog support. Then, use that to implement
191 "systemd-gdb" for attaching to the start-up of any system service in its
194 * maybe introduce gpt auto discovery for /var/tmp?
196 * maybe add gpt-partition-based user management: each user gets his own
197 LUKS-encrypted GPT partition with a new GPT type. A small nss module
198 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
199 way: the partition index is added as offset to some fixed base uid. User name
200 is stored in GPT partition name. A PAM module authenticates the user via the
201 LUKS partition password. Benefits: strong per-user security, compatibility
202 with stateless/read-only/verity-enabled root. (other idea: do this based on
203 loopback files in /home, without GPT involvement)
205 * gpt-auto logic: introduce support for discovering /var matching an image. For
206 that, use a partition type UUID that is hashed from the OS name (as encoded
207 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
208 field of the root partition. This way can easily support multiple OS
209 installations on the same GPT partition table, without problems with
210 unmatched /var partitions.
212 * gpt-auto logic: related to the above, maybe support a "secondary" root
213 partition, that is mounted to / and is writable, and where the actual root's
214 /usr is mounted into.
216 * 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
218 * drop nss-myhostname in favour of nss-resolve?
220 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
221 then use that for the setting used in user@.service. It should be understood
222 relative to the configured default value.
224 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
226 * enable LockMLOCK to take a percentage value relative to physical memory
228 * Permit masking specific netlink APIs with RestrictAddressFamily=
230 * nspawn: support that /proc, /sys/, /dev are pre-mounted
232 * define gpt header bits to select volatility mode
234 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
236 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
238 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
240 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
242 * ProtectKeyRing= to take keyring calls away
244 * RemoveKeyRing= to remove all keyring entries of the specified user
246 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
247 on PID 1 with the relevant signals, and makes relevant files in /sys and
248 /proc (such as the sysrq stuff) unavailable
250 * DeviceAllow= should also generate seccomp filters for mknod()
252 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
254 * journalctl: make sure -f ends when the container indicated by -M terminates
256 * mount: automatically search for "main" partition of an image has multiple
259 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
262 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
263 find a way to map the User=/Group= of the service to the right name. This way
264 a user/group for a service only has to exist on the host for the right
267 * add bus API for creating unit files in /etc, reusing the code for transient units
269 * add bus API to remove unit files from /etc
271 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
273 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
274 kernel doesn't support linkat() that replaces existing files, currently)
276 * check if DeviceAllow= should split first, resolve specifiers later
278 * transient units: don't bother with actually setting unit properties, we
279 reload the unit file anyway
281 * journald: sigbus API via a signal-handler safe function that people may call
282 from the SIGBUS handler
284 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
286 * resolved: when routing queries, make sure only look for the *longest* suffix...
288 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
289 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
291 * cache sd_event_now() result from before the first iteration...
293 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
295 * PID1: find a way how we can reload unit file configuration for
296 specific units only, without reloading the whole of systemd
298 * add an explicit parser for LimitRTPRIO= that verifies
299 the specified range and generates sane error messages for incorrect
302 * when we detect that there are waiting jobs but no running jobs, do something
304 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
306 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
308 * there's probably something wrong with having user mounts below /sys,
309 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
310 prefixed with /sys generally special.
311 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
313 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
315 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
317 * add a job mode that will fail if a transaction would mean stopping
318 running units. Use this in timedated to manage the NTP service
320 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
322 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
323 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
325 * The udev blkid built-in should expose a property that reflects
326 whether media was sensed in USB CF/SD card readers. This should then
327 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
328 picked up by systemd unless they contain a medium. This would mirror
329 the behaviour we already have for CD drives.
331 * networkd/udev: implement SR_IOV configuration in .link files:
332 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
334 * hostnamectl: show root image uuid
336 * sysfs set api in libudev is not const
338 * Find a solution for SMACK capabilities stuff:
339 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
341 * "systemctl preset-all" should probably order the unit files it
342 operates on lexicographically before starting to work, in order to
343 ensure deterministic behaviour if two unit files conflict (like DMs
346 * synchronize console access with BSD locks:
347 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
349 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
350 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
352 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
354 * figure out when we can use the coarse timers
356 * add "systemctl start -v foobar.service" that shows logs of a service
357 while the start command runs. This is non-trivial to do without
358 races though, since we should flush out all journal messages before
359 returning from the "systemctl stop".
361 * 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
363 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
365 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
367 * consider showing the unit names during boot up in the status output, not just the unit descriptions
369 * maybe allow timer units with an empty Units= setting, so that they
370 can be used for resuming the system but nothing else.
372 * what to do about udev db binary stability for apps? (raw access is not an option)
374 * man: maybe use the word "inspect" rather than "introspect"?
376 * systemctl: if some operation fails, show log output?
378 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
379 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
381 * exponential backoff in timesyncd when we cannot reach a server
383 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
385 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
387 * systemd.show_status= should probably have a mode where only failed
390 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
391 (throughout the codebase, not only PID1)
395 - service registration
396 - service/domain/types browsing
398 - DNS-SD service registration from socket units
399 - resolved should optionally register additional per-interface LLMNR
400 names, so that for the container case we can establish the same name
401 (maybe "host") for referencing the server, everywhere.
402 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
403 - hook up resolved with machined-based address resolution
405 * refcounting in sd-resolve is borked
407 * Add a new verb "systemctl top"
409 * add new gpt type for btrfs volumes
411 * support empty /etc boots nicely:
412 - nspawn/gpt-generator: introduce new gpt partition type for /usr
414 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
416 * a way for container managers to turn off getty starting via $container_headless= or so...
418 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
420 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
421 they run added to the initial transaction and thus confuse Type=idle.
423 * add bus api to query unit file's X fields.
425 * gpt-auto-generator:
426 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
427 - Make /home automount rather than mount?
429 * add generator that pulls in systemd-network from containers when
430 CAP_NET_ADMIN is set, more than the loopback device is defined, even
431 when it is otherwise off
433 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
435 * implement Distribute= in socket units to allow running multiple
436 service instances processing the listening socket, and open this up
439 * socket units: support creating sockets in different namespace,
440 opening it up for JoinsNamespaceOf=. This would require to fork off
441 a tiny process that joins the namespace and creates/binds the socket
442 and passes this back to PID1 via SCM_RIGHTS. This also could be used
443 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
445 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
446 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
447 should SIGSTOP all unit processes in a loop until all processes of
448 it are fully stopped. This can later be used for app management by
449 desktop UIs such as gnome-shell to freeze apps that are not visible
450 on screen, not unlike how job control works on the shell
453 - implement per-slice CPUFairScheduling=1 switch
454 - handle jointly mounted controllers correctly
455 - introduce high-level settings for RT budget, swappiness
456 - how to reset dynamically changed unit cgroup attributes sanely?
457 - when reloading configuration, apply new cgroup configuration
458 - when recursively showing the cgroup hierarchy, optionally also show
459 the hierarchies of child processes
462 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
463 - ensure scope units may be started only a single time
465 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
467 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
469 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
471 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
473 * 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
475 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
477 * If we try to find a unit via a dangling symlink, generate a clean
478 error. Currently, we just ignore it and read the unit from the search
481 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
483 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
485 * load .d/*.conf dropins for device units
487 * allow implementation of InaccessibleDirectories=/ plus
488 ReadOnlyDirectories=... for whitelisting files for a service.
492 - GetAllProperties() on a non-existing object does not result in a failure currently
493 - port to sd-resolve for connecting to TCP dbus servers
494 - 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
495 - see if we can drop more message validation on the sending side
496 - add API to clone sd_bus_message objects
497 - longer term: priority inheritance
499 - NameLost/NameAcquired obsolete
502 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
505 - allow multiple signal handlers per signal?
506 - document chaining of signal handler for SIGCHLD and child handlers
507 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
508 - generate a failure of a default event loop is executed out-of-thread
509 - maybe add support for inotify events
511 * investigate endianness issues of UUID vs. GUID
513 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
514 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
516 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
518 * add a pam module that on password changes updates any LUKS slot where the password matches
520 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
523 - add unit tests for config_parse_device_allow()
525 * seems that when we follow symlinks to units we prefer the symlink
526 destination path over /etc and /usr. We should not do that. Instead
527 /etc should always override /run+/usr and also any symlink
530 * when isolating, try to figure out a way how we implicitly can order
531 all units we stop before the isolating unit...
533 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
535 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
536 that the boot loader should be installed to the ESP. Define a way
537 how an installer can figure out whether a BLS compliant boot loader
540 * think about requeuing jobs when daemon-reload is issued? usecase:
541 the initrd issues a reload after fstab from the host is accessible
542 and we might want to requeue the mounts local-fs acquired through
545 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
547 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
549 * shutdown logging: store to EFI var, and store to USB stick?
551 * merge unit_kill_common() and unit_kill_context()
553 * introduce ExecCondition= in services
556 - honor language efi variables for default language selection (if there are any?)
557 - honor timezone efi variables for default timezone selection (if there are any?)
558 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
560 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
562 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
564 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
567 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
568 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
569 - logind: wakelock/opportunistic suspend support
570 - Add pretty name for seats in logind
571 - logind: allow showing logout dialog from system?
572 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
573 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
574 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
575 - if pam_systemd is invoked by su from a process that is outside of a
576 any session we should probably just become a NOP, since that's
577 usually not a real user session but just some system code that just
579 - logind: make the Suspend()/Hibernate() bus calls wait for the for
580 the job to be completed. before returning, so that clients can wait
581 for "systemctl suspend" to finish to know when the suspending is
583 - logind: when the power button is pressed short, just popup a
584 logout dialog. If it is pressed for 1s, do the usual
585 shutdown. Inspiration are Macs here.
586 - expose "Locked" property on logind sesison objects
587 - given that logind now lets PID 1 do all nasty work, we can
588 probably reduce the capability set it retains substantially.
589 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
590 - expose orientation sensors and tablet mode through logind
591 - maybe allow configuration of the StopTimeout for session scopes
592 - rename session scope so that it includes the UID. THat way
593 the session scope can be arranged freely in slices and we don't have
594 make assumptions about their slice anymore.
595 - follow PropertiesChanged state more closely, to deal with quick logouts and
598 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
601 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
602 - import and delete pstore filesystem content at startup
603 - journald: also get thread ID from client, plus thread name
604 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
605 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
606 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
607 - declare the local journal protocol stable in the wiki interface chart
608 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
609 - journald: when dropping msgs due to ratelimit make sure to write
610 "dropped %u messages" not only when we are about to print the next
611 message that works, but alraedy after a short tiemout
612 - check if we can make journalctl by default use --follow mode inside of less if called without args?
613 - maybe add API to send pairs of iovecs via sd_journal_send
614 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
615 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
616 and !FOOBAR for events without FOOBAR.
617 - journal: store timestamp of journal_file_set_offline() int he header,
618 so it is possible to display when the file was last synced.
619 - 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.
620 - journal: find a way to allow dropping history early, based on priority, other rules
621 - journal: When used on NFS, check payload hashes
622 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
623 - refuse taking lower-case variable names in sd_journal_send() and friends.
624 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
625 - journal: deal nicely with byte-by-byte copied files, especially regards header
626 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
627 - Replace utmp, wtmp, btmp, and lastlog completely with journal
628 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
629 - when a kernel driver logs in a tight loop, we should ratelimit that too.
630 - journald: optionally, log debug messages to /run but everything else to /var
631 - journald: when we drop syslog messages because the syslog socket is
632 full, make sure to write how many messages are lost as first thing
633 to syslog when it works again.
634 - change systemd-journal-flush into a service that stays around during
635 boot, and causes the journal to be moved back to /run on shutdown,
636 so that we do not keep /var busy. This needs to happen synchronously,
637 hence doing this via signals is not going to work.
638 - optionally support running journald from the command line for testing purposes in external projects
639 - journald: allow per-priority and per-service retention times when rotating/vacuuming
640 - journald: make use of uid-range.h to managed uid ranges to split
642 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
643 - improve journalctl performance by loading journal files
644 lazily. Encode just enough information in the file name, so that we
645 do not have to open it to know that it is not interesting for us, for
646 the most common operations.
647 - journal-or-kmsg is currently broken? See reverted
648 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
649 - man: document that corrupted journal files is nothing to act on
650 - rework journald sigbus stuff to use mutex
651 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
652 services that run under their own user ids, and use User= (but only
653 in a world where userns is ubiquitous since otherwise we cannot
654 invoke those daemons on the host AND in a container anymore). Also,
655 if LimitNPROC= is used without User= we should warn and refuse
657 - journalctl --verify: don't show files that are currently being
658 written to as FAIL, but instead show that their are being written to.
659 - add journalctl -H that talks via ssh to a remote peer and passes through
661 - add a version of --merge which also merges /var/log/journal/remote
662 - journalctl: -m should access container journals directly by enumerating
663 them via machined, and also watch containers coming and going.
664 Benefit: nspawn --ephemeral would start working nicely with the journal.
665 - assign MESSAGE_ID to log messages about failed services
667 * add a test if all entries in the catalog are properly formatted.
668 (Adding dashes in a catalog entry currently results in the catalog entry
669 being silently skipped. journalctl --update-catalog must warn about this,
670 and we should also have a unit test to check that all our message are OK.)
673 - document that deps in [Unit] sections ignore Alias= fields in
674 [Install] units of other units, unless those units are disabled
675 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
676 - document that service reload may be implemented as service reexec
677 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
678 - document systemd-journal-flush.service properly
679 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
680 - man: document the very specific env the shutdown drop-in tools live in
681 - man: add more examples to man pages
682 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
685 - add systemctl switch to dump transaction without executing it
686 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
687 - "systemctl disable" on a static unit prints no message and does
688 nothing. "systemctl enable" does nothing, and gives a bad message
689 about it. Should fix both to print nice actionable messages.
690 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
691 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
692 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
693 - systemctl: "Journal has been rotated since unit was started." message is misleading
694 - systemctl status output should include list of triggering units and their status
697 - "systemctl mask" should find all names by which a unit is accessible
698 (i.e. by scanning for symlinks to it) and link them all to /dev/null
701 - timer units should get the ability to trigger when:
702 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
704 - Modulate timer frequency based on battery state
706 * add libsystemd-password or so to query passwords during boot using the password agent logic
708 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
710 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
712 * make repeated alt-ctrl-del presses printing a dump
714 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
716 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
719 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
720 with seccomp. That should provide us with a useful log buffer that
721 systemd can log to during early boot, and disconnect container logs
722 from the kernel's logs.
723 - as soon as networkd has a bus interface, hook up --network-interface=,
724 --network-bridge= with networkd, to trigger netdev creation should an
726 - a nice way to boot up without machine id set, so that it is set at boot
727 automatically for supporting --ephemeral. Maybe hash the host machine id
728 together with the machine name to generate the machine id for the container
729 - fix logic always print a final newline on output.
730 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
731 - should optionally support receiving WATCHDOG=1 messages from its payload
733 - optionally automatically add FORWARD rules to iptables whenever nspawn is
734 running, remove them when shut down.
735 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
739 - refuse mounting over a mount point
740 - automatically discover .roothash files in dissect, similarly to nspawn
743 - add an API so that libvirt-lxc can inform us about network interfaces being
744 removed or added to an existing machine
745 - "machinectl migrate" or similar to copy a container from or to a
746 difference host, via ssh
747 - introduce systemd-nspawn-ephemeral@.service, and hook it into
748 "machinectl start" with a new --ephemeral switch
749 - "machinectl status" should also show internal logs of the container in
751 - "machinectl list-images" should show os-release data, as well as
752 machine-info data (including deployment level)
753 - "machinectl history"
755 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
756 shell in it, and marks it read-only after use
759 - generate a nice warning if mkfs.btrfs is missing
762 - cryptsetup-generator: allow specification of passwords in crypttab itself
763 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
765 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
766 https://bugs.freedesktop.org/show_bug.cgi?id=54712
768 * add a dependency on standard-conf.xml and other included files to man pages
770 * MountFlags=shared acts as MountFlags=slave right now.
772 * properly handle loop back mounts via fstab, especially regards to fsck/passno
774 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
779 - add trigger --subsystem-match=usb/usb_device device
780 - reimport udev db after MOVE events for devices without dev_t
782 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
784 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
787 - save coredump in Windows/Mozilla minidump format
788 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
790 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
792 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
794 * be able to specify a forced restart of service A where service B depends on, in case B
795 needs to be auto-respawned?
798 - apply "x" on "D" too (see patch from William Douglas)
800 - instead of ignoring unknown fields, reject them.
801 - creating new directories/subvolumes/fifos/device nodes
802 should not follow symlinks. None of the other adjustment or creation
803 calls follow symlinks.
805 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
807 * verify that the AF_UNIX sockets of a service in the fs still exist
808 when we start a service in order to avoid confusion when a user
809 assumes starting a service is enough to make it accessible
811 * Make it possible to set the keymap independently from the font on
812 the kernel cmdline. Right now setting one resets also the other.
814 * and a dbus call to generate target from current state
816 * write blog stories about:
817 - hwdb: what belongs into it, lsusb
818 - enabling dbus services
819 - how to make changes to sysctl and sysfs attributes
821 - how to pass throw-away units to systemd, or dynamically change properties of existing units
822 - testing with Harald's awesome test kit
824 - how to develop against journal browsing APIs
825 - the journal HTTP iface
826 - non-cgroup resource management
827 - dynamic resource management with cgroups
828 - refreshed, longer missions statement
829 - calendar time events
830 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
831 - how to create your own target
832 - instantiated apache, dovecot and so on
833 - hooking a script into various stages of shutdown/rearly booot
835 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
837 * dot output for --test showing the 'initial transaction'
840 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
841 log both units as UNIT=, so that journalctl -u triggers on both.
842 - generate better errors when people try to set transient properties
843 that are not supported...
844 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
845 - maybe introduce WantsMountsFor=? Usecase:
846 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
847 - recreate systemd's D-Bus private socket file on SIGUSR2
848 - move PAM code into its own binary
849 - when we automatically restart a service, ensure we restart its rdeps, too.
850 - hide PAM options in fragment parser when compile time disabled
851 - Support --test based on current system state
852 - 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().
853 - after deserializing sockets in socket.c we should reapply sockopts and things
854 - drop PID 1 reloading, only do reexecing (difficult: Reload()
855 currently is properly synchronous, Reexec() is weird, because we
856 cannot delay the response properly until we are back, so instead of
857 being properly synchronous we just keep open the fd and close it
858 when done. That means clients do not get a successful method reply,
859 but much rather a disconnect on success.
860 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
861 - when a bus name of a service disappears from the bus make sure to queue further activation requests
864 - allow port=0 in .socket units
865 - maybe introduce ExecRestartPre=
866 - add ReloadSignal= for configuring a reload signal to use
867 - implement Register= switch in .socket units to enable registration
868 in Avahi, RPC and other socket registration services.
869 - allow Type=simple with PIDFile=
870 https://bugzilla.redhat.com/show_bug.cgi?id=723942
871 - allow writing multiple conditions in unit files on one line
872 - load-fragment: when loading a unit file via a chain of symlinks
873 verify that it is not masked via any of the names traversed.
874 - introduce Type=pid-file
875 - introduce mix of BindTo and Requisite
876 - add a concept of RemainAfterExit= to scope units
877 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
880 - Make sure ID_PATH is always exported and complete for
881 network devices where possible, so we can safely rely
883 - check MTUBytes parsing (expecting size_t but we are using unsigned)
886 - add support for more attribute types
887 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
890 - add more keys to [Route] and [Address] sections
891 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
892 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
893 - add reduced [Link] support to .network files
894 - add Scope= parsing option for [Network]
895 - properly handle routerless dhcp leases
896 - work with non-Ethernet devices
897 - add support for more bond options
898 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
899 - the DHCP lease data (such as NTP/DNS) is still made available when
900 a carrier is lost on a link. It should be removed instantly.
901 - expose in the API the following bits:
902 - option 15, domain name and/or option 119, search list
903 - option 12, host name and/or option 81, fqdn
904 - option 123, 144, geolocation
905 - option 252, configure http proxy (PAC/wpad)
906 - provide a way to define a per-network interface default metric value
907 for all routes to it. possibly a second default for DHCP routes.
908 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
909 support Name=foo*|bar*|baz ?
910 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
911 - allow DUID/IAID to be customized, see issue #394.
912 - whenever uplink info changes, make DHCP server send out FORCERENEW
914 * networkd-wait-online:
915 - make operstates to wait for configurable?
918 - figure out how much we can increase Maximum Message Size
921 - add functions to set previously stored IPv6 addresses on startup and get
922 them at shutdown; store them in client->ia_na
923 - write more test cases
924 - implement reconfigure support, see 5.3., 15.11. and 22.20.
925 - implement support for temporary adressess (IA_TA)
926 - implement dhcpv6 authentication
927 - investigate the usefulness of Confirm messages; i.e. are there any
928 situations where the link changes without any loss in carrier detection
930 - some servers don't do rapid commit without a filled in IA_NA, verify
937 - natively watch for dbus-*.service symlinks (PENDING)
938 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
940 * fix alsa mixer restore to not print error when no config is stored
942 * make cryptsetup lower --iter-time
944 * patch kernel for xattr support in /dev, /proc/, /sys?
946 * kernel: add device_type = "fb", "fbcon" to class "graphics"
948 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
950 * /usr/bin/service should actually show the new command line
952 * 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=
954 * fedora: F20: go timer units all the way, leave cron.daily for cron
956 * neither pkexec nor sudo initialize environ[] from the PAM environment?
958 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
960 * register catalog database signature as file magic
962 * zsh shell completion:
963 - <command> <verb> -<TAB> should complete options, but currently does not
964 - systemctl add-wants,add-requires
969 * look for close() vs. close_nointr() vs. close_nointr_nofail()
971 * check for strerror(r) instead of strerror(-r)
975 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
977 * use secure_getenv() instead of getenv() where appropriate
979 * link up selected blog stories from man pages and unit files Documentation= fields
