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
15 * When systemctl --host is used, underlying ssh connection can remain open.
16 bus_close does not kill children?
20 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
22 * wiki: update journal format documentation for lz4 additions
24 * When lz4 gets an API for lz4 command output, make use of it to
25 compress coredumps in a way compatible with /usr/bin/lz4.
29 * sd-event: maybe add support for inotify events
31 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
33 * nspawn should send out sd_notify("WATCHDOG=1") messages
35 * nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
37 * consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
39 * "systemctl edit" should know a mode to create a new unit file
41 * there's probably something wrong with having user mounts below /sys,
42 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
43 prefixed with /sys generally special.
44 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
46 * Add PassEnvironment= setting to service units, to import select env vars from PID 1 into the service env block
48 * nspawn: fix logic always print a final newline on output.
49 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
51 * make nspawn's --network-veth switch more powerful:
52 http://lists.freedesktop.org/archives/systemd-devel/2015-June/033121.html
54 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
56 * man: clarify that "machinectl show" shows different information than "machinectl status" (no cgroup tree, no IP addresses, ...)
58 * "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
60 * install: include generator dirs in unit file search paths
62 * stop using off_t, it's a crazy type. Use uint64_t instead.
64 * logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
66 * invent a better systemd-run scheme for naming scopes, that works with remoting
68 * add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
70 * change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
72 * add a version of --merge which also merges /var/log/journal/remote
74 * log accumulated resource usage after each service invocation
76 * nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container
78 * logind: rename session scope so that it includes the UID. THat way
79 the session scope can be arranged freely in slices and we don't have
80 make assumptions about their slice anymore.
82 * journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal.
84 * nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
86 * nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
88 * importd: generate a nice warning if mkfs.btrfs is missing
90 * nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers
92 * nspawn: Improve error message when --bind= is used on a non-existing source directory
94 * nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
96 * man: document how update dkr images works with machinectl
97 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
99 * nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing
101 * rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
102 to unicode chars, to make things more expressive.
104 * "machinectl migrate" or similar to copy a container from or to a
105 difference host, via ssh
107 * tmpfiles: creating new directories/subvolumes/fifos/device nodes
108 should not follow symlinks. None of the other adjustment or creation
109 calls follow symlinks.
111 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
113 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
115 * mounting and unmounting mount points manually with different source
116 devices will result in collected collected on all devices used.
117 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
119 * add a job mode that will fail if a transaction would mean stopping
120 running units. Use this in timedated to manage the NTP service
122 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
124 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
125 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
127 * .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
129 * create a btrfs qgroup for /var/lib/machines, and add all container
130 subvolumes we create to it.
132 * When logging about multiple units (stopping BoundTo units, conflicts, etc.),
133 log both units as UNIT=, so that journalctl -u triggers on both.
135 * to allow "linking" of nspawn containers, extend --network-bridge= so
136 that it can dynamically create bridge interfaces that are refcounted
137 by the containers on them. For each group of containers to link together
139 * journalctl --verify: don't show files that are currently being
140 written to as FAIL, but instead show that their are being written
143 * assign MESSAGE_ID to log messages about failed services
145 * coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
146 and supress coredump if turned off. Then change RLIMIT_CORE to
147 infinity by default for all services. This then allows per-service
148 control of coredumping.
150 * generate better errors when people try to set transient properties
151 that are not supported...
152 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
154 * Introduce $LISTEN_NAMES to complement $LISTEN_FDS, containing a
155 colon separated list of identifiers for the fds passed.
157 * maybe introduce WantsMountsFor=? Usecase:
158 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
160 * rework kexec logic to use new kexec_file_load() syscall, so that we
161 don't have to call kexec tool anymore.
163 * The udev blkid built-in should expose a property that reflects
164 whether media was sensed in USB CF/SD card readers. This should then
165 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
166 picked up by systemd unless they contain a medium. This would mirror
167 the behaviour we already have for CD drives.
169 * nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
170 with seccomp. That should provide us with a useful log buffer that
171 systemd can log to during early boot, and disconnect container logs
172 from the kernel's logs.
174 * networkd/udev: implement SR_IOV configuration in .link files:
175 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
177 * When RLIMIT_NPROC is set from a unit file it currently always is set
178 for root, not for the user set in User=, which makes it
179 useless. After fixing this, set RLIMIT_NPROC for
180 systemd-journal-xyz, and all other of our services that run under
181 their own user ids, and use User= (but only in a world where userns
182 is ubiquitous since otherwise we cannot invoke those daemons on the
183 host AND in a container anymore). Also, if LimitNPROC= is used
184 without User= we should warn and refuse operation.
186 * logind: maybe allow configuration of the StopTimeout for session scopes
188 * Set NoNewPrivileges= on all of our own services, where that makes sense
190 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
192 * rework journald sigbus stuff to use mutex
194 * import-dkr: support tarsum checksum verification, if it becomes reality one day...
196 * import-dkr: convert json bits to nspawn configuration
198 * core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall
200 * introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
202 * "machinectl status" should also show internal logs of the container in question
204 * "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
206 * Port various tools to make use of verbs.[ch], where applicable
208 * "machinectl history"
212 * "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
214 * systemd-nspawn -x should support ephemeral instances of gpt images
216 * hostnamectl: show root image uuid
218 * sysfs set api in libudev is not const
220 * Find a solution for SMACK capabilities stuff:
221 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
223 * port libmount hookup to use API's own inotify interface, as soon as that is table in libmount
225 * "systemctl preset-all" should probably order the unit files it
226 operates on lexicographically before starting to work, in order to
227 ensure deterministic behaviour if two unit files conflict (like DMs
230 * resolved should optionally register additional per-interface LLMNR
231 names, so that for the container case we can establish the same name
232 (maybe "host") for referencing the server, everywhere.
234 * systemd-journal-upload (or a new, related tool): allow pushing out
235 journal messages onto the network in BSD syslog protocol,
236 continuously. Default to some link-local IP mcast group, to make this
237 useful as a one-stop debugging tool.
239 * synchronize console access with BSD locks:
240 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
242 * as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
243 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
245 * the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
247 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
249 * figure out when we can use the coarse timers
251 * add "systemctl start -v foobar.service" that shows logs of a service
252 while the start command runs. This is non-trivial to do without
253 races though, since we should flush out all journal messages before
254 returning from the "systemctl stop".
256 * 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
258 * timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
260 * add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
262 * machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
264 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
266 * code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
268 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
270 * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
272 * consider showing the unit names during boot up in the status output, not just the unit descriptions
274 * dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
276 * maybe allow timer units with an empty Units= setting, so that they
277 can be used for resuming the system but nothing else.
279 * what to do about udev db binary stability for apps? (raw access is not an option)
281 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
283 * maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
285 * man: document that corrupted journal files is nothing to act on
287 * man: maybe use the word "inspect" rather than "introspect"?
289 * "machinectl list" should probably show columns for OS version and IP addresses
291 * systemctl: if some operation fails, show log output?
294 - allow creation of units from scratch
295 - use equvalent of cat() to insert existing config as a comment, prepended with #.
296 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
298 * refcounting in sd-resolve is borked
300 * exponential backoff in timesyncd and resolved when we cannot reach a server
302 * extract_many_words() should probably be used by a lot of code that
303 currently uses FOREACH_WORD and friends. For example, most conf
304 parsing callbacks should use it.
306 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
308 * systemd.show_status= should probably have a mode where only failed
311 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
312 (throughout the codebase, not only PID1)
315 - add LLDP client side support
316 - the DHCP lease data (such as NTP/DNS) is still made available when
317 a carrier is lost on a link. It should be removed instantly.
318 - expose in the API the following bits:
319 - option 15, domain name and/or option 119, search list
320 - option 12, host name and/or option 81, fqdn
321 - option 123, 144, geolocation
322 - option 252, configure http proxy (PAC/wpad)
323 - provide a way to define a per-network interface default metric value
324 for all routes to it. possibly a second default for DHCP routes.
325 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
326 support Name=foo*|bar*|baz ?
327 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
328 - allow DUID/IAID to be customized, see issue #394.
329 - support configuration option for TSO (tcp segmentation offload)
330 - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW
333 - put networkd events and rtnl events at a higher priority, so that
334 we always process them before we process client requests
336 - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
341 - DNS-SD service registration from socket units
343 - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
344 announce dname support. However, for DNSSEC it is necessary as the synthesized cname
348 * Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
350 * Add a new verb "systemctl top"
352 * add new gpt type for btrfs volumes
354 * support empty /etc boots nicely:
355 - nspawn/gpt-generator: introduce new gpt partition type for /usr
356 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
358 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
360 * timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
362 * a way for container managers to turn off getty starting via $container_headless= or so...
364 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
366 * mount_cgroup_controllers(): symlinks need to get the label applied
368 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
369 they run added to the initial transaction and thus confuse Type=idle.
371 * Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
373 * sd-event: generate a failure of a default event loop is executed out-of-thread
375 * add bus api to query unit file's X fields.
377 * consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
379 * sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
381 * gpt-auto-generator:
382 - Support LUKS for root devices
383 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
384 - Make /home automount rather than mount?
386 * add generator that pulls in systemd-network from containers when
387 CAP_NET_ADMIN is set, more than the loopback device is defined, even
388 when it is otherwise off
390 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
392 * "busctl status" works only as root on dbus1, since we cannot read
395 * implement Distribute= in socket units to allow running multiple
396 service instances processing the listening socket, and open this up
399 * socket units: support creating sockets in different namespace,
400 opening it up for JoinsNamespaceOf=. This would require to fork off
401 a tiny process that joins the namespace and creates/binds the socket
402 and passes this back to PID1 via SCM_RIGHTS. This also could be used
403 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
405 * New service property: maximum CPU and wallclock runtime for a service
407 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
408 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
409 should SIGSTOP all unit processes in a loop until all processes of
410 it are fully stopped. This can later be used for app management by
411 desktop UIs such as gnome-shell to freeze apps that are not visible
412 on screen, not unlike how job control works on the shell
415 - implement per-slice CPUFairScheduling=1 switch
416 - handle jointly mounted controllers correctly
417 - introduce high-level settings for RT budget, swappiness
418 - how to reset dynamically changed unit cgroup attributes sanely?
419 - when reloading configuration, apply new cgroup configuration
420 - when recursively showing the cgroup hierarchy, optionally also show
421 the hierarchies of child processes
424 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
425 - ensure scope units may be started only a single time
427 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
429 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
431 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
433 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
435 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
437 * unify dispatch table in systemctl_main() and friends
439 * 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
441 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
443 * If we try to find a unit via a dangling symlink, generate a clean
444 error. Currently, we just ignore it and read the unit from the search
447 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
449 * btrfs raid assembly: some .device jobs stay stuck in the queue
451 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
453 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
455 * load .d/*.conf dropins for device units
457 * allow implementation of InaccessibleDirectories=/ plus
458 ReadOnlyDirectories=... for whitelisting files for a service.
462 - GetAllProperties() on a non-existing object does not result in a failure currently
463 - kdbus: process fd=-1 for incoming msgs
464 - port to sd-resolve for connecting to TCP dbus servers
465 - kdbus: maybe add controlling tty metadata fields
466 - 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
467 - when kdbus does not take our message without memfds, try again with memfds
468 - see if we can drop more message validation on the sending side
469 - add API to clone sd_bus_message objects
470 - make AddMatch calls on dbus1 transports async?
471 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
472 - longer term: priority inheritance
475 - NameLost/NameAcquired obsolete
478 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
479 - test bloom filter generation indexes
480 - bus-proxy: when passing messages from kdbus, make sure we properly
481 handle the case where a large number of fds is appended that we
482 cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
484 - kdbus: introduce a concept of "send-only" connections
485 - kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
488 - allow multiple signal handlers per signal?
489 - document chaining of signal handler for SIGCHLD and child handlers
491 * in the final killing spree, detect processes from the root directory, and
492 complain loudly if they have argv[0][0] == '@' set.
493 https://bugzilla.redhat.com/show_bug.cgi?id=961044
495 * investigate endianness issues of UUID vs. GUID
497 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
498 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
500 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
502 * add a pam module that on password changes updates any LUKS slot where the password matches
504 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
506 * cgtop: make cgtop useful in a container
509 - add 'set -e' to scripts in test/
510 - make stuff in test/ work with separate output dir
512 * seems that when we follow symlinks to units we prefer the symlink
513 destination path over /etc and /usr. We should not do that. Instead
514 /etc should always override /run+/usr and also any symlink
517 * when isolating, try to figure out a way how we implicitly can order
518 all units we stop before the isolating unit...
520 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
522 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
523 that the boot loader should be installed to the ESP. Define a way
524 how an installer can figure out whether a BLS compliant boot loader
527 * think about requeuing jobs when daemon-reload is issued? usecase:
528 the initrd issues a reload after fstab from the host is accessible
529 and we might want to requeue the mounts local-fs acquired through
532 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
534 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
536 * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
538 * shutdown logging: store to EFI var, and store to USB stick?
540 * write UI tool that pops up emergency messages from the journal as notification
542 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
544 * merge unit_kill_common() and unit_kill_context()
546 * introduce ExecCondition= in services
549 - honor language efi variables for default language selection (if there are any?)
550 - honor timezone efi variables for default timezone selection (if there are any?)
551 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
553 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
555 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
556 https://bugzilla.redhat.com/show_bug.cgi?id=812826
558 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
560 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
563 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
564 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
565 - logind: wakelock/opportunistic suspend support
566 - Add pretty name for seats in logind
567 - logind: allow showing logout dialog from system?
568 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
569 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
570 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
571 - if pam_systemd is invoked by su from a process that is outside of a
572 any session we should probably just become a NOP, since that's
573 usually not a real user session but just some system code that just
575 - logind: make the Suspend()/Hibernate() bus calls wait for the for
576 the job to be completed. before returning, so that clients can wait
577 for "systemctl suspend" to finish to know when the suspending is
579 - logind: when the power button is pressed short, just popup a
580 logout dialog. If it is pressed for 1s, do the usual
581 shutdown. Inspiration are Macs here.
582 - expose "Locked" property on logind sesison objects
583 - given that logind now lets PID 1 do all nasty work, we can
584 probably reduce the capability set it retains substantially.
585 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
586 - expose orientation sensors and tablet mode through logind
588 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
590 * service: watchdog logic: for testing purposes allow ping, but do not require pong
593 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
594 - import and delete pstore filesystem content at startup
595 - journald: also get thread ID from client, plus thread name
596 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
597 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
598 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
599 - declare the local journal protocol stable in the wiki interface chart
600 - journal: reuse XZ context
601 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
602 - journald: when dropping msgs due to ratelimit make sure to write
603 "dropped %u messages" not only when we are about to print the next
604 message that works, but alraedy after a short tiemout
605 - check if we can make journalctl by default use --follow mode inside of less if called without args?
606 - maybe add API to send pairs of iovecs via sd_journal_send
607 - journal: when writing journal auto-rotate if time jumps backwards
608 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
609 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
610 and !FOOBAR for events without FOOBAR.
611 - journal: store timestamp of journal_file_set_offline() int he header,
612 so it is possible to display when the file was last synced.
613 - 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.
614 - journal: find a way to allow dropping history early, based on priority, other rules
615 - journal: When used on NFS, check payload hashes
616 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
617 - refuse taking lower-case variable names in sd_journal_send() and friends.
618 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
619 - journal: deal nicely with byte-by-byte copied files, especially regards header
620 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
621 - Replace utmp, wtmp, btmp, and lastlog completely with journal
622 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
623 - when a kernel driver logs in a tight loop, we should ratelimit that too.
624 - journald: optionally, log debug messages to /run but everything else to /var
625 - journald: when we drop syslog messages because the syslog socket is
626 full, make sure to write how many messages are lost as first thing
627 to syslog when it works again.
628 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
629 - change systemd-journal-flush into a service that stays around during
630 boot, and causes the journal to be moved back to /run on shutdown,
631 so that we do not keep /var busy. This needs to happen synchronously,
632 hence doing this via signals is not going to work.
633 - optionally support running journald from the command line for testing purposes in external projects
634 - journald: allow per-priority and per-service retention times when rotating/vacuuming
635 - journald: make use of uid-range.h to managed uid ranges to split
637 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
638 - improve journalctl performance by loading journal files
639 lazily. Encode just enough information in the file name, so that we
640 do not have to open it to know that it is not interesting for us, for
641 the most common operations.
644 - document that deps in [Unit] sections ignore Alias= fields in
645 [Install] units of other units, unless those units are disabled
646 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
647 - document the exit codes when services fail before they are exec()ed
648 - document that service reload may be implemented as service reexec
649 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
650 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
651 - document systemd-journal-flush.service properly
652 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
653 - man: document the very specific env the shutdown drop-in tools live in
654 - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
655 - man: add more examples to man pages
656 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
659 - systemctl list-jobs - show dependencies
660 - add systemctl switch to dump transaction without executing it
661 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
662 - "systemctl disable" on a static unit prints no message and does
663 nothing. "systemctl enable" does nothing, and gives a bad message
664 about it. Should fix both to print nice actionable messages.
665 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
666 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
667 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
668 - systemctl: "Journal has been rotated since unit was started." message is misleading
669 - support "systemctl stop foobar@.service" to stop all units matching a certain template
670 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
671 - better error message if you run systemctl without systemd running
672 - systemctl status output should should include list of triggering units and their status
675 - "systemctl mask" should find all names by which a unit is accessible
676 (i.e. by scanning for symlinks to it) and link them all to /dev/null
677 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
680 - timer units should get the ability to trigger when:
681 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
683 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
684 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
685 - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
686 - Modulate timer frequency based on battery state
688 * add libsystemd-password or so to query passwords during boot using the password agent logic
690 * 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().
692 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
694 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
696 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
697 waiting for the timeout
699 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
701 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
704 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
707 - cryptsetup-generator: allow specification of passwords in crypttab itself
708 - move cryptsetup key caching into kernel keyctl?
709 https://bugs.freedesktop.org/show_bug.cgi?id=54982
710 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
712 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
713 https://bugs.freedesktop.org/show_bug.cgi?id=54712
715 * after deserializing sockets in socket.c we should reapply sockopts and things
717 * make timer units go away after they elapsed
719 * move PID 1 segfaults to /var/lib/systemd/coredump?
721 * create /sbin/init symlinks from the build system
723 * allow writing multiple conditions in unit files on one line
725 * MountFlags=shared acts as MountFlags=slave right now.
727 * drop PID 1 reloading, only do reexecing (difficult: Reload()
728 currently is properly synchronous, Reexec() is weird, because we
729 cannot delay the response properly until we are back, so instead of
730 being properly synchronous we just keep open the fd and close it
731 when done. That means clients do not get a successful method reply,
732 but much rather a disconnect on success.
734 * properly handle loop back mounts via fstab, especially regards to fsck/passno
736 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
738 * rename "userspace" to "core-os"
740 * load-fragment: when loading a unit file via a chain of symlinks
741 verify that it is not masked via any of the names traversed.
743 * introduce Type=pid-file
745 * change Requires=basic.target to RequisiteOverride=basic.target
747 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
749 * ExecOnFailure=/usr/bin/foo
754 - add trigger --subsystem-match=usb/usb_device device
755 - reimport udev db after MOVE events for devices without dev_t
757 * when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
759 * introduce mix of BindTo and Requisite
761 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
763 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
765 * default unix qlen is too small (10). bump sysctl? add sockopt?
767 * save coredump in Windows/Mozilla minidump format
769 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
771 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
773 * be able to specify a forced restart of service A where service B depends on, in case B
774 needs to be auto-respawned?
776 * when a bus name of a service disappears from the bus make sure to queue further activation requests
779 - apply "x" on "D" too (see patch from William Douglas)
781 - instead of ignoring unknown fields, reject them.
783 * for services: do not set $HOME in services unless requested
785 * hide PAM options in fragment parser when compile time disabled
787 * when we automatically restart a service, ensure we restart its rdeps, too.
789 * allow Type=simple with PIDFile=
790 https://bugzilla.redhat.com/show_bug.cgi?id=723942
792 * move PAM code into its own binary
794 * implement Register= switch in .socket units to enable registration
795 in Avahi, RPC and other socket registration services.
797 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
799 * add ReloadSignal= for configuring a reload signal to use
801 * verify that the AF_UNIX sockets of a service in the fs still exist
802 when we start a service in order to avoid confusion when a user
803 assumes starting a service is enough to make it accessible
805 * Make it possible to set the keymap independently from the font on
806 the kernel cmdline. Right now setting one resets also the other.
808 * and a dbus call to generate target from current state
810 * GC unreferenced jobs (such as .device jobs)
812 * write blog stories about:
813 - hwdb: what belongs into it, lsusb

829 - instantiated apache, dovecot and so on
830 - hooking a script into various stages of shutdown/rearly booot
832 * allow port=0 in .socket units
834 * recreate systemd's D-Bus private socket file on SIGUSR2
836 * Support --test based on current system state
838 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
840 * maybe introduce ExecRestartPre=
842 * dot output for --test showing the 'initial transaction'
844 * fingerprint.target, wireless.target, gps.target, netdevice.target
847 - figure out a simple way to wait for journal events in a way that
849 - add documentation to systemd.daemon
852 - plot per-process IO utilization
853 - group processes based on service association (cgroups)
854 - document initcall_debug
855 - kernel cmdline "bootchart" option for simplicity?
858 - Make sure ID_PATH is always exported and complete for
859 network devices where possible, so we can safely rely
861 - check MTUBytes parsing (expecting size_t but we are using unsigned)
864 - add support for more attribute types
865 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
868 - add more keys to [Route] and [Address] sections
869 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
870 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
871 - add reduced [Link] support to .network files
872 - add Scope= parsing option for [Network]
873 - properly handle routerless dhcp leases
874 - add more attribute support for SIT tunnel

879 - make operstates to wait for configurable?
882 - figure out how much we can increase Maximum Message Size
883 - support RFC4702 (pass FQDN)
886 - add functions to set previously stored IPv6 addresses on startup and get
887 them at shutdown; store them in client->ia_na
888 - write more test cases
889 - implement reconfigure support, see 5.3., 15.11. and 22.20.
890 - implement support for temporary adressess (IA_TA)
891 - implement dhcpv6 authentication
892 - investigate the usefulness of Confirm messages; i.e. are there any
893 situations where the link changes without any loss in carrier detection
895 - some servers don't do rapid commit without a filled in IA_NA, verify
901 - natively watch for dbus-*.service symlinks (PENDING)
902 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
904 * fix alsa mixer restore to not print error when no config is stored
906 * make cryptsetup lower --iter-time
908 * patch kernel for xattr support in /dev, /proc/, /sys?
910 * kernel: add device_type = "fb", "fbcon" to class "graphics"
912 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
914 * dbus upstream still refers to dbus.target and should not
916 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
918 * add "# export SYSTEMD_PAGER=" to bash login
920 * /usr/bin/service should actually show the new command line
922 * 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=
924 * fedora: F20: go timer units all the way, leave cron.daily for cron
926 * neither pkexec nor sudo initialize environ[] from the PAM environment?
928 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
930 * register catalog database signature as file magic
932 * zsh shell completion:
933 - <command> <verb> -<TAB> should complete options, but currently does not
934 - systemctl add-wants,add-requires
939 * look for close() vs. close_nointr() vs. close_nointr_nofail()
941 * check for strerror(r) instead of strerror(-r)
943 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
947 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
949 * use secure_getenv() instead of getenv() where appropriate
951 * link up selected blog stories from man pages and unit files Documentation= fields
953 Scheduled for removal or fixing:
955 * xxxOverridable dependencies (probably: fix)
