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
26 * code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
28 * replace manual readdir() loops with FOREACH_DIRENT or FOREACH_DIRENT_ALL
30 * Get rid of the last strerror() invocations in favour of %m and strerror_r()
32 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
36 * cache sd_event_now() result from before the first iteration...
38 * remove Capabilities=, after all AmbientCapabilities= and CapabilityBoundingSet= should be enough.
40 * support for the new copy_file_range() syscall
42 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
44 * coredump logic should use prlimit() to query RLIMIT_CORE of the dumpee and honour it
46 * Add a MaxRuntimeSec= setting for service units (or units in general) to terminate units after they ran for a certain
49 * Maybe add a way how users can "pin" units into memory, so that they are not subject to automatic GC?
51 * PID1: find a way how we can reload unit file configuration for
52 specific units only, without reloading the whole of systemd
54 * add an explicit parser for LimitNICE= and LimitRTPRIO= that verifies
55 the specified range and generates sane error messages for incorrect
56 specifications. Also, for LimitNICE= maybe introduce a syntax such
57 as "+5" or "-7" in order to make the limits more readable as they
58 are otherwise shifted by 20.
60 * do something about "/control" subcgroups in the unified cgroup hierarchy
62 * when we detect that there are waiting jobs but no running jobs, do something
64 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
66 * add a new command "systemctl revert" or so, that removes all dropin
67 snippets in /run and /etc, and all unit files with counterparts in
68 /usr, and thus undoes what "systemctl set-property" and "systemctl
69 edit" create. Maybe even add "systemctl revert -a" to do this for
72 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
74 * consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
76 * "systemctl edit" should know a mode to create a new unit file
78 * there's probably something wrong with having user mounts below /sys,
79 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
80 prefixed with /sys generally special.
81 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
83 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
85 * "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
87 * install: include generator dirs in unit file search paths
89 * rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
90 to unicode chars, to make things more expressive.
92 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
94 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
96 * mounting and unmounting mount points manually with different source
97 devices will result in collected collected on all devices used.
98 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
100 * add a job mode that will fail if a transaction would mean stopping
101 running units. Use this in timedated to manage the NTP service
103 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
105 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
106 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
108 * The udev blkid built-in should expose a property that reflects
109 whether media was sensed in USB CF/SD card readers. This should then
110 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
111 picked up by systemd unless they contain a medium. This would mirror
112 the behaviour we already have for CD drives.
114 * networkd/udev: implement SR_IOV configuration in .link files:
115 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
117 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
119 * implement a per-service firewall based on net_cls
121 * Port various tools to make use of verbs.[ch], where applicable
123 * hostnamectl: show root image uuid
125 * sysfs set api in libudev is not const
127 * Find a solution for SMACK capabilities stuff:
128 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
130 * "systemctl preset-all" should probably order the unit files it
131 operates on lexicographically before starting to work, in order to
132 ensure deterministic behaviour if two unit files conflict (like DMs
135 * synchronize console access with BSD locks:
136 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
138 * as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
139 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
141 * the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
143 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
145 * figure out when we can use the coarse timers
147 * add "systemctl start -v foobar.service" that shows logs of a service
148 while the start command runs. This is non-trivial to do without
149 races though, since we should flush out all journal messages before
150 returning from the "systemctl stop".
152 * 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
154 * 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
156 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
158 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
160 * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
162 * consider showing the unit names during boot up in the status output, not just the unit descriptions
164 * maybe allow timer units with an empty Units= setting, so that they
165 can be used for resuming the system but nothing else.
167 * what to do about udev db binary stability for apps? (raw access is not an option)
169 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
171 * man: maybe use the word "inspect" rather than "introspect"?
173 * systemctl: if some operation fails, show log output?
176 - allow creation of units from scratch
177 - use equvalent of cat() to insert existing config as a comment, prepended with #.
178 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
180 * exponential backoff in timesyncd and resolved when we cannot reach a server
182 * timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
184 * extract_many_words() should probably be used by a lot of code that
185 currently uses FOREACH_WORD and friends. For example, most conf
186 parsing callbacks should use it.
188 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
190 * systemd.show_status= should probably have a mode where only failed
193 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
194 (throughout the codebase, not only PID1)
197 - put networkd events and rtnl events at a higher priority, so that
198 we always process them before we process client requests
200 - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
201 - synthesize negative cache entries from NSEC/NSEC3 and drop explicit negative caching of authenticated answers
204 - service registration
205 - service/domain/types browsing
207 - DNS-SD service registration from socket units
208 - resolved should optionally register additional per-interface LLMNR
209 names, so that for the container case we can establish the same name
210 (maybe "host") for referencing the server, everywhere.
211 - add API so NM can push DNS server info into resolved
213 * refcounting in sd-resolve is borked
215 * Add a new verb "systemctl top"
217 * add new gpt type for btrfs volumes
219 * support empty /etc boots nicely:
220 - nspawn/gpt-generator: introduce new gpt partition type for /usr
221 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
223 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
225 * a way for container managers to turn off getty starting via $container_headless= or so...
227 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
229 * mount_cgroup_controllers(): symlinks need to get the label applied
231 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
232 they run added to the initial transaction and thus confuse Type=idle.
234 * 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)
236 * add bus api to query unit file's X fields.
238 * gpt-auto-generator:
239 - Support LUKS for root devices
240 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
241 - Make /home automount rather than mount?
243 * add generator that pulls in systemd-network from containers when
244 CAP_NET_ADMIN is set, more than the loopback device is defined, even
245 when it is otherwise off
247 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
249 * "busctl status" works only as root on dbus1, since we cannot read
252 * implement Distribute= in socket units to allow running multiple
253 service instances processing the listening socket, and open this up
256 * socket units: support creating sockets in different namespace,
257 opening it up for JoinsNamespaceOf=. This would require to fork off
258 a tiny process that joins the namespace and creates/binds the socket
259 and passes this back to PID1 via SCM_RIGHTS. This also could be used
260 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
262 * New service property: maximum CPU and wallclock runtime for a service
264 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
265 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
266 should SIGSTOP all unit processes in a loop until all processes of
267 it are fully stopped. This can later be used for app management by
268 desktop UIs such as gnome-shell to freeze apps that are not visible
269 on screen, not unlike how job control works on the shell
272 - implement per-slice CPUFairScheduling=1 switch
273 - handle jointly mounted controllers correctly
274 - introduce high-level settings for RT budget, swappiness
275 - how to reset dynamically changed unit cgroup attributes sanely?
276 - when reloading configuration, apply new cgroup configuration
277 - when recursively showing the cgroup hierarchy, optionally also show
278 the hierarchies of child processes
281 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
282 - ensure scope units may be started only a single time
284 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
286 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
288 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
290 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
292 * unify dispatch table in systemctl_main() and friends
294 * 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
296 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
298 * If we try to find a unit via a dangling symlink, generate a clean
299 error. Currently, we just ignore it and read the unit from the search
302 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
304 * btrfs raid assembly: some .device jobs stay stuck in the queue
306 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
308 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
310 * load .d/*.conf dropins for device units
312 * allow implementation of InaccessibleDirectories=/ plus
313 ReadOnlyDirectories=... for whitelisting files for a service.
317 - GetAllProperties() on a non-existing object does not result in a failure currently
318 - kdbus: process fd=-1 for incoming msgs
319 - port to sd-resolve for connecting to TCP dbus servers
320 - kdbus: maybe add controlling tty metadata fields
321 - 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
322 - when kdbus does not take our message without memfds, try again with memfds
323 - see if we can drop more message validation on the sending side
324 - add API to clone sd_bus_message objects
325 - make AddMatch calls on dbus1 transports async?
326 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
327 - longer term: priority inheritance
330 - NameLost/NameAcquired obsolete
333 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
334 - test bloom filter generation indexes
335 - bus-proxy: when passing messages from kdbus, make sure we properly
336 handle the case where a large number of fds is appended that we
337 cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
339 - kdbus: introduce a concept of "send-only" connections
340 - 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.
343 - allow multiple signal handlers per signal?
344 - document chaining of signal handler for SIGCHLD and child handlers
345 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
346 - generate a failure of a default event loop is executed out-of-thread
347 - maybe add support for inotify events
349 * in the final killing spree, detect processes from the root directory, and
350 complain loudly if they have argv[0][0] == '@' set.
351 https://bugzilla.redhat.com/show_bug.cgi?id=961044
353 * investigate endianness issues of UUID vs. GUID
355 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
356 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
358 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
360 * add a pam module that on password changes updates any LUKS slot where the password matches
362 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
364 * cgtop: make cgtop useful in a container
367 - add 'set -e' to scripts in test/
368 - make stuff in test/ work with separate output dir
370 * seems that when we follow symlinks to units we prefer the symlink
371 destination path over /etc and /usr. We should not do that. Instead
372 /etc should always override /run+/usr and also any symlink
375 * when isolating, try to figure out a way how we implicitly can order
376 all units we stop before the isolating unit...
378 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
380 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
381 that the boot loader should be installed to the ESP. Define a way
382 how an installer can figure out whether a BLS compliant boot loader
385 * think about requeuing jobs when daemon-reload is issued? usecase:
386 the initrd issues a reload after fstab from the host is accessible
387 and we might want to requeue the mounts local-fs acquired through
390 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
392 * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
394 * shutdown logging: store to EFI var, and store to USB stick?
396 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
398 * merge unit_kill_common() and unit_kill_context()
400 * introduce ExecCondition= in services
403 - honor language efi variables for default language selection (if there are any?)
404 - honor timezone efi variables for default timezone selection (if there are any?)
405 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
407 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
409 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
411 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
414 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
415 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
416 - logind: wakelock/opportunistic suspend support
417 - Add pretty name for seats in logind
418 - logind: allow showing logout dialog from system?
419 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
420 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
421 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
422 - if pam_systemd is invoked by su from a process that is outside of a
423 any session we should probably just become a NOP, since that's
424 usually not a real user session but just some system code that just
426 - logind: make the Suspend()/Hibernate() bus calls wait for the for
427 the job to be completed. before returning, so that clients can wait
428 for "systemctl suspend" to finish to know when the suspending is
430 - logind: when the power button is pressed short, just popup a
431 logout dialog. If it is pressed for 1s, do the usual
432 shutdown. Inspiration are Macs here.
433 - expose "Locked" property on logind sesison objects
434 - given that logind now lets PID 1 do all nasty work, we can
435 probably reduce the capability set it retains substantially.
436 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
437 - expose orientation sensors and tablet mode through logind
438 - maybe allow configuration of the StopTimeout for session scopes
439 - rename session scope so that it includes the UID. THat way
440 the session scope can be arranged freely in slices and we don't have
441 make assumptions about their slice anymore.
442 - follow PropertiesChanged state more closely, to deal with quick logouts and
445 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
447 * service: watchdog logic: for testing purposes allow ping, but do not require pong
450 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
451 - import and delete pstore filesystem content at startup
452 - journald: also get thread ID from client, plus thread name
453 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
454 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
455 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
456 - declare the local journal protocol stable in the wiki interface chart
457 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
458 - journald: when dropping msgs due to ratelimit make sure to write
459 "dropped %u messages" not only when we are about to print the next
460 message that works, but alraedy after a short tiemout
461 - check if we can make journalctl by default use --follow mode inside of less if called without args?
462 - maybe add API to send pairs of iovecs via sd_journal_send
463 - journal: when writing journal auto-rotate if time jumps backwards
464 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
465 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
466 and !FOOBAR for events without FOOBAR.
467 - journal: store timestamp of journal_file_set_offline() int he header,
468 so it is possible to display when the file was last synced.
469 - 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.
470 - journal: find a way to allow dropping history early, based on priority, other rules
471 - journal: When used on NFS, check payload hashes
472 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
473 - refuse taking lower-case variable names in sd_journal_send() and friends.
474 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
475 - journal: deal nicely with byte-by-byte copied files, especially regards header
476 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
477 - Replace utmp, wtmp, btmp, and lastlog completely with journal
478 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
479 - when a kernel driver logs in a tight loop, we should ratelimit that too.
480 - journald: optionally, log debug messages to /run but everything else to /var
481 - journald: when we drop syslog messages because the syslog socket is
482 full, make sure to write how many messages are lost as first thing
483 to syslog when it works again.
484 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
485 - change systemd-journal-flush into a service that stays around during
486 boot, and causes the journal to be moved back to /run on shutdown,
487 so that we do not keep /var busy. This needs to happen synchronously,
488 hence doing this via signals is not going to work.
489 - optionally support running journald from the command line for testing purposes in external projects
490 - journald: allow per-priority and per-service retention times when rotating/vacuuming
491 - journald: make use of uid-range.h to managed uid ranges to split
493 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
494 - improve journalctl performance by loading journal files
495 lazily. Encode just enough information in the file name, so that we
496 do not have to open it to know that it is not interesting for us, for
497 the most common operations.
498 - journal-or-kmsg is currently broken? See reverted
499 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
500 - man: document that corrupted journal files is nothing to act on
501 - systemd-journal-upload (or a new, related tool): allow pushing out
502 journal messages onto the network in BSD syslog protocol,
503 continuously. Default to some link-local IP mcast group, to make this
504 useful as a one-stop debugging tool.
505 - rework journald sigbus stuff to use mutex
506 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
507 services that run under their own user ids, and use User= (but only
508 in a world where userns is ubiquitous since otherwise we cannot
509 invoke those daemons on the host AND in a container anymore). Also,
510 if LimitNPROC= is used without User= we should warn and refuse
512 - journalctl --verify: don't show files that are currently being
513 written to as FAIL, but instead show that their are being written to.
514 - add journalctl -H that talks via ssh to a remote peer and passes through
516 - change journalctl -M to acquire fd to journal directory via machined, and
517 then operate on that via openat() instead of absolute paths
518 - add a version of --merge which also merges /var/log/journal/remote
519 - log accumulated resource usage after each service invocation
520 - journalctl: -m should access container journals directly by enumerating
521 them via machined, and also watch containers coming and going.
522 Benefit: nspawn --ephemeral would start working nicely with the journal.
523 - assign MESSAGE_ID to log messages about failed services
526 - document that deps in [Unit] sections ignore Alias= fields in
527 [Install] units of other units, unless those units are disabled
528 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
529 - document the exit codes when services fail before they are exec()ed
530 - document that service reload may be implemented as service reexec
531 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
532 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
533 - document systemd-journal-flush.service properly
534 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
535 - man: document the very specific env the shutdown drop-in tools live in
536 - man: add more examples to man pages
537 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
540 - systemctl list-jobs - show dependencies
541 - add systemctl switch to dump transaction without executing it
542 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
543 - "systemctl disable" on a static unit prints no message and does
544 nothing. "systemctl enable" does nothing, and gives a bad message
545 about it. Should fix both to print nice actionable messages.
546 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
547 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
548 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
549 - systemctl: "Journal has been rotated since unit was started." message is misleading
550 - better error message if you run systemctl without systemd running
551 - systemctl status output should should include list of triggering units and their status
554 - "systemctl mask" should find all names by which a unit is accessible
555 (i.e. by scanning for symlinks to it) and link them all to /dev/null
556 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
559 - timer units should get the ability to trigger when:
560 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
562 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
563 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
564 - Modulate timer frequency based on battery state
566 * add libsystemd-password or so to query passwords during boot using the password agent logic
568 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
570 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
572 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
573 waiting for the timeout
575 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
577 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
580 - to allow "linking" of nspawn containers, extend --network-bridge= so
581 that it can dynamically create bridge interfaces that are refcounted
582 by the containers on them. For each group of containers to link together
583 - refuses to boot containers without /etc/machine-id (OK?), and with empty
584 /etc/machine-id (not OK).
585 - nspawn -x should support ephemeral instances of gpt images
586 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
587 with seccomp. That should provide us with a useful log buffer that
588 systemd can log to during early boot, and disconnect container logs
589 from the kernel's logs.
590 - as soon as networkd has a bus interface, hook up --network-interface=,
591 --network-bridge= with networkd, to trigger netdev creation should an
593 - don't copy /etc/resolv.conf from host into container unless we are in
595 - a nice way to boot up without machine id set, so that it is set at boot
596 automatically for supporting --ephemeral. Maybe hash the host machine id
597 together with the machine name to generate the machine id for the container
598 - fix logic always print a final newline on output.
599 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
600 - should optionally support receiving WATCHDOG=1 messages from its payload
602 - should send out sd_notify("WATCHDOG=1") messages
603 - optionally automatically add FORWARD rules to iptables whenever nspawn is
604 running, remove them when shut down.
605 - add a logic for cleaning up read-only, hidden container images in
606 /var/lib/machines that are not ancestors of any non-hidden containers
607 - Improve error message when --bind= is used on a non-existing source
609 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
613 - "machinectl list" should probably show columns for OS version and IP
615 - add an API so that libvirt-lxc can inform us about network interfaces being
616 removed or added to an existing machine
617 - "machinectl migrate" or similar to copy a container from or to a
618 difference host, via ssh
619 - introduce systemd-nspawn-ephemeral@.service, and hook it into
620 "machinectl start" with a new --ephemeral switch
621 - "machinectl status" should also show internal logs of the container in
623 - "machinectl list-images" should show os-release data, as well as
624 machine-info data (including deployment level)
625 - "machinectl history"
627 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
628 shell in it, and marks it read-only after use
631 - generate a nice warning if mkfs.btrfs is missing
634 - cryptsetup-generator: allow specification of passwords in crypttab itself
635 - move cryptsetup key caching into kernel keyctl?
636 https://bugs.freedesktop.org/show_bug.cgi?id=54982
637 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
639 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
640 https://bugs.freedesktop.org/show_bug.cgi?id=54712
642 * create /sbin/init symlinks from the build system
644 * MountFlags=shared acts as MountFlags=slave right now.
646 * properly handle loop back mounts via fstab, especially regards to fsck/passno
648 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
650 * rename "userspace" to "core-os"
655 - add trigger --subsystem-match=usb/usb_device device
656 - reimport udev db after MOVE events for devices without dev_t
658 * 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
660 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
662 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
665 - save coredump in Windows/Mozilla minidump format
666 - move PID 1 segfaults to /var/lib/systemd/coredump?
667 - make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
668 and supress coredump if turned off. Then change RLIMIT_CORE to
669 infinity by default for all services. This then allows per-service
670 control of coredumping.
672 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
674 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
676 * be able to specify a forced restart of service A where service B depends on, in case B
677 needs to be auto-respawned?
680 - apply "x" on "D" too (see patch from William Douglas)
682 - instead of ignoring unknown fields, reject them.
683 - creating new directories/subvolumes/fifos/device nodes
684 should not follow symlinks. None of the other adjustment or creation
685 calls follow symlinks.
687 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
689 * verify that the AF_UNIX sockets of a service in the fs still exist
690 when we start a service in order to avoid confusion when a user
691 assumes starting a service is enough to make it accessible
693 * Make it possible to set the keymap independently from the font on
694 the kernel cmdline. Right now setting one resets also the other.
696 * and a dbus call to generate target from current state
698 * write blog stories about:
699 - hwdb: what belongs into it, lsusb
700 - enabling dbus services
702 - how to make changes to sysctl and sysfs attributes
704 - how to pass throw-away units to systemd, or dynamically change properties of existing units
705 - testing with Harald's awesome test kit
707 - how to develop against journal browsing APIs
708 - the journal HTTP iface
709 - non-cgroup resource management
710 - dynamic resource management with cgroups
711 - refreshed, longer missions statement
712 - calendar time events
713 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
714 - how to create your own target
715 - instantiated apache, dovecot and so on
716 - hooking a script into various stages of shutdown/rearly booot
718 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
720 * dot output for --test showing the 'initial transaction'
722 * fingerprint.target, wireless.target, gps.target, netdevice.target
725 - .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
726 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
727 log both units as UNIT=, so that journalctl -u triggers on both.
728 - generate better errors when people try to set transient properties
729 that are not supported...
730 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
731 - maybe introduce WantsMountsFor=? Usecase:
732 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
733 - recreate systemd's D-Bus private socket file on SIGUSR2
734 - GC unreferenced jobs (such as .device jobs)
735 - move PAM code into its own binary
736 - when we automatically restart a service, ensure we restart its rdeps, too.
737 - for services: do not set $HOME in services unless requested
738 - hide PAM options in fragment parser when compile time disabled
739 - Support --test based on current system state
740 - 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().
741 - after deserializing sockets in socket.c we should reapply sockopts and things
742 - drop PID 1 reloading, only do reexecing (difficult: Reload()
743 currently is properly synchronous, Reexec() is weird, because we
744 cannot delay the response properly until we are back, so instead of
745 being properly synchronous we just keep open the fd and close it
746 when done. That means clients do not get a successful method reply,
747 but much rather a disconnect on success.
748 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
749 - when a bus name of a service disappears from the bus make sure to queue further activation requests
752 - allow port=0 in .socket units
753 - maybe introduce ExecRestartPre=
754 - add ReloadSignal= for configuring a reload signal to use
755 - implement Register= switch in .socket units to enable registration
756 in Avahi, RPC and other socket registration services.
757 - allow Type=simple with PIDFile=
758 https://bugzilla.redhat.com/show_bug.cgi?id=723942
759 - allow writing multiple conditions in unit files on one line
760 - load-fragment: when loading a unit file via a chain of symlinks
761 verify that it is not masked via any of the names traversed.
762 - introduce Type=pid-file
763 - ExecOnFailure=/usr/bin/foo
764 - introduce mix of BindTo and Requisite
765 - add a concept of RemainAfterExit= to scope units
766 - Set NoNewPrivileges= on all of our own services, where that makes sense
767 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
768 - consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
771 - figure out a simple way to wait for journal events in a way that
773 - add documentation to systemd.daemon
776 - plot per-process IO utilization
777 - group processes based on service association (cgroups)
778 - document initcall_debug
779 - kernel cmdline "bootchart" option for simplicity?
782 - Make sure ID_PATH is always exported and complete for
783 network devices where possible, so we can safely rely
785 - check MTUBytes parsing (expecting size_t but we are using unsigned)
788 - add support for more attribute types
789 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
792 - add more keys to [Route] and [Address] sections
793 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
794 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
795 - add reduced [Link] support to .network files
796 - add Scope= parsing option for [Network]
797 - properly handle routerless dhcp leases
798 - add more attribute support for SIT tunnel
799 - work with non-Ethernet devices
800 - add support for more bond options
801 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
802 - add LLDP client side support
803 - the DHCP lease data (such as NTP/DNS) is still made available when
804 a carrier is lost on a link. It should be removed instantly.
805 - expose in the API the following bits:
806 - option 15, domain name and/or option 119, search list
807 - option 12, host name and/or option 81, fqdn
808 - option 123, 144, geolocation
809 - option 252, configure http proxy (PAC/wpad)
810 - provide a way to define a per-network interface default metric value
811 for all routes to it. possibly a second default for DHCP routes.
812 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
813 support Name=foo*|bar*|baz ?
814 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
815 - allow DUID/IAID to be customized, see issue #394.
816 - support configuration option for TSO (tcp segmentation offload)
817 - whenever uplink info changes, make DHCP server send out FORCERENEW
819 * networkd-wait-online:
820 - make operstates to wait for configurable?
823 - figure out how much we can increase Maximum Message Size
824 - support RFC4702 (pass FQDN)
827 - add functions to set previously stored IPv6 addresses on startup and get
828 them at shutdown; store them in client->ia_na
829 - write more test cases
830 - implement reconfigure support, see 5.3., 15.11. and 22.20.
831 - implement support for temporary adressess (IA_TA)
832 - implement dhcpv6 authentication
833 - investigate the usefulness of Confirm messages; i.e. are there any
834 situations where the link changes without any loss in carrier detection
836 - some servers don't do rapid commit without a filled in IA_NA, verify
842 - natively watch for dbus-*.service symlinks (PENDING)
843 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
845 * fix alsa mixer restore to not print error when no config is stored
847 * make cryptsetup lower --iter-time
849 * patch kernel for xattr support in /dev, /proc/, /sys?
851 * kernel: add device_type = "fb", "fbcon" to class "graphics"
853 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
855 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
857 * /usr/bin/service should actually show the new command line
859 * 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=
861 * fedora: F20: go timer units all the way, leave cron.daily for cron
863 * neither pkexec nor sudo initialize environ[] from the PAM environment?
865 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
867 * register catalog database signature as file magic
869 * zsh shell completion:
870 - <command> <verb> -<TAB> should complete options, but currently does not
871 - systemctl add-wants,add-requires
876 * look for close() vs. close_nointr() vs. close_nointr_nofail()
878 * check for strerror(r) instead of strerror(-r)
880 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
884 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
886 * use secure_getenv() instead of getenv() where appropriate
888 * link up selected blog stories from man pages and unit files Documentation= fields
