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 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
38 * maybe: pid1: replace cgroups agent transport by AF_UNIX/SOCK_DGRAM, so that
39 we aren't hit by socket backlog exhaustion on the dbus AF_UNIX/SOCK_STREAM
42 * journalctl: make sure -f ends when the container indicated by -M terminates
44 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
45 kernel doesn't support linkat() that replaces existing files, currently)
47 * check if DeviceAllow= should split first, resolve specifiers later
49 * transient units: don't bother with actually setting unit properties, we
50 reload the unit file anyway
52 * make sure resolved can be restarted without losing pushed-in dns config
54 * fix https://github.com/systemd/systemd/pull/2890, this shouldn't be exported
57 * journald: sigbus API via a signal-handler safe function that people may call
58 from the SIGBUS handler
60 * when using UTF8, ellipsize with "…" rather than "...", so that we can show more contents before truncating
62 * move specifier expansion from service_spawn() into load-fragment.c
64 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
66 * resolved: maybe, after all, implement local listening for DNS packets on port
69 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
70 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
72 * cache sd_event_now() result from before the first iteration...
74 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
76 * Maybe add a way how users can "pin" units into memory, so that they are not subject to automatic GC?
78 * PID1: find a way how we can reload unit file configuration for
79 specific units only, without reloading the whole of systemd
81 * add an explicit parser for LimitRTPRIO= that verifies
82 the specified range and generates sane error messages for incorrect
85 * do something about "/control" subcgroups in the unified cgroup hierarchy
87 * when we detect that there are waiting jobs but no running jobs, do something
89 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
91 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
93 * consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
95 * there's probably something wrong with having user mounts below /sys,
96 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
97 prefixed with /sys generally special.
98 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
100 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
102 * install: include generator dirs in unit file search paths
104 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
106 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
108 * mounting and unmounting mount points manually with different source
109 devices will result in collected collected on all devices used.
110 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
112 * add a job mode that will fail if a transaction would mean stopping
113 running units. Use this in timedated to manage the NTP service
115 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
117 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
118 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
120 * The udev blkid built-in should expose a property that reflects
121 whether media was sensed in USB CF/SD card readers. This should then
122 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
123 picked up by systemd unless they contain a medium. This would mirror
124 the behaviour we already have for CD drives.
126 * networkd/udev: implement SR_IOV configuration in .link files:
127 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
129 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
131 * implement a per-service firewall based on net_cls
133 * Port various tools to make use of verbs.[ch], where applicable
135 * hostnamectl: show root image uuid
137 * sysfs set api in libudev is not const
139 * Find a solution for SMACK capabilities stuff:
140 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
142 * "systemctl preset-all" should probably order the unit files it
143 operates on lexicographically before starting to work, in order to
144 ensure deterministic behaviour if two unit files conflict (like DMs
147 * synchronize console access with BSD locks:
148 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
150 * as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
151 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
153 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
155 * figure out when we can use the coarse timers
157 * add "systemctl start -v foobar.service" that shows logs of a service
158 while the start command runs. This is non-trivial to do without
159 races though, since we should flush out all journal messages before
160 returning from the "systemctl stop".
162 * 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
164 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
166 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
168 * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
170 * consider showing the unit names during boot up in the status output, not just the unit descriptions
172 * maybe allow timer units with an empty Units= setting, so that they
173 can be used for resuming the system but nothing else.
175 * what to do about udev db binary stability for apps? (raw access is not an option)
177 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
179 * man: maybe use the word "inspect" rather than "introspect"?
181 * systemctl: if some operation fails, show log output?
184 - allow creation of units from scratch
185 - use equvalent of cat() to insert existing config as a comment, prepended with #.
186 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
188 * exponential backoff in timesyncd when we cannot reach a server
190 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
192 * extract_many_words() should probably be used by a lot of code that
193 currently uses FOREACH_WORD and friends. For example, most conf
194 parsing callbacks should use it.
196 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
198 * systemd.show_status= should probably have a mode where only failed
201 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
202 (throughout the codebase, not only PID1)
206 - service registration
207 - service/domain/types browsing
209 - DNS-SD service registration from socket units
210 - resolved should optionally register additional per-interface LLMNR
211 names, so that for the container case we can establish the same name
212 (maybe "host") for referencing the server, everywhere.
213 - enable DNSSEC by default
214 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
216 * refcounting in sd-resolve is borked
218 * Add a new verb "systemctl top"
220 * add new gpt type for btrfs volumes
222 * support empty /etc boots nicely:
223 - nspawn/gpt-generator: introduce new gpt partition type for /usr
224 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
226 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
228 * a way for container managers to turn off getty starting via $container_headless= or so...
230 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
232 * mount_cgroup_controllers(): symlinks need to get the label applied
234 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
235 they run added to the initial transaction and thus confuse Type=idle.
237 * 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)
239 * add bus api to query unit file's X fields.
241 * gpt-auto-generator:
242 - Support LUKS for root devices
243 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
244 - Make /home automount rather than mount?
246 * add generator that pulls in systemd-network from containers when
247 CAP_NET_ADMIN is set, more than the loopback device is defined, even
248 when it is otherwise off
250 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
252 * "busctl status" works only as root on dbus1, since we cannot read
255 * implement Distribute= in socket units to allow running multiple
256 service instances processing the listening socket, and open this up
259 * socket units: support creating sockets in different namespace,
260 opening it up for JoinsNamespaceOf=. This would require to fork off
261 a tiny process that joins the namespace and creates/binds the socket
262 and passes this back to PID1 via SCM_RIGHTS. This also could be used
263 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
265 * New service property: maximum CPU runtime for a service
267 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
268 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
269 should SIGSTOP all unit processes in a loop until all processes of
270 it are fully stopped. This can later be used for app management by
271 desktop UIs such as gnome-shell to freeze apps that are not visible
272 on screen, not unlike how job control works on the shell
275 - implement per-slice CPUFairScheduling=1 switch
276 - handle jointly mounted controllers correctly
277 - introduce high-level settings for RT budget, swappiness
278 - how to reset dynamically changed unit cgroup attributes sanely?
279 - when reloading configuration, apply new cgroup configuration
280 - when recursively showing the cgroup hierarchy, optionally also show
281 the hierarchies of child processes
284 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
285 - ensure scope units may be started only a single time
287 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
289 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
291 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
293 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
295 * unify dispatch table in systemctl_main() and friends
297 * 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
299 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
301 * If we try to find a unit via a dangling symlink, generate a clean
302 error. Currently, we just ignore it and read the unit from the search
305 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
307 * btrfs raid assembly: some .device jobs stay stuck in the queue
309 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
311 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
313 * load .d/*.conf dropins for device units
315 * allow implementation of InaccessibleDirectories=/ plus
316 ReadOnlyDirectories=... for whitelisting files for a service.
320 - GetAllProperties() on a non-existing object does not result in a failure currently
321 - kdbus: process fd=-1 for incoming msgs
322 - port to sd-resolve for connecting to TCP dbus servers
323 - kdbus: maybe add controlling tty metadata fields
324 - 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
325 - when kdbus does not take our message without memfds, try again with memfds
326 - see if we can drop more message validation on the sending side
327 - add API to clone sd_bus_message objects
328 - make AddMatch calls on dbus1 transports async?
329 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
330 - longer term: priority inheritance
333 - NameLost/NameAcquired obsolete
336 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
337 - test bloom filter generation indexes
338 - kdbus: introduce a concept of "send-only" connections
339 - 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.
342 - allow multiple signal handlers per signal?
343 - document chaining of signal handler for SIGCHLD and child handlers
344 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
345 - generate a failure of a default event loop is executed out-of-thread
346 - maybe add support for inotify events
348 * investigate endianness issues of UUID vs. GUID
350 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
351 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
353 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
355 * add a pam module that on password changes updates any LUKS slot where the password matches
357 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
359 * cgtop: make cgtop useful in a container
362 - add 'set -e' to scripts in test/
363 - make stuff in test/ work with separate output dir
365 * seems that when we follow symlinks to units we prefer the symlink
366 destination path over /etc and /usr. We should not do that. Instead
367 /etc should always override /run+/usr and also any symlink
370 * when isolating, try to figure out a way how we implicitly can order
371 all units we stop before the isolating unit...
373 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
375 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
376 that the boot loader should be installed to the ESP. Define a way
377 how an installer can figure out whether a BLS compliant boot loader
380 * think about requeuing jobs when daemon-reload is issued? usecase:
381 the initrd issues a reload after fstab from the host is accessible
382 and we might want to requeue the mounts local-fs acquired through
385 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
387 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
389 * shutdown logging: store to EFI var, and store to USB stick?
391 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
393 * merge unit_kill_common() and unit_kill_context()
395 * introduce ExecCondition= in services
398 - honor language efi variables for default language selection (if there are any?)
399 - honor timezone efi variables for default timezone selection (if there are any?)
400 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
402 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
404 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
406 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
409 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
410 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
411 - logind: wakelock/opportunistic suspend support
412 - Add pretty name for seats in logind
413 - logind: allow showing logout dialog from system?
414 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
415 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
416 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
417 - if pam_systemd is invoked by su from a process that is outside of a
418 any session we should probably just become a NOP, since that's
419 usually not a real user session but just some system code that just
421 - logind: make the Suspend()/Hibernate() bus calls wait for the for
422 the job to be completed. before returning, so that clients can wait
423 for "systemctl suspend" to finish to know when the suspending is
425 - logind: when the power button is pressed short, just popup a
426 logout dialog. If it is pressed for 1s, do the usual
427 shutdown. Inspiration are Macs here.
428 - expose "Locked" property on logind sesison objects
429 - given that logind now lets PID 1 do all nasty work, we can
430 probably reduce the capability set it retains substantially.
431 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
432 - expose orientation sensors and tablet mode through logind
433 - maybe allow configuration of the StopTimeout for session scopes
434 - rename session scope so that it includes the UID. THat way
435 the session scope can be arranged freely in slices and we don't have
436 make assumptions about their slice anymore.
437 - follow PropertiesChanged state more closely, to deal with quick logouts and
440 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
442 * service: watchdog logic: for testing purposes allow ping, but do not require pong
445 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
446 - import and delete pstore filesystem content at startup
447 - journald: also get thread ID from client, plus thread name
448 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
449 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
450 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
451 - declare the local journal protocol stable in the wiki interface chart
452 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
453 - journald: when dropping msgs due to ratelimit make sure to write
454 "dropped %u messages" not only when we are about to print the next
455 message that works, but alraedy after a short tiemout
456 - check if we can make journalctl by default use --follow mode inside of less if called without args?
457 - maybe add API to send pairs of iovecs via sd_journal_send
458 - journal: when writing journal auto-rotate if time jumps backwards
459 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
460 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
461 and !FOOBAR for events without FOOBAR.
462 - journal: store timestamp of journal_file_set_offline() int he header,
463 so it is possible to display when the file was last synced.
464 - 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.
465 - journal: find a way to allow dropping history early, based on priority, other rules
466 - journal: When used on NFS, check payload hashes
467 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
468 - refuse taking lower-case variable names in sd_journal_send() and friends.
469 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
470 - journal: deal nicely with byte-by-byte copied files, especially regards header
471 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
472 - Replace utmp, wtmp, btmp, and lastlog completely with journal
473 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
474 - when a kernel driver logs in a tight loop, we should ratelimit that too.
475 - journald: optionally, log debug messages to /run but everything else to /var
476 - journald: when we drop syslog messages because the syslog socket is
477 full, make sure to write how many messages are lost as first thing
478 to syslog when it works again.
479 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
480 - change systemd-journal-flush into a service that stays around during
481 boot, and causes the journal to be moved back to /run on shutdown,
482 so that we do not keep /var busy. This needs to happen synchronously,
483 hence doing this via signals is not going to work.
484 - optionally support running journald from the command line for testing purposes in external projects
485 - journald: allow per-priority and per-service retention times when rotating/vacuuming
486 - journald: make use of uid-range.h to managed uid ranges to split
488 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
489 - improve journalctl performance by loading journal files
490 lazily. Encode just enough information in the file name, so that we
491 do not have to open it to know that it is not interesting for us, for
492 the most common operations.
493 - journal-or-kmsg is currently broken? See reverted
494 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
495 - man: document that corrupted journal files is nothing to act on
496 - rework journald sigbus stuff to use mutex
497 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
498 services that run under their own user ids, and use User= (but only
499 in a world where userns is ubiquitous since otherwise we cannot
500 invoke those daemons on the host AND in a container anymore). Also,
501 if LimitNPROC= is used without User= we should warn and refuse
503 - journalctl --verify: don't show files that are currently being
504 written to as FAIL, but instead show that their are being written to.
505 - add journalctl -H that talks via ssh to a remote peer and passes through
507 - add a version of --merge which also merges /var/log/journal/remote
508 - log accumulated resource usage after each service invocation
509 - journalctl: -m should access container journals directly by enumerating
510 them via machined, and also watch containers coming and going.
511 Benefit: nspawn --ephemeral would start working nicely with the journal.
512 - assign MESSAGE_ID to log messages about failed services
515 - document that deps in [Unit] sections ignore Alias= fields in
516 [Install] units of other units, unless those units are disabled
517 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
518 - document the exit codes when services fail before they are exec()ed
519 - document that service reload may be implemented as service reexec
520 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
521 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
522 - document systemd-journal-flush.service properly
523 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
524 - man: document the very specific env the shutdown drop-in tools live in
525 - man: add more examples to man pages
526 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
529 - systemctl list-jobs - show dependencies
530 - add systemctl switch to dump transaction without executing it
531 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
532 - "systemctl disable" on a static unit prints no message and does
533 nothing. "systemctl enable" does nothing, and gives a bad message
534 about it. Should fix both to print nice actionable messages.
535 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
536 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
537 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
538 - systemctl: "Journal has been rotated since unit was started." message is misleading
539 - better error message if you run systemctl without systemd running
540 - systemctl status output should should include list of triggering units and their status
543 - "systemctl mask" should find all names by which a unit is accessible
544 (i.e. by scanning for symlinks to it) and link them all to /dev/null
547 - timer units should get the ability to trigger when:
548 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
550 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
551 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
552 - Modulate timer frequency based on battery state
554 * add libsystemd-password or so to query passwords during boot using the password agent logic
556 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
558 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
560 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
561 waiting for the timeout
563 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
565 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
568 - to allow "linking" of nspawn containers, extend --network-bridge= so
569 that it can dynamically create bridge interfaces that are refcounted
570 by the containers on them. For each group of containers to link together
571 - nspawn -x should support ephemeral instances of gpt images
572 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
573 with seccomp. That should provide us with a useful log buffer that
574 systemd can log to during early boot, and disconnect container logs
575 from the kernel's logs.
576 - as soon as networkd has a bus interface, hook up --network-interface=,
577 --network-bridge= with networkd, to trigger netdev creation should an
579 - don't copy /etc/resolv.conf from host into container unless we are in
581 - a nice way to boot up without machine id set, so that it is set at boot
582 automatically for supporting --ephemeral. Maybe hash the host machine id
583 together with the machine name to generate the machine id for the container
584 - fix logic always print a final newline on output.
585 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
586 - should optionally support receiving WATCHDOG=1 messages from its payload
588 - should send out sd_notify("WATCHDOG=1") messages
589 - optionally automatically add FORWARD rules to iptables whenever nspawn is
590 running, remove them when shut down.
591 - Improve error message when --bind= is used on a non-existing source
593 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
597 - "machinectl list" should probably show columns for OS version and IP
599 - add an API so that libvirt-lxc can inform us about network interfaces being
600 removed or added to an existing machine
601 - "machinectl migrate" or similar to copy a container from or to a
602 difference host, via ssh
603 - introduce systemd-nspawn-ephemeral@.service, and hook it into
604 "machinectl start" with a new --ephemeral switch
605 - "machinectl status" should also show internal logs of the container in
607 - "machinectl list-images" should show os-release data, as well as
608 machine-info data (including deployment level)
609 - "machinectl history"
611 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
612 shell in it, and marks it read-only after use
615 - generate a nice warning if mkfs.btrfs is missing
618 - cryptsetup-generator: allow specification of passwords in crypttab itself
619 - move cryptsetup key caching into kernel keyctl?
620 https://bugs.freedesktop.org/show_bug.cgi?id=54982
621 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
623 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
624 https://bugs.freedesktop.org/show_bug.cgi?id=54712
626 * create /sbin/init symlinks from the build system
628 * MountFlags=shared acts as MountFlags=slave right now.
630 * properly handle loop back mounts via fstab, especially regards to fsck/passno
632 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
637 - add trigger --subsystem-match=usb/usb_device device
638 - reimport udev db after MOVE events for devices without dev_t
640 * 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
642 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
644 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
647 - save coredump in Windows/Mozilla minidump format
648 - move PID 1 segfaults to /var/lib/systemd/coredump?
650 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
652 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
654 * be able to specify a forced restart of service A where service B depends on, in case B
655 needs to be auto-respawned?
658 - apply "x" on "D" too (see patch from William Douglas)
660 - instead of ignoring unknown fields, reject them.
661 - creating new directories/subvolumes/fifos/device nodes
662 should not follow symlinks. None of the other adjustment or creation
663 calls follow symlinks.
665 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
667 * verify that the AF_UNIX sockets of a service in the fs still exist
668 when we start a service in order to avoid confusion when a user
669 assumes starting a service is enough to make it accessible
671 * Make it possible to set the keymap independently from the font on
672 the kernel cmdline. Right now setting one resets also the other.
674 * and a dbus call to generate target from current state
676 * write blog stories about:
677 - hwdb: what belongs into it, lsusb
678 - enabling dbus services
680 - how to make changes to sysctl and sysfs attributes
682 - how to pass throw-away units to systemd, or dynamically change properties of existing units
683 - testing with Harald's awesome test kit
685 - how to develop against journal browsing APIs
686 - the journal HTTP iface
687 - non-cgroup resource management
688 - dynamic resource management with cgroups
689 - refreshed, longer missions statement
690 - calendar time events
691 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
692 - how to create your own target
693 - instantiated apache, dovecot and so on
694 - hooking a script into various stages of shutdown/rearly booot
696 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
698 * dot output for --test showing the 'initial transaction'
700 * fingerprint.target, wireless.target, gps.target, netdevice.target
703 - .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
704 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
705 log both units as UNIT=, so that journalctl -u triggers on both.
706 - generate better errors when people try to set transient properties
707 that are not supported...
708 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
709 - maybe introduce WantsMountsFor=? Usecase:
710 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
711 - recreate systemd's D-Bus private socket file on SIGUSR2
712 - GC unreferenced jobs (such as .device jobs)
713 - move PAM code into its own binary
714 - when we automatically restart a service, ensure we restart its rdeps, too.
715 - for services: do not set $HOME in services unless requested
716 - hide PAM options in fragment parser when compile time disabled
717 - Support --test based on current system state
718 - 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().
719 - after deserializing sockets in socket.c we should reapply sockopts and things
720 - drop PID 1 reloading, only do reexecing (difficult: Reload()
721 currently is properly synchronous, Reexec() is weird, because we
722 cannot delay the response properly until we are back, so instead of
723 being properly synchronous we just keep open the fd and close it
724 when done. That means clients do not get a successful method reply,
725 but much rather a disconnect on success.
726 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
727 - when a bus name of a service disappears from the bus make sure to queue further activation requests
730 - allow port=0 in .socket units
731 - maybe introduce ExecRestartPre=
732 - add ReloadSignal= for configuring a reload signal to use
733 - implement Register= switch in .socket units to enable registration
734 in Avahi, RPC and other socket registration services.
735 - allow Type=simple with PIDFile=
736 https://bugzilla.redhat.com/show_bug.cgi?id=723942
737 - allow writing multiple conditions in unit files on one line
738 - load-fragment: when loading a unit file via a chain of symlinks
739 verify that it is not masked via any of the names traversed.
740 - introduce Type=pid-file
741 - ExecOnFailure=/usr/bin/foo
742 - introduce mix of BindTo and Requisite
743 - add a concept of RemainAfterExit= to scope units
744 - Set NoNewPrivileges= on all of our own services, where that makes sense
745 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
746 - consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
749 - Make sure ID_PATH is always exported and complete for
750 network devices where possible, so we can safely rely
752 - check MTUBytes parsing (expecting size_t but we are using unsigned)
755 - add support for more attribute types
756 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
759 - add more keys to [Route] and [Address] sections
760 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
761 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
762 - add reduced [Link] support to .network files
763 - add Scope= parsing option for [Network]
764 - properly handle routerless dhcp leases
765 - add more attribute support for SIT tunnel
766 - work with non-Ethernet devices
767 - add support for more bond options
768 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
769 - the DHCP lease data (such as NTP/DNS) is still made available when
770 a carrier is lost on a link. It should be removed instantly.
771 - expose in the API the following bits:
772 - option 15, domain name and/or option 119, search list
773 - option 12, host name and/or option 81, fqdn
774 - option 123, 144, geolocation
775 - option 252, configure http proxy (PAC/wpad)
776 - provide a way to define a per-network interface default metric value
777 for all routes to it. possibly a second default for DHCP routes.
778 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
779 support Name=foo*|bar*|baz ?
780 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
781 - allow DUID/IAID to be customized, see issue #394.
782 - support configuration option for TSO (tcp segmentation offload)
783 - whenever uplink info changes, make DHCP server send out FORCERENEW
785 * networkd-wait-online:
786 - make operstates to wait for configurable?
789 - figure out how much we can increase Maximum Message Size
790 - support RFC4702 (pass FQDN)
793 - add functions to set previously stored IPv6 addresses on startup and get
794 them at shutdown; store them in client->ia_na
795 - write more test cases
796 - implement reconfigure support, see 5.3., 15.11. and 22.20.
797 - implement support for temporary adressess (IA_TA)
798 - implement dhcpv6 authentication
799 - investigate the usefulness of Confirm messages; i.e. are there any
800 situations where the link changes without any loss in carrier detection
802 - some servers don't do rapid commit without a filled in IA_NA, verify
808 - natively watch for dbus-*.service symlinks (PENDING)
809 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
811 * fix alsa mixer restore to not print error when no config is stored
813 * make cryptsetup lower --iter-time
815 * patch kernel for xattr support in /dev, /proc/, /sys?
817 * kernel: add device_type = "fb", "fbcon" to class "graphics"
819 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
821 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
823 * /usr/bin/service should actually show the new command line
825 * 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=
827 * fedora: F20: go timer units all the way, leave cron.daily for cron
829 * neither pkexec nor sudo initialize environ[] from the PAM environment?
831 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
833 * register catalog database signature as file magic
835 * zsh shell completion:
836 - <command> <verb> -<TAB> should complete options, but currently does not
837 - systemctl add-wants,add-requires
842 * look for close() vs. close_nointr() vs. close_nointr_nofail()
844 * check for strerror(r) instead of strerror(-r)
846 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
850 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
852 * use secure_getenv() instead of getenv() where appropriate
854 * link up selected blog stories from man pages and unit files Documentation= fields
