3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
19 * wiki: update journal format documentation for lz4 additions
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
27 * make use of ethtool veth peer info in machined, for automatically finding out
28 host-side interface pointing to the container.
30 * add some special mode to LogsDirectory=/StateDirectory=… that allows
31 declaring these directories without necessarily pulling in deps for them, or
32 creating them when starting up. That way, we could declare that
33 systemd-journald writes to /var/log/journal, which could be useful when we
34 doing disk usage calculations and so on.
36 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
37 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
38 as the unit is running or has a job queued.
40 * hook up sd-bus' creds stuff with SO_PEERGROUPS
42 * add async version of sd_bus_add_match and make use of that
44 * support projid-based quota in machinectl for containers, and then drop
45 implicit btrfs loopback magic in machined
47 * let's log the "tainted" string at boot
49 * Add NetworkNamespacePath= to specify a path to a network namespace
51 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
52 introduced) as the RTC epoch, instead of the mtime of NEWS.
54 * add a way to lock down cgroup migration: a boolean, which when set for a unit
55 makes sure the processes in it can never migrate out of it
57 * blog about fd store and restartable services
59 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
61 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
62 magic meaning and is no longer upgraded to something else if set explicitly.
64 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
65 make it lose its identity, i.e. be anonymous. For this we'd have to patch
66 through the whole tree to make all code deal with the case where no machine
69 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
70 suitable for processing with rrdtool. Add bus API to access this data, and
71 possibly implement a CPULoad property based on it.
73 * In journalctl add a way how "-o verbose" and suchlike can be tweaked to show
74 only a specific set of properties
76 * beef up pam_systemd to take unit file settings such as cgroups properties as
79 * export UID ranges nspawns's --private-user and DynamicUser= uses in
80 the systemd.pc pkg-config file, the same way we already expose the system
83 * a new "systemd-analyze security" tool outputting a checklist of security
84 features a service does and does not implement
86 * Whenever we check a UID against the system UID range, also check for the
89 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
90 the quota of a the user indicated in User= via unit file settings, like the
91 other resource management concepts. Would mix nicely with DynamicUser=1. Or
92 alternatively, do this with projids, so that we can also cover services
93 running as root. Quota should probably cover all the special dirs such as
94 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
95 is set, plus the whole disk space any image configured with RootImage=.
97 * Introduce "exit" as an EmergencyAction value, and allow to configure a
98 per-unit success/failure exit code to configure. This would be useful for
99 running commands inside of services inside of containers, which could then
100 propagate their failure state all the way up.
102 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
103 disks to see if the UID is already in use.
105 * add dissect_image_warn() as a wrapper around dissect_image() that prints
106 friendly log messages for the returned errors, so that we don't have to
107 duplicate that in nspawn, systemd-dissect and PID 1.
109 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
110 for all units. It should be both a way to pin units into memory as well as a
111 wait to retrieve their exit data.
113 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
114 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
115 automatically. For example, there could be $RUNTIME_DIRECTORY,
116 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
117 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
118 can adapt to varying directories for these purposes. Special care has to be
119 taken if multiple dirs are configured. Maybe avoid setting the env vars in
122 * introduce SuccessAction= that permits shutting down the system when a service
123 succeeds. This is useful to replace "ExecPost=/usr/bin/systemctl poweroff" and
124 similar constructs, which are frequently used. This is particularly nice for
125 implementation of a systemd.run= kernel command line option that runs some
126 command and immediately shuts down.
128 * expose IO accounting data on the bus, show it in systemd-run --wait and log
129 about it in the resource log message
131 * rework unbase64 code to drop whitespace automatically, so that we don't have
134 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
135 unit when it is stopped
137 * show whether a service has out-of-date configuration in "systemctl status" by
138 using mtime data of ConfigurationDirectory=.
140 * replace all uses of fgets() + LINE_MAX by read_line()
142 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
143 creates a static, persistent user rather than a dynamic, transient user. We
144 can leverage code from sysusers.d for this.
146 * add some optional flag to ReadWritePaths= and friends, that has the effect
147 that we create the dir in question when the service is started. Example:
149 ReadWritePaths=:/var/lib/foobar
151 * sort generated hwdb files alphabetically when we import them, so that git
152 diffs remain minimal (in particular: the OUI databases we import are not
153 sorted, and not stable)
155 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
156 the sd-journal logging socket, and, if the timeout is set to 0, sets
157 O_NONBLOCK on it. That way people can control if and when to block for
160 * tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
161 PIDs not managed by the service manager)
163 * hostnamed: populate form factor data from a new hwdb database, so that old
164 yogas can be recognized as "convertible" too, even if they predate the DMI
165 "convertible" form factor
167 * Maybe add a small tool invoked early at boot, that adds in or resizes
168 partitions automatically, to be used when the media used is actually larger
169 than the image written onto it is.
171 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
172 after all. Be strict however, only support the equivalent of nspawn's
173 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
176 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
177 the service cgroup, which is supposed to monitor the service, and when it
178 exits the service is considered failed by its monitor.
180 * track the per-service PAM process properly (i.e. as an additional control
181 process), so that it may be queried on the bus and everything.
183 * add a new "debug" job mode, that is propagated to unit_start() and for
184 services results in two things: we raise SIGSTOP right before invoking
185 execve() and turn off watchdog support. Then, use that to implement
186 "systemd-gdb" for attaching to the start-up of any system service in its
189 * replace all canonicalize_file_name() invocations by chase_symlinks(), in
190 particulr those where a rootdir is relevant.
192 * maybe introduce gpt auto discovery for /var/tmp?
194 * maybe add gpt-partition-based user management: each user gets his own
195 LUKS-encrypted GPT partition with a new GPT type. A small nss module
196 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
197 way: the partition index is added as offset to some fixed base uid. User name
198 is stored in GPT partition name. A PAM module authenticates the user via the
199 LUKS partition password. Benefits: strong per-user security, compatibility
200 with stateless/read-only/verity-enabled root. (other idea: do this based on
201 loopback files in /home, without GPT involvement)
203 * gpt-auto logic: introduce support for discovering /var matching an image. For
204 that, use a partition type UUID that is hashed from the OS name (as encoded
205 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
206 field of the root partition. This way can easily support multiple OS
207 installations on the same GPT partition table, without problems with
208 unmatched /var partitions.
210 * gpt-auto logic: related to the above, maybe support a "secondary" root
211 partition, that is mounted to / and is writable, and where the actual root's
212 /usr is mounted into.
214 * machined: add apis to query /etc/machine-info data of a container
216 * .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly
218 * gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
220 * drop nss-myhostname in favour of nss-resolve?
222 * drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the
223 external nsswitch.conf based one
225 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
226 then use that for the setting used in user@.service. It should be understood
227 relative to the configured default value.
229 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
231 * enable LockMLOCK to take a percentage value relative to physical memory
233 * Permit masking specific netlink APIs with RestrictAddressFamily=
235 * nspawn: start UID allocation loop from hash of container name
237 * nspawn: support that /proc, /sys/, /dev are pre-mounted
239 * define gpt header bits to select volatility mode
241 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
243 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
245 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
247 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
249 * ProtectKeyRing= to take keyring calls away
251 * RemoveKeyRing= to remove all keyring entries of the specified user
253 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
254 on PID 1 with the relevant signals, and makes relevant files in /sys and
255 /proc (such as the sysrq stuff) unavailable
257 * DeviceAllow= should also generate seccomp filters for mknod()
259 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
261 * journalctl: make sure -f ends when the container indicated by -M terminates
263 * mount: automatically search for "main" partition of an image has multiple
266 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
269 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
270 find a way to map the User=/Group= of the service to the right name. This way
271 a user/group for a service only has to exist on the host for the right
274 * allow attaching additional journald log fields to cgroups
276 * add bus API for creating unit files in /etc, reusing the code for transient units
278 * add bus API to remove unit files from /etc
280 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
282 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
283 kernel doesn't support linkat() that replaces existing files, currently)
285 * check if DeviceAllow= should split first, resolve specifiers later
287 * transient units: don't bother with actually setting unit properties, we
288 reload the unit file anyway
290 * journald: sigbus API via a signal-handler safe function that people may call
291 from the SIGBUS handler
293 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
295 * resolved: when routing queries, make sure only look for the *longest* suffix...
297 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
298 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
300 * cache sd_event_now() result from before the first iteration...
302 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
304 * PID1: find a way how we can reload unit file configuration for
305 specific units only, without reloading the whole of systemd
307 * add an explicit parser for LimitRTPRIO= that verifies
308 the specified range and generates sane error messages for incorrect
311 * when we detect that there are waiting jobs but no running jobs, do something
313 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
315 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
317 * there's probably something wrong with having user mounts below /sys,
318 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
319 prefixed with /sys generally special.
320 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
322 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
324 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
326 * mounting and unmounting mount points manually with different source
327 devices will result in collected on all devices used.
328 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
330 * add a job mode that will fail if a transaction would mean stopping
331 running units. Use this in timedated to manage the NTP service
333 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
335 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
336 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
338 * The udev blkid built-in should expose a property that reflects
339 whether media was sensed in USB CF/SD card readers. This should then
340 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
341 picked up by systemd unless they contain a medium. This would mirror
342 the behaviour we already have for CD drives.
344 * networkd/udev: implement SR_IOV configuration in .link files:
345 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
347 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
349 * Port various tools to make use of verbs.[ch], where applicable: busctl,
350 coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
352 * hostnamectl: show root image uuid
354 * sysfs set api in libudev is not const
356 * Find a solution for SMACK capabilities stuff:
357 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
359 * "systemctl preset-all" should probably order the unit files it
360 operates on lexicographically before starting to work, in order to
361 ensure deterministic behaviour if two unit files conflict (like DMs
364 * synchronize console access with BSD locks:
365 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
367 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
368 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
370 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
372 * figure out when we can use the coarse timers
374 * add "systemctl start -v foobar.service" that shows logs of a service
375 while the start command runs. This is non-trivial to do without
376 races though, since we should flush out all journal messages before
377 returning from the "systemctl stop".
379 * 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
381 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
383 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
385 * consider showing the unit names during boot up in the status output, not just the unit descriptions
387 * maybe allow timer units with an empty Units= setting, so that they
388 can be used for resuming the system but nothing else.
390 * what to do about udev db binary stability for apps? (raw access is not an option)
392 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
394 * man: maybe use the word "inspect" rather than "introspect"?
396 * systemctl: if some operation fails, show log output?
398 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
399 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
401 * exponential backoff in timesyncd when we cannot reach a server
403 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
405 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
407 * systemd.show_status= should probably have a mode where only failed
410 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
411 (throughout the codebase, not only PID1)
415 - service registration
416 - service/domain/types browsing
418 - DNS-SD service registration from socket units
419 - resolved should optionally register additional per-interface LLMNR
420 names, so that for the container case we can establish the same name
421 (maybe "host") for referencing the server, everywhere.
422 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
423 - hook up resolved with machined-based address resolution
425 * refcounting in sd-resolve is borked
427 * Add a new verb "systemctl top"
429 * add new gpt type for btrfs volumes
431 * support empty /etc boots nicely:
432 - nspawn/gpt-generator: introduce new gpt partition type for /usr
434 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
436 * a way for container managers to turn off getty starting via $container_headless= or so...
438 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
440 * mount_cgroup_controllers(): symlinks need to get the label applied
442 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
443 they run added to the initial transaction and thus confuse Type=idle.
445 * add bus api to query unit file's X fields.
447 * gpt-auto-generator:
448 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
449 - Make /home automount rather than mount?
451 * add generator that pulls in systemd-network from containers when
452 CAP_NET_ADMIN is set, more than the loopback device is defined, even
453 when it is otherwise off
455 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
457 * implement Distribute= in socket units to allow running multiple
458 service instances processing the listening socket, and open this up
461 * socket units: support creating sockets in different namespace,
462 opening it up for JoinsNamespaceOf=. This would require to fork off
463 a tiny process that joins the namespace and creates/binds the socket
464 and passes this back to PID1 via SCM_RIGHTS. This also could be used
465 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
467 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
468 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
469 should SIGSTOP all unit processes in a loop until all processes of
470 it are fully stopped. This can later be used for app management by
471 desktop UIs such as gnome-shell to freeze apps that are not visible
472 on screen, not unlike how job control works on the shell
475 - implement per-slice CPUFairScheduling=1 switch
476 - handle jointly mounted controllers correctly
477 - introduce high-level settings for RT budget, swappiness
478 - how to reset dynamically changed unit cgroup attributes sanely?
479 - when reloading configuration, apply new cgroup configuration
480 - when recursively showing the cgroup hierarchy, optionally also show
481 the hierarchies of child processes
484 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
485 - ensure scope units may be started only a single time
487 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
489 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
491 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
493 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
495 * 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
497 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
499 * If we try to find a unit via a dangling symlink, generate a clean
500 error. Currently, we just ignore it and read the unit from the search
503 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
505 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
507 * load .d/*.conf dropins for device units
509 * allow implementation of InaccessibleDirectories=/ plus
510 ReadOnlyDirectories=... for whitelisting files for a service.
514 - GetAllProperties() on a non-existing object does not result in a failure currently
515 - port to sd-resolve for connecting to TCP dbus servers
516 - 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
517 - see if we can drop more message validation on the sending side
518 - add API to clone sd_bus_message objects
519 - make AddMatch calls on dbus1 transports async?
520 - longer term: priority inheritance
522 - NameLost/NameAcquired obsolete
525 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
526 - test bloom filter generation indexes
529 - allow multiple signal handlers per signal?
530 - document chaining of signal handler for SIGCHLD and child handlers
531 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
532 - generate a failure of a default event loop is executed out-of-thread
533 - maybe add support for inotify events
535 * investigate endianness issues of UUID vs. GUID
537 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
538 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
540 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
542 * add a pam module that on password changes updates any LUKS slot where the password matches
544 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
547 - add 'set -e' to scripts in test/
548 - make stuff in test/ work with separate output dir
550 * seems that when we follow symlinks to units we prefer the symlink
551 destination path over /etc and /usr. We should not do that. Instead
552 /etc should always override /run+/usr and also any symlink
555 * when isolating, try to figure out a way how we implicitly can order
556 all units we stop before the isolating unit...
558 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
560 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
561 that the boot loader should be installed to the ESP. Define a way
562 how an installer can figure out whether a BLS compliant boot loader
565 * think about requeuing jobs when daemon-reload is issued? usecase:
566 the initrd issues a reload after fstab from the host is accessible
567 and we might want to requeue the mounts local-fs acquired through
570 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
572 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
574 * shutdown logging: store to EFI var, and store to USB stick?
576 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
578 * merge unit_kill_common() and unit_kill_context()
580 * introduce ExecCondition= in services
583 - honor language efi variables for default language selection (if there are any?)
584 - honor timezone efi variables for default timezone selection (if there are any?)
585 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
587 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
589 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
591 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
594 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
595 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
596 - logind: wakelock/opportunistic suspend support
597 - Add pretty name for seats in logind
598 - logind: allow showing logout dialog from system?
599 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
600 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
601 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
602 - if pam_systemd is invoked by su from a process that is outside of a
603 any session we should probably just become a NOP, since that's
604 usually not a real user session but just some system code that just
606 - logind: make the Suspend()/Hibernate() bus calls wait for the for
607 the job to be completed. before returning, so that clients can wait
608 for "systemctl suspend" to finish to know when the suspending is
610 - logind: when the power button is pressed short, just popup a
611 logout dialog. If it is pressed for 1s, do the usual
612 shutdown. Inspiration are Macs here.
613 - expose "Locked" property on logind sesison objects
614 - given that logind now lets PID 1 do all nasty work, we can
615 probably reduce the capability set it retains substantially.
616 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
617 - expose orientation sensors and tablet mode through logind
618 - maybe allow configuration of the StopTimeout for session scopes
619 - rename session scope so that it includes the UID. THat way
620 the session scope can be arranged freely in slices and we don't have
621 make assumptions about their slice anymore.
622 - follow PropertiesChanged state more closely, to deal with quick logouts and
625 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
627 * service: watchdog logic: for testing purposes allow ping, but do not require pong
630 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
631 - import and delete pstore filesystem content at startup
632 - journald: also get thread ID from client, plus thread name
633 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
634 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
635 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
636 - declare the local journal protocol stable in the wiki interface chart
637 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
638 - journald: when dropping msgs due to ratelimit make sure to write
639 "dropped %u messages" not only when we are about to print the next
640 message that works, but alraedy after a short tiemout
641 - check if we can make journalctl by default use --follow mode inside of less if called without args?
642 - maybe add API to send pairs of iovecs via sd_journal_send
643 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
644 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
645 and !FOOBAR for events without FOOBAR.
646 - journal: store timestamp of journal_file_set_offline() int he header,
647 so it is possible to display when the file was last synced.
648 - 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.
649 - journal: find a way to allow dropping history early, based on priority, other rules
650 - journal: When used on NFS, check payload hashes
651 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
652 - refuse taking lower-case variable names in sd_journal_send() and friends.
653 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
654 - journal: deal nicely with byte-by-byte copied files, especially regards header
655 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
656 - Replace utmp, wtmp, btmp, and lastlog completely with journal
657 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
658 - when a kernel driver logs in a tight loop, we should ratelimit that too.
659 - journald: optionally, log debug messages to /run but everything else to /var
660 - journald: when we drop syslog messages because the syslog socket is
661 full, make sure to write how many messages are lost as first thing
662 to syslog when it works again.
663 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
664 - change systemd-journal-flush into a service that stays around during
665 boot, and causes the journal to be moved back to /run on shutdown,
666 so that we do not keep /var busy. This needs to happen synchronously,
667 hence doing this via signals is not going to work.
668 - optionally support running journald from the command line for testing purposes in external projects
669 - journald: allow per-priority and per-service retention times when rotating/vacuuming
670 - journald: make use of uid-range.h to managed uid ranges to split
672 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
673 - improve journalctl performance by loading journal files
674 lazily. Encode just enough information in the file name, so that we
675 do not have to open it to know that it is not interesting for us, for
676 the most common operations.
677 - journal-or-kmsg is currently broken? See reverted
678 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
679 - man: document that corrupted journal files is nothing to act on
680 - rework journald sigbus stuff to use mutex
681 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
682 services that run under their own user ids, and use User= (but only
683 in a world where userns is ubiquitous since otherwise we cannot
684 invoke those daemons on the host AND in a container anymore). Also,
685 if LimitNPROC= is used without User= we should warn and refuse
687 - journalctl --verify: don't show files that are currently being
688 written to as FAIL, but instead show that their are being written to.
689 - add journalctl -H that talks via ssh to a remote peer and passes through
691 - add a version of --merge which also merges /var/log/journal/remote
692 - log accumulated resource usage after each service invocation
693 - journalctl: -m should access container journals directly by enumerating
694 them via machined, and also watch containers coming and going.
695 Benefit: nspawn --ephemeral would start working nicely with the journal.
696 - assign MESSAGE_ID to log messages about failed services
699 - document that deps in [Unit] sections ignore Alias= fields in
700 [Install] units of other units, unless those units are disabled
701 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
702 - document that service reload may be implemented as service reexec
703 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
704 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
705 - document systemd-journal-flush.service properly
706 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
707 - man: document the very specific env the shutdown drop-in tools live in
708 - man: add more examples to man pages
709 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
712 - add systemctl switch to dump transaction without executing it
713 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
714 - "systemctl disable" on a static unit prints no message and does
715 nothing. "systemctl enable" does nothing, and gives a bad message
716 about it. Should fix both to print nice actionable messages.
717 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
718 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
719 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
720 - systemctl: "Journal has been rotated since unit was started." message is misleading
721 - better error message if you run systemctl without systemd running
722 - systemctl status output should include list of triggering units and their status
725 - "systemctl mask" should find all names by which a unit is accessible
726 (i.e. by scanning for symlinks to it) and link them all to /dev/null
729 - timer units should get the ability to trigger when:
730 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
732 - Modulate timer frequency based on battery state
734 * add libsystemd-password or so to query passwords during boot using the password agent logic
736 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
738 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
740 * make repeated alt-ctrl-del presses printing a dump
742 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
744 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
747 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
748 with seccomp. That should provide us with a useful log buffer that
749 systemd can log to during early boot, and disconnect container logs
750 from the kernel's logs.
751 - as soon as networkd has a bus interface, hook up --network-interface=,
752 --network-bridge= with networkd, to trigger netdev creation should an
754 - a nice way to boot up without machine id set, so that it is set at boot
755 automatically for supporting --ephemeral. Maybe hash the host machine id
756 together with the machine name to generate the machine id for the container
757 - fix logic always print a final newline on output.
758 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
759 - should optionally support receiving WATCHDOG=1 messages from its payload
761 - should send out sd_notify("WATCHDOG=1") messages
762 - optionally automatically add FORWARD rules to iptables whenever nspawn is
763 running, remove them when shut down.
764 - Improve error message when --bind= is used on a non-existing source
766 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
770 - refuse mounting over a mount point
771 - automatically discover .roothash files in dissect, similarly to nspawn
774 - add an API so that libvirt-lxc can inform us about network interfaces being
775 removed or added to an existing machine
776 - "machinectl migrate" or similar to copy a container from or to a
777 difference host, via ssh
778 - introduce systemd-nspawn-ephemeral@.service, and hook it into
779 "machinectl start" with a new --ephemeral switch
780 - "machinectl status" should also show internal logs of the container in
782 - "machinectl list-images" should show os-release data, as well as
783 machine-info data (including deployment level)
784 - "machinectl history"
786 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
787 shell in it, and marks it read-only after use
790 - generate a nice warning if mkfs.btrfs is missing
793 - cryptsetup-generator: allow specification of passwords in crypttab itself
794 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
796 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
797 https://bugs.freedesktop.org/show_bug.cgi?id=54712
799 * create /sbin/init symlinks from the build system
801 * add a dependency on standard-conf.xml and other included files to man pages
803 * MountFlags=shared acts as MountFlags=slave right now.
805 * properly handle loop back mounts via fstab, especially regards to fsck/passno
807 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
812 - add trigger --subsystem-match=usb/usb_device device
813 - reimport udev db after MOVE events for devices without dev_t
815 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
817 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
820 - save coredump in Windows/Mozilla minidump format
821 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
823 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
825 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
827 * be able to specify a forced restart of service A where service B depends on, in case B
828 needs to be auto-respawned?
831 - apply "x" on "D" too (see patch from William Douglas)
833 - instead of ignoring unknown fields, reject them.
834 - creating new directories/subvolumes/fifos/device nodes
835 should not follow symlinks. None of the other adjustment or creation
836 calls follow symlinks.
838 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
840 * verify that the AF_UNIX sockets of a service in the fs still exist
841 when we start a service in order to avoid confusion when a user
842 assumes starting a service is enough to make it accessible
844 * Make it possible to set the keymap independently from the font on
845 the kernel cmdline. Right now setting one resets also the other.
847 * and a dbus call to generate target from current state
849 * write blog stories about:
850 - hwdb: what belongs into it, lsusb
851 - enabling dbus services
853 - how to make changes to sysctl and sysfs attributes
855 - how to pass throw-away units to systemd, or dynamically change properties of existing units
856 - testing with Harald's awesome test kit
858 - how to develop against journal browsing APIs
859 - the journal HTTP iface
860 - non-cgroup resource management
861 - dynamic resource management with cgroups
862 - refreshed, longer missions statement
863 - calendar time events
864 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
865 - how to create your own target
866 - instantiated apache, dovecot and so on
867 - hooking a script into various stages of shutdown/rearly booot
869 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
871 * dot output for --test showing the 'initial transaction'
874 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
875 log both units as UNIT=, so that journalctl -u triggers on both.
876 - generate better errors when people try to set transient properties
877 that are not supported...
878 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
879 - maybe introduce WantsMountsFor=? Usecase:
880 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
881 - recreate systemd's D-Bus private socket file on SIGUSR2
882 - move PAM code into its own binary
883 - when we automatically restart a service, ensure we restart its rdeps, too.
884 - hide PAM options in fragment parser when compile time disabled
885 - Support --test based on current system state
886 - 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().
887 - after deserializing sockets in socket.c we should reapply sockopts and things
888 - drop PID 1 reloading, only do reexecing (difficult: Reload()
889 currently is properly synchronous, Reexec() is weird, because we
890 cannot delay the response properly until we are back, so instead of
891 being properly synchronous we just keep open the fd and close it
892 when done. That means clients do not get a successful method reply,
893 but much rather a disconnect on success.
894 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
895 - when a bus name of a service disappears from the bus make sure to queue further activation requests
898 - allow port=0 in .socket units
899 - maybe introduce ExecRestartPre=
900 - add ReloadSignal= for configuring a reload signal to use
901 - implement Register= switch in .socket units to enable registration
902 in Avahi, RPC and other socket registration services.
903 - allow Type=simple with PIDFile=
904 https://bugzilla.redhat.com/show_bug.cgi?id=723942
905 - allow writing multiple conditions in unit files on one line
906 - load-fragment: when loading a unit file via a chain of symlinks
907 verify that it is not masked via any of the names traversed.
908 - introduce Type=pid-file
909 - introduce mix of BindTo and Requisite
910 - add a concept of RemainAfterExit= to scope units
911 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
914 - Make sure ID_PATH is always exported and complete for
915 network devices where possible, so we can safely rely
917 - check MTUBytes parsing (expecting size_t but we are using unsigned)
920 - add support for more attribute types
921 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
924 - add more keys to [Route] and [Address] sections
925 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
926 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
927 - add reduced [Link] support to .network files
928 - add Scope= parsing option for [Network]
929 - properly handle routerless dhcp leases
930 - work with non-Ethernet devices
931 - add support for more bond options
932 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
933 - the DHCP lease data (such as NTP/DNS) is still made available when
934 a carrier is lost on a link. It should be removed instantly.
935 - expose in the API the following bits:
936 - option 15, domain name and/or option 119, search list
937 - option 12, host name and/or option 81, fqdn
938 - option 123, 144, geolocation
939 - option 252, configure http proxy (PAC/wpad)
940 - provide a way to define a per-network interface default metric value
941 for all routes to it. possibly a second default for DHCP routes.
942 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
943 support Name=foo*|bar*|baz ?
944 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
945 - allow DUID/IAID to be customized, see issue #394.
946 - whenever uplink info changes, make DHCP server send out FORCERENEW
948 * networkd-wait-online:
949 - make operstates to wait for configurable?
952 - figure out how much we can increase Maximum Message Size
955 - add functions to set previously stored IPv6 addresses on startup and get
956 them at shutdown; store them in client->ia_na
957 - write more test cases
958 - implement reconfigure support, see 5.3., 15.11. and 22.20.
959 - implement support for temporary adressess (IA_TA)
960 - implement dhcpv6 authentication
961 - investigate the usefulness of Confirm messages; i.e. are there any
962 situations where the link changes without any loss in carrier detection
964 - some servers don't do rapid commit without a filled in IA_NA, verify
971 - natively watch for dbus-*.service symlinks (PENDING)
972 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
974 * fix alsa mixer restore to not print error when no config is stored
976 * make cryptsetup lower --iter-time
978 * patch kernel for xattr support in /dev, /proc/, /sys?
980 * kernel: add device_type = "fb", "fbcon" to class "graphics"
982 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
984 * /usr/bin/service should actually show the new command line
986 * 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=
988 * fedora: F20: go timer units all the way, leave cron.daily for cron
990 * neither pkexec nor sudo initialize environ[] from the PAM environment?
992 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
994 * register catalog database signature as file magic
996 * zsh shell completion:
997 - <command> <verb> -<TAB> should complete options, but currently does not
998 - systemctl add-wants,add-requires
1003 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1005 * check for strerror(r) instead of strerror(-r)
1007 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
1011 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1013 * use secure_getenv() instead of getenv() where appropriate
1015 * link up selected blog stories from man pages and unit files Documentation= fields
