3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
19 * wiki: update journal format documentation for lz4 additions
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
27 * add some special mode to LogsDirectory=/StateDirectory=… that allows
28 declaring these directories without necessarily pulling in deps for them, or
29 creating them when starting up. That way, we could declare that
30 systemd-journald writes to /var/log/journal, which could be useful when we
31 doing disk usage calculations and so on.
33 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
34 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
35 as the unit is running or has a job queued.
37 * hook up sd-bus' creds stuff with SO_PEERGROUPS
39 * add async version of sd_bus_add_match and make use of that
41 * support projid-based quota in machinectl for containers, and then drop
42 implicit btrfs loopback magic in machined
44 * let's log the "tainted" string at boot
46 * Add NetworkNamespacePath= to specify a path to a network namespace
48 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
49 introduced) as the RTC epoch, instead of the mtime of NEWS.
51 * add a way to lock down cgroup migration: a boolean, which when set for a unit
52 makes sure the processes in it can never migrate out of it
54 * blog about fd store and restartable services
56 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
58 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
59 magic meaning and is no longer upgraded to something else if set explicitly.
61 * add a way to remove fds from the fdstore by name, and make logind use it
63 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
64 make it lose its identity, i.e. be anonymous. For this we'd have to patch
65 through the whole tree to make all code deal with the case where no machine
68 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
69 suitable for processing with rrdtool. Add bus API to access this data, and
70 possibly implement a CPULoad property based on it.
72 * In journalctl add a way how "-o verbose" and suchlike can be tweaked to show
73 only a specific set of properties
75 * beef up pam_systemd to take unit file settings such as cgroups properties as
78 * export UID ranges nspawns's --private-user and DynamicUser= uses in
79 the systemd.pc pkg-config file, the same way we already expose the system
82 * a new "systemd-analyze security" tool outputting a checklist of security
83 features a service does and does not implement
85 * Whenever we check a UID against the system UID range, also check for the
88 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
89 the quota of a the user indicated in User= via unit file settings, like the
90 other resource management concepts. Would mix nicely with DynamicUser=1. Or
91 alternatively, do this with projids, so that we can also cover services
92 running as root. Quota should probably cover all the special dirs such as
93 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
94 is set, plus the whole disk space any image configured with RootImage=.
96 * Introduce "exit" as an EmergencyAction value, and allow to configure a
97 per-unit success/failure exit code to configure. This would be useful for
98 running commands inside of services inside of containers, which could then
99 propagate their failure state all the way up.
101 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
102 disks to see if the UID is already in use.
104 * add dissect_image_warn() as a wrapper around dissect_image() that prints
105 friendly log messages for the returned errors, so that we don't have to
106 duplicate that in nspawn, systemd-dissect and PID 1.
108 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
109 for all units. It should be both a way to pin units into memory as well as a
110 wait to retrieve their exit data.
112 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
113 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
114 automatically. For example, there could be $RUNTIME_DIRECTORY,
115 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
116 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
117 can adapt to varying directories for these purposes. Special care has to be
118 taken if multiple dirs are configured. Maybe avoid setting the env vars in
121 * introduce SuccessAction= that permits shutting down the system when a service
122 succeeds. This is useful to replace "ExecPost=/usr/bin/systemctl poweroff" and
123 similar constructs, which are frequently used. This is particularly nice for
124 implementation of a systemd.run= kernel command line option that runs some
125 command and immediately shuts down.
127 * expose IO accounting data on the bus, show it in systemd-run --wait and log
128 about it in the resource log message
130 * rework unbase64 code to drop whitespace automatically, so that we don't have
133 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
134 unit when it is stopped
136 * show whether a service has out-of-date configuration in "systemctl status" by
137 using mtime data of ConfigurationDirectory=.
139 * replace all uses of fgets() + LINE_MAX by read_line()
141 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
142 creates a static, persistent user rather than a dynamic, transient user. We
143 can leverage code from sysusers.d for this.
145 * add some optional flag to ReadWritePaths= and friends, that has the effect
146 that we create the dir in question when the service is started. Example:
148 ReadWritePaths=:/var/lib/foobar
150 * sort generated hwdb files alphabetically when we import them, so that git
151 diffs remain minimal (in particular: the OUI databases we import are not
152 sorted, and not stable)
154 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
155 the sd-journal logging socket, and, if the timeout is set to 0, sets
156 O_NONBLOCK on it. That way people can control if and when to block for
159 * tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
160 PIDs not managed by the service manager)
162 * hostnamed: populate form factor data from a new hwdb database, so that old
163 yogas can be recognized as "convertible" too, even if they predate the DMI
164 "convertible" form factor
166 * Maybe add a small tool invoked early at boot, that adds in or resizes
167 partitions automatically, to be used when the media used is actually larger
168 than the image written onto it is.
170 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
171 after all. Be strict however, only support the equivalent of nspawn's
172 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
175 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
176 the service cgroup, which is supposed to monitor the service, and when it
177 exits the service is considered failed by its monitor.
179 * track the per-service PAM process properly (i.e. as an additional control
180 process), so that it may be queried on the bus and everything.
182 * add a new "debug" job mode, that is propagated to unit_start() and for
183 services results in two things: we raise SIGSTOP right before invoking
184 execve() and turn off watchdog support. Then, use that to implement
185 "systemd-gdb" for attaching to the start-up of any system service in its
188 * replace all canonicalize_file_name() invocations by chase_symlinks(), in
189 particulr those where a rootdir is relevant.
191 * maybe introduce gpt auto discovery for /var/tmp?
193 * maybe add gpt-partition-based user management: each user gets his own
194 LUKS-encrypted GPT partition with a new GPT type. A small nss module
195 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
196 way: the partition index is added as offset to some fixed base uid. User name
197 is stored in GPT partition name. A PAM module authenticates the user via the
198 LUKS partition password. Benefits: strong per-user security, compatibility
199 with stateless/read-only/verity-enabled root. (other idea: do this based on
200 loopback files in /home, without GPT involvement)
202 * gpt-auto logic: introduce support for discovering /var matching an image. For
203 that, use a partition type UUID that is hashed from the OS name (as encoded
204 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
205 field of the root partition. This way can easily support multiple OS
206 installations on the same GPT partition table, without problems with
207 unmatched /var partitions.
209 * gpt-auto logic: related to the above, maybe support a "secondary" root
210 partition, that is mounted to / and is writable, and where the actual root's
211 /usr is mounted into.
213 * machined: add apis to query /etc/machine-info data of a container
215 * .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly
217 * 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
219 * drop nss-myhostname in favour of nss-resolve?
221 * drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the
222 external nsswitch.conf based one
224 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
225 then use that for the setting used in user@.service. It should be understood
226 relative to the configured default value.
228 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
230 * enable LockMLOCK to take a percentage value relative to physical memory
232 * Permit masking specific netlink APIs with RestrictAddressFamily=
234 * nspawn: start UID allocation loop from hash of container name
236 * nspawn: support that /proc, /sys/, /dev are pre-mounted
238 * define gpt header bits to select volatility mode
240 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
242 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
244 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
246 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
248 * ProtectKeyRing= to take keyring calls away
250 * RemoveKeyRing= to remove all keyring entries of the specified user
252 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
253 on PID 1 with the relevant signals, and makes relevant files in /sys and
254 /proc (such as the sysrq stuff) unavailable
256 * DeviceAllow= should also generate seccomp filters for mknod()
258 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
260 * journalctl: make sure -f ends when the container indicated by -M terminates
262 * mount: automatically search for "main" partition of an image has multiple
265 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
268 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
269 find a way to map the User=/Group= of the service to the right name. This way
270 a user/group for a service only has to exist on the host for the right
273 * allow attaching additional journald log fields to cgroups
275 * add bus API for creating unit files in /etc, reusing the code for transient units
277 * add bus API to remove unit files from /etc
279 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
281 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
282 kernel doesn't support linkat() that replaces existing files, currently)
284 * check if DeviceAllow= should split first, resolve specifiers later
286 * transient units: don't bother with actually setting unit properties, we
287 reload the unit file anyway
289 * journald: sigbus API via a signal-handler safe function that people may call
290 from the SIGBUS handler
292 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
294 * resolved: when routing queries, make sure only look for the *longest* suffix...
296 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
297 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
299 * cache sd_event_now() result from before the first iteration...
301 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
303 * PID1: find a way how we can reload unit file configuration for
304 specific units only, without reloading the whole of systemd
306 * add an explicit parser for LimitRTPRIO= that verifies
307 the specified range and generates sane error messages for incorrect
310 * when we detect that there are waiting jobs but no running jobs, do something
312 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
314 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
316 * there's probably something wrong with having user mounts below /sys,
317 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
318 prefixed with /sys generally special.
319 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
321 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
323 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
325 * mounting and unmounting mount points manually with different source
326 devices will result in collected on all devices used.
327 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
329 * add a job mode that will fail if a transaction would mean stopping
330 running units. Use this in timedated to manage the NTP service
332 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
334 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
335 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
337 * The udev blkid built-in should expose a property that reflects
338 whether media was sensed in USB CF/SD card readers. This should then
339 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
340 picked up by systemd unless they contain a medium. This would mirror
341 the behaviour we already have for CD drives.
343 * networkd/udev: implement SR_IOV configuration in .link files:
344 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
346 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
348 * Port various tools to make use of verbs.[ch], where applicable: busctl,
349 coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
351 * hostnamectl: show root image uuid
353 * sysfs set api in libudev is not const
355 * Find a solution for SMACK capabilities stuff:
356 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
358 * "systemctl preset-all" should probably order the unit files it
359 operates on lexicographically before starting to work, in order to
360 ensure deterministic behaviour if two unit files conflict (like DMs
363 * synchronize console access with BSD locks:
364 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
366 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
367 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
369 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
371 * figure out when we can use the coarse timers
373 * add "systemctl start -v foobar.service" that shows logs of a service
374 while the start command runs. This is non-trivial to do without
375 races though, since we should flush out all journal messages before
376 returning from the "systemctl stop".
378 * 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
380 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
382 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
384 * consider showing the unit names during boot up in the status output, not just the unit descriptions
386 * maybe allow timer units with an empty Units= setting, so that they
387 can be used for resuming the system but nothing else.
389 * what to do about udev db binary stability for apps? (raw access is not an option)
391 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
393 * man: maybe use the word "inspect" rather than "introspect"?
395 * systemctl: if some operation fails, show log output?
397 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
398 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
400 * exponential backoff in timesyncd when we cannot reach a server
402 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
404 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
406 * systemd.show_status= should probably have a mode where only failed
409 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
410 (throughout the codebase, not only PID1)
414 - service registration
415 - service/domain/types browsing
417 - DNS-SD service registration from socket units
418 - resolved should optionally register additional per-interface LLMNR
419 names, so that for the container case we can establish the same name
420 (maybe "host") for referencing the server, everywhere.
421 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
422 - hook up resolved with machined-based address resolution
424 * refcounting in sd-resolve is borked
426 * Add a new verb "systemctl top"
428 * add new gpt type for btrfs volumes
430 * support empty /etc boots nicely:
431 - nspawn/gpt-generator: introduce new gpt partition type for /usr
433 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
435 * a way for container managers to turn off getty starting via $container_headless= or so...
437 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
439 * mount_cgroup_controllers(): symlinks need to get the label applied
441 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
442 they run added to the initial transaction and thus confuse Type=idle.
444 * add bus api to query unit file's X fields.
446 * gpt-auto-generator:
447 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
448 - Make /home automount rather than mount?
450 * add generator that pulls in systemd-network from containers when
451 CAP_NET_ADMIN is set, more than the loopback device is defined, even
452 when it is otherwise off
454 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
456 * implement Distribute= in socket units to allow running multiple
457 service instances processing the listening socket, and open this up
460 * socket units: support creating sockets in different namespace,
461 opening it up for JoinsNamespaceOf=. This would require to fork off
462 a tiny process that joins the namespace and creates/binds the socket
463 and passes this back to PID1 via SCM_RIGHTS. This also could be used
464 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
466 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
467 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
468 should SIGSTOP all unit processes in a loop until all processes of
469 it are fully stopped. This can later be used for app management by
470 desktop UIs such as gnome-shell to freeze apps that are not visible
471 on screen, not unlike how job control works on the shell
474 - implement per-slice CPUFairScheduling=1 switch
475 - handle jointly mounted controllers correctly
476 - introduce high-level settings for RT budget, swappiness
477 - how to reset dynamically changed unit cgroup attributes sanely?
478 - when reloading configuration, apply new cgroup configuration
479 - when recursively showing the cgroup hierarchy, optionally also show
480 the hierarchies of child processes
483 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
484 - ensure scope units may be started only a single time
486 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
488 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
490 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
492 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
494 * 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
496 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
498 * If we try to find a unit via a dangling symlink, generate a clean
499 error. Currently, we just ignore it and read the unit from the search
502 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
504 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
506 * load .d/*.conf dropins for device units
508 * allow implementation of InaccessibleDirectories=/ plus
509 ReadOnlyDirectories=... for whitelisting files for a service.
513 - GetAllProperties() on a non-existing object does not result in a failure currently
514 - port to sd-resolve for connecting to TCP dbus servers
515 - 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
516 - see if we can drop more message validation on the sending side
517 - add API to clone sd_bus_message objects
518 - make AddMatch calls on dbus1 transports async?
519 - longer term: priority inheritance
521 - NameLost/NameAcquired obsolete
524 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
525 - test bloom filter generation indexes
528 - allow multiple signal handlers per signal?
529 - document chaining of signal handler for SIGCHLD and child handlers
530 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
531 - generate a failure of a default event loop is executed out-of-thread
532 - maybe add support for inotify events
534 * investigate endianness issues of UUID vs. GUID
536 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
537 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
539 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
541 * add a pam module that on password changes updates any LUKS slot where the password matches
543 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
546 - add 'set -e' to scripts in test/
547 - make stuff in test/ work with separate output dir
549 * seems that when we follow symlinks to units we prefer the symlink
550 destination path over /etc and /usr. We should not do that. Instead
551 /etc should always override /run+/usr and also any symlink
554 * when isolating, try to figure out a way how we implicitly can order
555 all units we stop before the isolating unit...
557 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
559 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
560 that the boot loader should be installed to the ESP. Define a way
561 how an installer can figure out whether a BLS compliant boot loader
564 * think about requeuing jobs when daemon-reload is issued? usecase:
565 the initrd issues a reload after fstab from the host is accessible
566 and we might want to requeue the mounts local-fs acquired through
569 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
571 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
573 * shutdown logging: store to EFI var, and store to USB stick?
575 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
577 * merge unit_kill_common() and unit_kill_context()
579 * introduce ExecCondition= in services
582 - honor language efi variables for default language selection (if there are any?)
583 - honor timezone efi variables for default timezone selection (if there are any?)
584 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
586 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
588 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
590 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
593 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
594 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
595 - logind: wakelock/opportunistic suspend support
596 - Add pretty name for seats in logind
597 - logind: allow showing logout dialog from system?
598 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
599 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
600 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
601 - if pam_systemd is invoked by su from a process that is outside of a
602 any session we should probably just become a NOP, since that's
603 usually not a real user session but just some system code that just
605 - logind: make the Suspend()/Hibernate() bus calls wait for the for
606 the job to be completed. before returning, so that clients can wait
607 for "systemctl suspend" to finish to know when the suspending is
609 - logind: when the power button is pressed short, just popup a
610 logout dialog. If it is pressed for 1s, do the usual
611 shutdown. Inspiration are Macs here.
612 - expose "Locked" property on logind sesison objects
613 - given that logind now lets PID 1 do all nasty work, we can
614 probably reduce the capability set it retains substantially.
615 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
616 - expose orientation sensors and tablet mode through logind
617 - maybe allow configuration of the StopTimeout for session scopes
618 - rename session scope so that it includes the UID. THat way
619 the session scope can be arranged freely in slices and we don't have
620 make assumptions about their slice anymore.
621 - follow PropertiesChanged state more closely, to deal with quick logouts and
624 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
626 * service: watchdog logic: for testing purposes allow ping, but do not require pong
629 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
630 - import and delete pstore filesystem content at startup
631 - journald: also get thread ID from client, plus thread name
632 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
633 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
634 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
635 - declare the local journal protocol stable in the wiki interface chart
636 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
637 - journald: when dropping msgs due to ratelimit make sure to write
638 "dropped %u messages" not only when we are about to print the next
639 message that works, but alraedy after a short tiemout
640 - check if we can make journalctl by default use --follow mode inside of less if called without args?
641 - maybe add API to send pairs of iovecs via sd_journal_send
642 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
643 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
644 and !FOOBAR for events without FOOBAR.
645 - journal: store timestamp of journal_file_set_offline() int he header,
646 so it is possible to display when the file was last synced.
647 - 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.
648 - journal: find a way to allow dropping history early, based on priority, other rules
649 - journal: When used on NFS, check payload hashes
650 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
651 - refuse taking lower-case variable names in sd_journal_send() and friends.
652 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
653 - journal: deal nicely with byte-by-byte copied files, especially regards header
654 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
655 - Replace utmp, wtmp, btmp, and lastlog completely with journal
656 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
657 - when a kernel driver logs in a tight loop, we should ratelimit that too.
658 - journald: optionally, log debug messages to /run but everything else to /var
659 - journald: when we drop syslog messages because the syslog socket is
660 full, make sure to write how many messages are lost as first thing
661 to syslog when it works again.
662 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
663 - change systemd-journal-flush into a service that stays around during
664 boot, and causes the journal to be moved back to /run on shutdown,
665 so that we do not keep /var busy. This needs to happen synchronously,
666 hence doing this via signals is not going to work.
667 - optionally support running journald from the command line for testing purposes in external projects
668 - journald: allow per-priority and per-service retention times when rotating/vacuuming
669 - journald: make use of uid-range.h to managed uid ranges to split
671 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
672 - improve journalctl performance by loading journal files
673 lazily. Encode just enough information in the file name, so that we
674 do not have to open it to know that it is not interesting for us, for
675 the most common operations.
676 - journal-or-kmsg is currently broken? See reverted
677 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
678 - man: document that corrupted journal files is nothing to act on
679 - rework journald sigbus stuff to use mutex
680 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
681 services that run under their own user ids, and use User= (but only
682 in a world where userns is ubiquitous since otherwise we cannot
683 invoke those daemons on the host AND in a container anymore). Also,
684 if LimitNPROC= is used without User= we should warn and refuse
686 - journalctl --verify: don't show files that are currently being
687 written to as FAIL, but instead show that their are being written to.
688 - add journalctl -H that talks via ssh to a remote peer and passes through
690 - add a version of --merge which also merges /var/log/journal/remote
691 - log accumulated resource usage after each service invocation
692 - journalctl: -m should access container journals directly by enumerating
693 them via machined, and also watch containers coming and going.
694 Benefit: nspawn --ephemeral would start working nicely with the journal.
695 - assign MESSAGE_ID to log messages about failed services
698 - document that deps in [Unit] sections ignore Alias= fields in
699 [Install] units of other units, unless those units are disabled
700 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
701 - document that service reload may be implemented as service reexec
702 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
703 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
704 - document systemd-journal-flush.service properly
705 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
706 - man: document the very specific env the shutdown drop-in tools live in
707 - man: add more examples to man pages
708 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
711 - add systemctl switch to dump transaction without executing it
712 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
713 - "systemctl disable" on a static unit prints no message and does
714 nothing. "systemctl enable" does nothing, and gives a bad message
715 about it. Should fix both to print nice actionable messages.
716 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
717 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
718 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
719 - systemctl: "Journal has been rotated since unit was started." message is misleading
720 - better error message if you run systemctl without systemd running
721 - systemctl status output should include list of triggering units and their status
724 - "systemctl mask" should find all names by which a unit is accessible
725 (i.e. by scanning for symlinks to it) and link them all to /dev/null
728 - timer units should get the ability to trigger when:
729 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
731 - Modulate timer frequency based on battery state
733 * add libsystemd-password or so to query passwords during boot using the password agent logic
735 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
737 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
739 * make repeated alt-ctrl-del presses printing a dump
741 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
743 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
746 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
747 with seccomp. That should provide us with a useful log buffer that
748 systemd can log to during early boot, and disconnect container logs
749 from the kernel's logs.
750 - as soon as networkd has a bus interface, hook up --network-interface=,
751 --network-bridge= with networkd, to trigger netdev creation should an
753 - a nice way to boot up without machine id set, so that it is set at boot
754 automatically for supporting --ephemeral. Maybe hash the host machine id
755 together with the machine name to generate the machine id for the container
756 - fix logic always print a final newline on output.
757 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
758 - should optionally support receiving WATCHDOG=1 messages from its payload
760 - should send out sd_notify("WATCHDOG=1") messages
761 - optionally automatically add FORWARD rules to iptables whenever nspawn is
762 running, remove them when shut down.
763 - Improve error message when --bind= is used on a non-existing source
765 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
769 - refuse mounting over a mount point
770 - automatically discover .roothash files in dissect, similarly to nspawn
773 - add an API so that libvirt-lxc can inform us about network interfaces being
774 removed or added to an existing machine
775 - "machinectl migrate" or similar to copy a container from or to a
776 difference host, via ssh
777 - introduce systemd-nspawn-ephemeral@.service, and hook it into
778 "machinectl start" with a new --ephemeral switch
779 - "machinectl status" should also show internal logs of the container in
781 - "machinectl list-images" should show os-release data, as well as
782 machine-info data (including deployment level)
783 - "machinectl history"
785 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
786 shell in it, and marks it read-only after use
789 - generate a nice warning if mkfs.btrfs is missing
792 - cryptsetup-generator: allow specification of passwords in crypttab itself
793 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
795 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
796 https://bugs.freedesktop.org/show_bug.cgi?id=54712
798 * create /sbin/init symlinks from the build system
800 * add a dependency on standard-conf.xml and other included files to man pages
802 * MountFlags=shared acts as MountFlags=slave right now.
804 * properly handle loop back mounts via fstab, especially regards to fsck/passno
806 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
811 - add trigger --subsystem-match=usb/usb_device device
812 - reimport udev db after MOVE events for devices without dev_t
814 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
816 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
819 - save coredump in Windows/Mozilla minidump format
820 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
822 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
824 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
826 * be able to specify a forced restart of service A where service B depends on, in case B
827 needs to be auto-respawned?
830 - apply "x" on "D" too (see patch from William Douglas)
832 - instead of ignoring unknown fields, reject them.
833 - creating new directories/subvolumes/fifos/device nodes
834 should not follow symlinks. None of the other adjustment or creation
835 calls follow symlinks.
837 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
839 * verify that the AF_UNIX sockets of a service in the fs still exist
840 when we start a service in order to avoid confusion when a user
841 assumes starting a service is enough to make it accessible
843 * Make it possible to set the keymap independently from the font on
844 the kernel cmdline. Right now setting one resets also the other.
846 * and a dbus call to generate target from current state
848 * write blog stories about:
849 - hwdb: what belongs into it, lsusb
850 - enabling dbus services
852 - how to make changes to sysctl and sysfs attributes
854 - how to pass throw-away units to systemd, or dynamically change properties of existing units
855 - testing with Harald's awesome test kit
857 - how to develop against journal browsing APIs
858 - the journal HTTP iface
859 - non-cgroup resource management
860 - dynamic resource management with cgroups
861 - refreshed, longer missions statement
862 - calendar time events
863 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
864 - how to create your own target
865 - instantiated apache, dovecot and so on
866 - hooking a script into various stages of shutdown/rearly booot
868 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
870 * dot output for --test showing the 'initial transaction'
873 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
874 log both units as UNIT=, so that journalctl -u triggers on both.
875 - generate better errors when people try to set transient properties
876 that are not supported...
877 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
878 - maybe introduce WantsMountsFor=? Usecase:
879 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
880 - recreate systemd's D-Bus private socket file on SIGUSR2
881 - move PAM code into its own binary
882 - when we automatically restart a service, ensure we restart its rdeps, too.
883 - hide PAM options in fragment parser when compile time disabled
884 - Support --test based on current system state
885 - 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().
886 - after deserializing sockets in socket.c we should reapply sockopts and things
887 - drop PID 1 reloading, only do reexecing (difficult: Reload()
888 currently is properly synchronous, Reexec() is weird, because we
889 cannot delay the response properly until we are back, so instead of
890 being properly synchronous we just keep open the fd and close it
891 when done. That means clients do not get a successful method reply,
892 but much rather a disconnect on success.
893 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
894 - when a bus name of a service disappears from the bus make sure to queue further activation requests
897 - allow port=0 in .socket units
898 - maybe introduce ExecRestartPre=
899 - add ReloadSignal= for configuring a reload signal to use
900 - implement Register= switch in .socket units to enable registration
901 in Avahi, RPC and other socket registration services.
902 - allow Type=simple with PIDFile=
903 https://bugzilla.redhat.com/show_bug.cgi?id=723942
904 - allow writing multiple conditions in unit files on one line
905 - load-fragment: when loading a unit file via a chain of symlinks
906 verify that it is not masked via any of the names traversed.
907 - introduce Type=pid-file
908 - introduce mix of BindTo and Requisite
909 - add a concept of RemainAfterExit= to scope units
910 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
913 - Make sure ID_PATH is always exported and complete for
914 network devices where possible, so we can safely rely
916 - check MTUBytes parsing (expecting size_t but we are using unsigned)
919 - add support for more attribute types
920 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
923 - add more keys to [Route] and [Address] sections
924 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
925 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
926 - add reduced [Link] support to .network files
927 - add Scope= parsing option for [Network]
928 - properly handle routerless dhcp leases
929 - work with non-Ethernet devices
930 - add support for more bond options
931 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
932 - the DHCP lease data (such as NTP/DNS) is still made available when
933 a carrier is lost on a link. It should be removed instantly.
934 - expose in the API the following bits:
935 - option 15, domain name and/or option 119, search list
936 - option 12, host name and/or option 81, fqdn
937 - option 123, 144, geolocation
938 - option 252, configure http proxy (PAC/wpad)
939 - provide a way to define a per-network interface default metric value
940 for all routes to it. possibly a second default for DHCP routes.
941 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
942 support Name=foo*|bar*|baz ?
943 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
944 - allow DUID/IAID to be customized, see issue #394.
945 - whenever uplink info changes, make DHCP server send out FORCERENEW
947 * networkd-wait-online:
948 - make operstates to wait for configurable?
951 - figure out how much we can increase Maximum Message Size
954 - add functions to set previously stored IPv6 addresses on startup and get
955 them at shutdown; store them in client->ia_na
956 - write more test cases
957 - implement reconfigure support, see 5.3., 15.11. and 22.20.
958 - implement support for temporary adressess (IA_TA)
959 - implement dhcpv6 authentication
960 - investigate the usefulness of Confirm messages; i.e. are there any
961 situations where the link changes without any loss in carrier detection
963 - some servers don't do rapid commit without a filled in IA_NA, verify
970 - natively watch for dbus-*.service symlinks (PENDING)
971 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
973 * fix alsa mixer restore to not print error when no config is stored
975 * make cryptsetup lower --iter-time
977 * patch kernel for xattr support in /dev, /proc/, /sys?
979 * kernel: add device_type = "fb", "fbcon" to class "graphics"
981 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
983 * /usr/bin/service should actually show the new command line
985 * 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=
987 * fedora: F20: go timer units all the way, leave cron.daily for cron
989 * neither pkexec nor sudo initialize environ[] from the PAM environment?
991 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
993 * register catalog database signature as file magic
995 * zsh shell completion:
996 - <command> <verb> -<TAB> should complete options, but currently does not
997 - systemctl add-wants,add-requires
1002 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1004 * check for strerror(r) instead of strerror(-r)
1006 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
1010 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1012 * use secure_getenv() instead of getenv() where appropriate
1014 * link up selected blog stories from man pages and unit files Documentation= fields
