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 a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
28 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
29 as the unit is running or has a job queued.
31 * let's log the "tainted" string at boot
33 * Add NetworkNamespacePath= to specify a path to a network namespace
35 * Add StandardInputData= and StandardInputText= for putting together data to
36 pass to a service through stdin
38 * Add StandardInputPath=, StandardOutputPath=, StandardErrorPath= to connect a
39 service to a specific file. Be smart, and if the specified path refers to an
40 AF_UNIX socket, connect() to it.
42 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
43 introduced) as the RTC epoch, instead of the mtime of NEWS.
45 * add a way to lock down cgroup migration: a boolean, which when set for a unit
46 makes sure the processes in it can never migrate out of it
48 * complain if a unit starts up and there are already processes in its cgroup
50 * blog about fd store and restartable services
52 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
54 * add a way to remove fds from the fdstore by name, and make logind use it
56 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
57 make it lose its identity, i.e. be anonymous. For this we'd have to patch
58 through the whole tree to make all code deal with the case where no machine
61 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
62 suitable for processing with rrdtool. Add bus API to access this data, and
63 possibly implement a CPULoad property based on it.
65 * In journalctl add a way how "-o verbose" and suchlike can be tweaked to show
66 only a specific set of properties
68 * beef up pam_systemd to take unit file settings such as cgroups properties as
71 * export UID ranges nspawns's --private-user and DynamicUser= uses in
72 the systemd.pc pkg-config file, the same way we already expose the system
75 * a new "systemd-analyze security" tool outputting a checklist of security
76 features a service does and does not implement
78 * Whenever we check a UID against the system UID range, also check for the
81 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
82 the quota of a the user indicated in User= via unit file settings, like the
83 other resource management concepts. Would mix nicely with DynamicUser=1
85 * add dissect_image_warn() as a wrapper around dissect_image() that prints
86 friendly log messages for the returned errors, so that we don't have to
87 duplicate that in nspawn, systemd-dissect and PID 1.
89 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
90 for all units. It should be both a way to pin units into memory as well as a
91 wait to retrieve their exit data.
93 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
94 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
95 automatically. For example, there could be $RUNTIME_DIRECTORY,
96 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
97 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
98 can adapt to varying directories for these purposes. Special care has to be
99 taken if multiple dirs are configured. Maybe avoid setting the env vars in
102 * expose IO accounting data on the bus, show it in systemd-run --wait and log
103 about it in the resource log message
105 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
106 unit when it is stopped
108 * show whether a service has out-of-date configuration in "systemctl status" by
109 using mtime data of ConfigurationDirectory=.
111 * replace all uses of fgets() + LINE_MAX by read_line()
113 * set IPAddressDeny=any on all services that shouldn't do networking (possibly
114 combined with IPAddressAllow=localhost).
116 * dissect: when we discover squashfs, don't claim we had a "writable" partition
119 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
120 creates a static, persistent user rather than a dynamic, transient user. We
121 can leverage code from sysusers.d for this.
123 * add some optional flag to ReadWritePaths= and friends, that has the effect
124 that we create the dir in question when the service is started. Example:
126 ReadWritePaths=:/var/lib/foobar
128 * sort generated hwdb files alphabetically when we import them, so that git
129 diffs remain minimal (in particular: the OUI databases we import are not
130 sorted, and not stable)
132 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
133 the sd-journal logging socket, and, if the timeout is set to 0, sets
134 O_NONBLOCK on it. That way people can control if and when to block for
137 * tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
138 PIDs not managed by the service manager)
140 * hostnamed: populate form factor data from a new hwdb database, so that old
141 yogas can be recognized as "convertible" too, even if they predate the DMI
142 "convertible" form factor
144 * Maybe add a small tool invoked early at boot, that adds in or resizes
145 partitions automatically, to be used when the media used is actually larger
146 than the image written onto it is.
148 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
149 after all. Be strict however, only support the equivalent of nspawn's
150 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
153 * change the dependency Set* objects in Unit structures to become Hashmap*, and
154 then store a bit mask who created a specific dependency: the source unit via
155 fragment configuration, the destination unit via fragment configuration, or
156 the source unit via udev rules (in case of .device units), or any combination
157 thereof. This information can then be used to flush out old udev-created
158 dependencies when the udev properties change, and eventually to implement a
159 "systemctl refresh" operation for reloading the configuration of individual
160 units without reloading the whole set.
162 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
163 the service cgroup, which is supposed to monitor the service, and when it
164 exits the service is considered failed by its monitor.
166 * track the per-service PAM process properly (i.e. as an additional control
167 process), so that it may be queried on the bus and everything.
169 * add a new "debug" job mode, that is propagated to unit_start() and for
170 services results in two things: we raise SIGSTOP right before invoking
171 execve() and turn off watchdog support. Then, use that to implement
172 "systemd-gdb" for attaching to the start-up of any system service in its
175 * replace all canonicalize_file_name() invocations by chase_symlinks(), in
176 particulr those where a rootdir is relevant.
178 * maybe introduce gpt auto discovery for /var/tmp?
180 * maybe add gpt-partition-based user management: each user gets his own
181 LUKS-encrypted GPT partition with a new GPT type. A small nss module
182 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
183 way: the partition index is added as offset to some fixed base uid. User name
184 is stored in GPT partition name. A PAM module authenticates the user via the
185 LUKS partition password. Benefits: strong per-user security, compatibility
186 with stateless/read-only/verity-enabled root. (other idea: do this based on
187 loopback files in /home, without GPT involvement)
189 * gpt-auto logic: introduce support for discovering /var matching an image. For
190 that, use a partition type UUID that is hashed from the OS name (as encoded
191 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
192 field of the root partition. This way can easily support multiple OS
193 installations on the same GPT partition table, without problems with
194 unmatched /var partitions.
196 * gpt-auto logic: related to the above, maybe support a "secondary" root
197 partition, that is mounted to / and is writable, and where the actual root's
198 /usr is mounted into.
200 * machined: add apis to query /etc/machine-info data of a container
202 * .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly
204 * 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
206 * drop nss-myhostname in favour of nss-resolve?
208 * drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the
209 external nsswitch.conf based one
211 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
212 then use that for the setting used in user@.service. It should be understood
213 relative to the configured default value.
215 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
217 * enable LockMLOCK to take a percentage value relative to physical memory
219 * Permit masking specific netlink APIs with RestrictAddressFamily=
221 * nspawn: start UID allocation loop from hash of container name
223 * nspawn: support that /proc, /sys/, /dev are pre-mounted
225 * define gpt header bits to select volatility mode
227 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
229 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
231 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
233 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
235 * ProtectKeyRing= to take keyring calls away
237 * RemoveKeyRing= to remove all keyring entries of the specified user
239 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
240 on PID 1 with the relevant signals, and makes relevant files in /sys and
241 /proc (such as the sysrq stuff) unavailable
243 * DeviceAllow= should also generate seccomp filters for mknod()
245 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
247 * journalctl: make sure -f ends when the container indicated by -M terminates
249 * mount: automatically search for "main" partition of an image has multiple
252 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
255 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
256 find a way to map the User=/Group= of the service to the right name. This way
257 a user/group for a service only has to exist on the host for the right
260 * allow attaching additional journald log fields to cgroups
262 * add bus API for creating unit files in /etc, reusing the code for transient units
264 * add bus API to remove unit files from /etc
266 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
268 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
269 kernel doesn't support linkat() that replaces existing files, currently)
271 * check if DeviceAllow= should split first, resolve specifiers later
273 * transient units: don't bother with actually setting unit properties, we
274 reload the unit file anyway
276 * journald: sigbus API via a signal-handler safe function that people may call
277 from the SIGBUS handler
279 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
281 * resolved: when routing queries, make sure only look for the *longest* suffix...
283 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
284 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
286 * cache sd_event_now() result from before the first iteration...
288 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
290 * PID1: find a way how we can reload unit file configuration for
291 specific units only, without reloading the whole of systemd
293 * add an explicit parser for LimitRTPRIO= that verifies
294 the specified range and generates sane error messages for incorrect
297 * do something about "/control" subcgroups in the unified cgroup hierarchy
299 * when we detect that there are waiting jobs but no running jobs, do something
301 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
303 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
305 * there's probably something wrong with having user mounts below /sys,
306 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
307 prefixed with /sys generally special.
308 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
310 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
312 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
314 * mounting and unmounting mount points manually with different source
315 devices will result in collected on all devices used.
316 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
318 * add a job mode that will fail if a transaction would mean stopping
319 running units. Use this in timedated to manage the NTP service
321 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
323 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
324 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
326 * The udev blkid built-in should expose a property that reflects
327 whether media was sensed in USB CF/SD card readers. This should then
328 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
329 picked up by systemd unless they contain a medium. This would mirror
330 the behaviour we already have for CD drives.
332 * networkd/udev: implement SR_IOV configuration in .link files:
333 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
335 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
337 * implement a per-service firewall based on net_cls
339 * Port various tools to make use of verbs.[ch], where applicable: busctl,
340 coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
342 * hostnamectl: show root image uuid
344 * sysfs set api in libudev is not const
346 * Find a solution for SMACK capabilities stuff:
347 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
349 * "systemctl preset-all" should probably order the unit files it
350 operates on lexicographically before starting to work, in order to
351 ensure deterministic behaviour if two unit files conflict (like DMs
354 * synchronize console access with BSD locks:
355 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
357 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
358 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
360 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
362 * figure out when we can use the coarse timers
364 * add "systemctl start -v foobar.service" that shows logs of a service
365 while the start command runs. This is non-trivial to do without
366 races though, since we should flush out all journal messages before
367 returning from the "systemctl stop".
369 * 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
371 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
373 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
375 * consider showing the unit names during boot up in the status output, not just the unit descriptions
377 * maybe allow timer units with an empty Units= setting, so that they
378 can be used for resuming the system but nothing else.
380 * what to do about udev db binary stability for apps? (raw access is not an option)
382 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
384 * man: maybe use the word "inspect" rather than "introspect"?
386 * systemctl: if some operation fails, show log output?
388 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
389 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
391 * exponential backoff in timesyncd when we cannot reach a server
393 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
395 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
397 * systemd.show_status= should probably have a mode where only failed
400 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
401 (throughout the codebase, not only PID1)
405 - service registration
406 - service/domain/types browsing
408 - DNS-SD service registration from socket units
409 - resolved should optionally register additional per-interface LLMNR
410 names, so that for the container case we can establish the same name
411 (maybe "host") for referencing the server, everywhere.
412 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
413 - hook up resolved with machined-based address resolution
415 * refcounting in sd-resolve is borked
417 * Add a new verb "systemctl top"
419 * add new gpt type for btrfs volumes
421 * support empty /etc boots nicely:
422 - nspawn/gpt-generator: introduce new gpt partition type for /usr
424 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
426 * a way for container managers to turn off getty starting via $container_headless= or so...
428 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
430 * mount_cgroup_controllers(): symlinks need to get the label applied
432 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
433 they run added to the initial transaction and thus confuse Type=idle.
435 * add bus api to query unit file's X fields.
437 * gpt-auto-generator:
438 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
439 - Make /home automount rather than mount?
441 * add generator that pulls in systemd-network from containers when
442 CAP_NET_ADMIN is set, more than the loopback device is defined, even
443 when it is otherwise off
445 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
447 * implement Distribute= in socket units to allow running multiple
448 service instances processing the listening socket, and open this up
451 * socket units: support creating sockets in different namespace,
452 opening it up for JoinsNamespaceOf=. This would require to fork off
453 a tiny process that joins the namespace and creates/binds the socket
454 and passes this back to PID1 via SCM_RIGHTS. This also could be used
455 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
457 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
458 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
459 should SIGSTOP all unit processes in a loop until all processes of
460 it are fully stopped. This can later be used for app management by
461 desktop UIs such as gnome-shell to freeze apps that are not visible
462 on screen, not unlike how job control works on the shell
465 - implement per-slice CPUFairScheduling=1 switch
466 - handle jointly mounted controllers correctly
467 - introduce high-level settings for RT budget, swappiness
468 - how to reset dynamically changed unit cgroup attributes sanely?
469 - when reloading configuration, apply new cgroup configuration
470 - when recursively showing the cgroup hierarchy, optionally also show
471 the hierarchies of child processes
474 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
475 - ensure scope units may be started only a single time
477 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
479 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
481 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
483 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
485 * 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
487 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
489 * If we try to find a unit via a dangling symlink, generate a clean
490 error. Currently, we just ignore it and read the unit from the search
493 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
495 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
497 * load .d/*.conf dropins for device units
499 * allow implementation of InaccessibleDirectories=/ plus
500 ReadOnlyDirectories=... for whitelisting files for a service.
504 - GetAllProperties() on a non-existing object does not result in a failure currently
505 - port to sd-resolve for connecting to TCP dbus servers
506 - 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
507 - see if we can drop more message validation on the sending side
508 - add API to clone sd_bus_message objects
509 - make AddMatch calls on dbus1 transports async?
510 - longer term: priority inheritance
512 - NameLost/NameAcquired obsolete
515 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
516 - test bloom filter generation indexes
519 - allow multiple signal handlers per signal?
520 - document chaining of signal handler for SIGCHLD and child handlers
521 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
522 - generate a failure of a default event loop is executed out-of-thread
523 - maybe add support for inotify events
525 * investigate endianness issues of UUID vs. GUID
527 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
528 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
530 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
532 * add a pam module that on password changes updates any LUKS slot where the password matches
534 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
537 - add 'set -e' to scripts in test/
538 - make stuff in test/ work with separate output dir
540 * seems that when we follow symlinks to units we prefer the symlink
541 destination path over /etc and /usr. We should not do that. Instead
542 /etc should always override /run+/usr and also any symlink
545 * when isolating, try to figure out a way how we implicitly can order
546 all units we stop before the isolating unit...
548 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
550 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
551 that the boot loader should be installed to the ESP. Define a way
552 how an installer can figure out whether a BLS compliant boot loader
555 * think about requeuing jobs when daemon-reload is issued? usecase:
556 the initrd issues a reload after fstab from the host is accessible
557 and we might want to requeue the mounts local-fs acquired through
560 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
562 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
564 * shutdown logging: store to EFI var, and store to USB stick?
566 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
568 * merge unit_kill_common() and unit_kill_context()
570 * introduce ExecCondition= in services
573 - honor language efi variables for default language selection (if there are any?)
574 - honor timezone efi variables for default timezone selection (if there are any?)
575 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
577 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
579 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
581 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
584 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
585 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
586 - logind: wakelock/opportunistic suspend support
587 - Add pretty name for seats in logind
588 - logind: allow showing logout dialog from system?
589 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
590 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
591 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
592 - if pam_systemd is invoked by su from a process that is outside of a
593 any session we should probably just become a NOP, since that's
594 usually not a real user session but just some system code that just
596 - logind: make the Suspend()/Hibernate() bus calls wait for the for
597 the job to be completed. before returning, so that clients can wait
598 for "systemctl suspend" to finish to know when the suspending is
600 - logind: when the power button is pressed short, just popup a
601 logout dialog. If it is pressed for 1s, do the usual
602 shutdown. Inspiration are Macs here.
603 - expose "Locked" property on logind sesison objects
604 - given that logind now lets PID 1 do all nasty work, we can
605 probably reduce the capability set it retains substantially.
606 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
607 - expose orientation sensors and tablet mode through logind
608 - maybe allow configuration of the StopTimeout for session scopes
609 - rename session scope so that it includes the UID. THat way
610 the session scope can be arranged freely in slices and we don't have
611 make assumptions about their slice anymore.
612 - follow PropertiesChanged state more closely, to deal with quick logouts and
615 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
617 * service: watchdog logic: for testing purposes allow ping, but do not require pong
620 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
621 - import and delete pstore filesystem content at startup
622 - journald: also get thread ID from client, plus thread name
623 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
624 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
625 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
626 - declare the local journal protocol stable in the wiki interface chart
627 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
628 - journald: when dropping msgs due to ratelimit make sure to write
629 "dropped %u messages" not only when we are about to print the next
630 message that works, but alraedy after a short tiemout
631 - check if we can make journalctl by default use --follow mode inside of less if called without args?
632 - maybe add API to send pairs of iovecs via sd_journal_send
633 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
634 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
635 and !FOOBAR for events without FOOBAR.
636 - journal: store timestamp of journal_file_set_offline() int he header,
637 so it is possible to display when the file was last synced.
638 - 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.
639 - journal: find a way to allow dropping history early, based on priority, other rules
640 - journal: When used on NFS, check payload hashes
641 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
642 - refuse taking lower-case variable names in sd_journal_send() and friends.
643 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
644 - journal: deal nicely with byte-by-byte copied files, especially regards header
645 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
646 - Replace utmp, wtmp, btmp, and lastlog completely with journal
647 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
648 - when a kernel driver logs in a tight loop, we should ratelimit that too.
649 - journald: optionally, log debug messages to /run but everything else to /var
650 - journald: when we drop syslog messages because the syslog socket is
651 full, make sure to write how many messages are lost as first thing
652 to syslog when it works again.
653 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
654 - change systemd-journal-flush into a service that stays around during
655 boot, and causes the journal to be moved back to /run on shutdown,
656 so that we do not keep /var busy. This needs to happen synchronously,
657 hence doing this via signals is not going to work.
658 - optionally support running journald from the command line for testing purposes in external projects
659 - journald: allow per-priority and per-service retention times when rotating/vacuuming
660 - journald: make use of uid-range.h to managed uid ranges to split
662 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
663 - improve journalctl performance by loading journal files
664 lazily. Encode just enough information in the file name, so that we
665 do not have to open it to know that it is not interesting for us, for
666 the most common operations.
667 - journal-or-kmsg is currently broken? See reverted
668 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
669 - man: document that corrupted journal files is nothing to act on
670 - rework journald sigbus stuff to use mutex
671 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
672 services that run under their own user ids, and use User= (but only
673 in a world where userns is ubiquitous since otherwise we cannot
674 invoke those daemons on the host AND in a container anymore). Also,
675 if LimitNPROC= is used without User= we should warn and refuse
677 - journalctl --verify: don't show files that are currently being
678 written to as FAIL, but instead show that their are being written to.
679 - add journalctl -H that talks via ssh to a remote peer and passes through
681 - add a version of --merge which also merges /var/log/journal/remote
682 - log accumulated resource usage after each service invocation
683 - journalctl: -m should access container journals directly by enumerating
684 them via machined, and also watch containers coming and going.
685 Benefit: nspawn --ephemeral would start working nicely with the journal.
686 - assign MESSAGE_ID to log messages about failed services
689 - document that deps in [Unit] sections ignore Alias= fields in
690 [Install] units of other units, unless those units are disabled
691 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
692 - document the exit codes when services fail before they are exec()ed
693 - document that service reload may be implemented as service reexec
694 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
695 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
696 - document systemd-journal-flush.service properly
697 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
698 - man: document the very specific env the shutdown drop-in tools live in
699 - man: add more examples to man pages
700 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
703 - add systemctl switch to dump transaction without executing it
704 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
705 - "systemctl disable" on a static unit prints no message and does
706 nothing. "systemctl enable" does nothing, and gives a bad message
707 about it. Should fix both to print nice actionable messages.
708 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
709 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
710 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
711 - systemctl: "Journal has been rotated since unit was started." message is misleading
712 - better error message if you run systemctl without systemd running
713 - systemctl status output should include list of triggering units and their status
716 - "systemctl mask" should find all names by which a unit is accessible
717 (i.e. by scanning for symlinks to it) and link them all to /dev/null
720 - timer units should get the ability to trigger when:
721 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
723 - Modulate timer frequency based on battery state
725 * add libsystemd-password or so to query passwords during boot using the password agent logic
727 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
729 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
731 * make repeated alt-ctrl-del presses printing a dump
733 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
735 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
738 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
739 with seccomp. That should provide us with a useful log buffer that
740 systemd can log to during early boot, and disconnect container logs
741 from the kernel's logs.
742 - as soon as networkd has a bus interface, hook up --network-interface=,
743 --network-bridge= with networkd, to trigger netdev creation should an
745 - a nice way to boot up without machine id set, so that it is set at boot
746 automatically for supporting --ephemeral. Maybe hash the host machine id
747 together with the machine name to generate the machine id for the container
748 - fix logic always print a final newline on output.
749 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
750 - should optionally support receiving WATCHDOG=1 messages from its payload
752 - should send out sd_notify("WATCHDOG=1") messages
753 - optionally automatically add FORWARD rules to iptables whenever nspawn is
754 running, remove them when shut down.
755 - Improve error message when --bind= is used on a non-existing source
757 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
761 - refuse mounting over a mount point
762 - automatically discover .roothash files in dissect, similarly to nspawn
765 - add an API so that libvirt-lxc can inform us about network interfaces being
766 removed or added to an existing machine
767 - "machinectl migrate" or similar to copy a container from or to a
768 difference host, via ssh
769 - introduce systemd-nspawn-ephemeral@.service, and hook it into
770 "machinectl start" with a new --ephemeral switch
771 - "machinectl status" should also show internal logs of the container in
773 - "machinectl list-images" should show os-release data, as well as
774 machine-info data (including deployment level)
775 - "machinectl history"
777 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
778 shell in it, and marks it read-only after use
781 - generate a nice warning if mkfs.btrfs is missing
784 - cryptsetup-generator: allow specification of passwords in crypttab itself
785 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
787 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
788 https://bugs.freedesktop.org/show_bug.cgi?id=54712
790 * create /sbin/init symlinks from the build system
792 * add a dependency on standard-conf.xml and other included files to man pages
794 * MountFlags=shared acts as MountFlags=slave right now.
796 * properly handle loop back mounts via fstab, especially regards to fsck/passno
798 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
803 - add trigger --subsystem-match=usb/usb_device device
804 - reimport udev db after MOVE events for devices without dev_t
806 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
808 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
811 - save coredump in Windows/Mozilla minidump format
812 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
814 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
816 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
818 * be able to specify a forced restart of service A where service B depends on, in case B
819 needs to be auto-respawned?
822 - apply "x" on "D" too (see patch from William Douglas)
824 - instead of ignoring unknown fields, reject them.
825 - creating new directories/subvolumes/fifos/device nodes
826 should not follow symlinks. None of the other adjustment or creation
827 calls follow symlinks.
829 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
831 * verify that the AF_UNIX sockets of a service in the fs still exist
832 when we start a service in order to avoid confusion when a user
833 assumes starting a service is enough to make it accessible
835 * Make it possible to set the keymap independently from the font on
836 the kernel cmdline. Right now setting one resets also the other.
838 * and a dbus call to generate target from current state
840 * write blog stories about:
841 - hwdb: what belongs into it, lsusb
842 - enabling dbus services
844 - how to make changes to sysctl and sysfs attributes
846 - how to pass throw-away units to systemd, or dynamically change properties of existing units
847 - testing with Harald's awesome test kit
849 - how to develop against journal browsing APIs
850 - the journal HTTP iface
851 - non-cgroup resource management
852 - dynamic resource management with cgroups
853 - refreshed, longer missions statement
854 - calendar time events
855 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
856 - how to create your own target
857 - instantiated apache, dovecot and so on
858 - hooking a script into various stages of shutdown/rearly booot
860 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
862 * dot output for --test showing the 'initial transaction'
865 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
866 log both units as UNIT=, so that journalctl -u triggers on both.
867 - generate better errors when people try to set transient properties
868 that are not supported...
869 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
870 - maybe introduce WantsMountsFor=? Usecase:
871 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
872 - recreate systemd's D-Bus private socket file on SIGUSR2
873 - move PAM code into its own binary
874 - when we automatically restart a service, ensure we restart its rdeps, too.
875 - hide PAM options in fragment parser when compile time disabled
876 - Support --test based on current system state
877 - 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().
878 - after deserializing sockets in socket.c we should reapply sockopts and things
879 - drop PID 1 reloading, only do reexecing (difficult: Reload()
880 currently is properly synchronous, Reexec() is weird, because we
881 cannot delay the response properly until we are back, so instead of
882 being properly synchronous we just keep open the fd and close it
883 when done. That means clients do not get a successful method reply,
884 but much rather a disconnect on success.
885 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
886 - when a bus name of a service disappears from the bus make sure to queue further activation requests
889 - allow port=0 in .socket units
890 - maybe introduce ExecRestartPre=
891 - add ReloadSignal= for configuring a reload signal to use
892 - implement Register= switch in .socket units to enable registration
893 in Avahi, RPC and other socket registration services.
894 - allow Type=simple with PIDFile=
895 https://bugzilla.redhat.com/show_bug.cgi?id=723942
896 - allow writing multiple conditions in unit files on one line
897 - load-fragment: when loading a unit file via a chain of symlinks
898 verify that it is not masked via any of the names traversed.
899 - introduce Type=pid-file
900 - introduce mix of BindTo and Requisite
901 - add a concept of RemainAfterExit= to scope units
902 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
905 - Make sure ID_PATH is always exported and complete for
906 network devices where possible, so we can safely rely
908 - check MTUBytes parsing (expecting size_t but we are using unsigned)
911 - add support for more attribute types
912 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
915 - add more keys to [Route] and [Address] sections
916 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
917 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
918 - add reduced [Link] support to .network files
919 - add Scope= parsing option for [Network]
920 - properly handle routerless dhcp leases
921 - work with non-Ethernet devices
922 - add support for more bond options
923 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
924 - the DHCP lease data (such as NTP/DNS) is still made available when
925 a carrier is lost on a link. It should be removed instantly.
926 - expose in the API the following bits:
927 - option 15, domain name and/or option 119, search list
928 - option 12, host name and/or option 81, fqdn
929 - option 123, 144, geolocation
930 - option 252, configure http proxy (PAC/wpad)
931 - provide a way to define a per-network interface default metric value
932 for all routes to it. possibly a second default for DHCP routes.
933 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
934 support Name=foo*|bar*|baz ?
935 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
936 - allow DUID/IAID to be customized, see issue #394.
937 - whenever uplink info changes, make DHCP server send out FORCERENEW
939 * networkd-wait-online:
940 - make operstates to wait for configurable?
943 - figure out how much we can increase Maximum Message Size
946 - add functions to set previously stored IPv6 addresses on startup and get
947 them at shutdown; store them in client->ia_na
948 - write more test cases
949 - implement reconfigure support, see 5.3., 15.11. and 22.20.
950 - implement support for temporary adressess (IA_TA)
951 - implement dhcpv6 authentication
952 - investigate the usefulness of Confirm messages; i.e. are there any
953 situations where the link changes without any loss in carrier detection
955 - some servers don't do rapid commit without a filled in IA_NA, verify
962 - natively watch for dbus-*.service symlinks (PENDING)
963 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
965 * fix alsa mixer restore to not print error when no config is stored
967 * make cryptsetup lower --iter-time
969 * patch kernel for xattr support in /dev, /proc/, /sys?
971 * kernel: add device_type = "fb", "fbcon" to class "graphics"
973 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
975 * /usr/bin/service should actually show the new command line
977 * 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=
979 * fedora: F20: go timer units all the way, leave cron.daily for cron
981 * neither pkexec nor sudo initialize environ[] from the PAM environment?
983 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
985 * register catalog database signature as file magic
987 * zsh shell completion:
988 - <command> <verb> -<TAB> should complete options, but currently does not
989 - systemctl add-wants,add-requires
994 * look for close() vs. close_nointr() vs. close_nointr_nofail()
996 * check for strerror(r) instead of strerror(-r)
998 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
1002 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1004 * use secure_getenv() instead of getenv() where appropriate
1006 * link up selected blog stories from man pages and unit files Documentation= fields
