3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
19 * wiki: update journal format documentation for lz4 additions
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
27 * make use of ethtool veth peer info in machined, for automatically finding out
28 host-side interface pointing to the container.
30 * add some special mode to LogsDirectory=/StateDirectory=… that allows
31 declaring these directories without necessarily pulling in deps for them, or
32 creating them when starting up. That way, we could declare that
33 systemd-journald writes to /var/log/journal, which could be useful when we
34 doing disk usage calculations and so on.
36 * taint systemd if there are fewer than 65536 users assigned to the system.
38 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
40 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
41 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
42 as the unit is running or has a job queued.
44 * hook up sd-bus' creds stuff with SO_PEERGROUPS
46 * add async version of sd_bus_add_match and make use of that
48 * support projid-based quota in machinectl for containers, and then drop
49 implicit btrfs loopback magic in machined
51 * Add NetworkNamespacePath= to specify a path to a network namespace
53 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
54 introduced) as the RTC epoch, instead of the mtime of NEWS.
56 * add a way to lock down cgroup migration: a boolean, which when set for a unit
57 makes sure the processes in it can never migrate out of it
59 * blog about fd store and restartable services
61 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
63 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
64 magic meaning and is no longer upgraded to something else if set explicitly.
66 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
67 make it lose its identity, i.e. be anonymous. For this we'd have to patch
68 through the whole tree to make all code deal with the case where no machine
71 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
72 suitable for processing with rrdtool. Add bus API to access this data, and
73 possibly implement a CPULoad property based on it.
75 * beef up pam_systemd to take unit file settings such as cgroups properties as
78 * a new "systemd-analyze security" tool outputting a checklist of security
79 features a service does and does not implement
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. Or
84 alternatively, do this with projids, so that we can also cover services
85 running as root. Quota should probably cover all the special dirs such as
86 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
87 is set, plus the whole disk space any image configured with RootImage=.
89 * Introduce "exit" as an EmergencyAction value, and allow to configure a
90 per-unit success/failure exit code to configure. This would be useful for
91 running commands inside of services inside of containers, which could then
92 propagate their failure state all the way up.
94 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
95 disks to see if the UID is already in use.
97 * add dissect_image_warn() as a wrapper around dissect_image() that prints
98 friendly log messages for the returned errors, so that we don't have to
99 duplicate that in nspawn, systemd-dissect and PID 1.
101 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
102 for all units. It should be both a way to pin units into memory as well as a
103 wait to retrieve their exit data.
105 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
106 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
107 automatically. For example, there could be $RUNTIME_DIRECTORY,
108 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
109 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
110 can adapt to varying directories for these purposes. Special care has to be
111 taken if multiple dirs are configured. Maybe avoid setting the env vars in
114 * expose IO accounting data on the bus, show it in systemd-run --wait and log
115 about it in the resource log message
117 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
118 unit when it is stopped
120 * show whether a service has out-of-date configuration in "systemctl status" by
121 using mtime data of ConfigurationDirectory=.
123 * replace all uses of fgets() + LINE_MAX by read_line()
125 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
126 creates a static, persistent user rather than a dynamic, transient user. We
127 can leverage code from sysusers.d for this.
129 * add some optional flag to ReadWritePaths= and friends, that has the effect
130 that we create the dir in question when the service is started. Example:
132 ReadWritePaths=:/var/lib/foobar
134 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
135 the sd-journal logging socket, and, if the timeout is set to 0, sets
136 O_NONBLOCK on it. That way people can control if and when to block for
139 * tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
140 PIDs not managed by the service manager)
142 * hostnamed: populate form factor data from a new hwdb database, so that old
143 yogas can be recognized as "convertible" too, even if they predate the DMI
144 "convertible" form factor
146 * Maybe add a small tool invoked early at boot, that adds in or resizes
147 partitions automatically, to be used when the media used is actually larger
148 than the image written onto it is.
150 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
151 after all. Be strict however, only support the equivalent of nspawn's
152 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
155 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
156 the service cgroup, which is supposed to monitor the service, and when it
157 exits the service is considered failed by its monitor.
159 * track the per-service PAM process properly (i.e. as an additional control
160 process), so that it may be queried on the bus and everything.
162 * add a new "debug" job mode, that is propagated to unit_start() and for
163 services results in two things: we raise SIGSTOP right before invoking
164 execve() and turn off watchdog support. Then, use that to implement
165 "systemd-gdb" for attaching to the start-up of any system service in its
168 * replace all canonicalize_file_name() invocations by chase_symlinks(), in
169 particulr those where a rootdir is relevant.
171 * maybe introduce gpt auto discovery for /var/tmp?
173 * maybe add gpt-partition-based user management: each user gets his own
174 LUKS-encrypted GPT partition with a new GPT type. A small nss module
175 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
176 way: the partition index is added as offset to some fixed base uid. User name
177 is stored in GPT partition name. A PAM module authenticates the user via the
178 LUKS partition password. Benefits: strong per-user security, compatibility
179 with stateless/read-only/verity-enabled root. (other idea: do this based on
180 loopback files in /home, without GPT involvement)
182 * gpt-auto logic: introduce support for discovering /var matching an image. For
183 that, use a partition type UUID that is hashed from the OS name (as encoded
184 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
185 field of the root partition. This way can easily support multiple OS
186 installations on the same GPT partition table, without problems with
187 unmatched /var partitions.
189 * gpt-auto logic: related to the above, maybe support a "secondary" root
190 partition, that is mounted to / and is writable, and where the actual root's
191 /usr is mounted into.
193 * 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
195 * drop nss-myhostname in favour of nss-resolve?
197 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
198 then use that for the setting used in user@.service. It should be understood
199 relative to the configured default value.
201 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
203 * enable LockMLOCK to take a percentage value relative to physical memory
205 * Permit masking specific netlink APIs with RestrictAddressFamily=
207 * nspawn: support that /proc, /sys/, /dev are pre-mounted
209 * define gpt header bits to select volatility mode
211 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
213 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
215 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
217 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
219 * ProtectKeyRing= to take keyring calls away
221 * RemoveKeyRing= to remove all keyring entries of the specified user
223 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
224 on PID 1 with the relevant signals, and makes relevant files in /sys and
225 /proc (such as the sysrq stuff) unavailable
227 * DeviceAllow= should also generate seccomp filters for mknod()
229 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
231 * journalctl: make sure -f ends when the container indicated by -M terminates
233 * mount: automatically search for "main" partition of an image has multiple
236 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
239 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
240 find a way to map the User=/Group= of the service to the right name. This way
241 a user/group for a service only has to exist on the host for the right
244 * add bus API for creating unit files in /etc, reusing the code for transient units
246 * add bus API to remove unit files from /etc
248 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
250 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
251 kernel doesn't support linkat() that replaces existing files, currently)
253 * check if DeviceAllow= should split first, resolve specifiers later
255 * transient units: don't bother with actually setting unit properties, we
256 reload the unit file anyway
258 * journald: sigbus API via a signal-handler safe function that people may call
259 from the SIGBUS handler
261 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
263 * resolved: when routing queries, make sure only look for the *longest* suffix...
265 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
266 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
268 * cache sd_event_now() result from before the first iteration...
270 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
272 * PID1: find a way how we can reload unit file configuration for
273 specific units only, without reloading the whole of systemd
275 * add an explicit parser for LimitRTPRIO= that verifies
276 the specified range and generates sane error messages for incorrect
279 * when we detect that there are waiting jobs but no running jobs, do something
281 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
283 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
285 * there's probably something wrong with having user mounts below /sys,
286 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
287 prefixed with /sys generally special.
288 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
290 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
292 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
294 * mounting and unmounting mount points manually with different source
295 devices will result in collected on all devices used.
296 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
298 * add a job mode that will fail if a transaction would mean stopping
299 running units. Use this in timedated to manage the NTP service
301 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
303 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
304 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
306 * The udev blkid built-in should expose a property that reflects
307 whether media was sensed in USB CF/SD card readers. This should then
308 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
309 picked up by systemd unless they contain a medium. This would mirror
310 the behaviour we already have for CD drives.
312 * networkd/udev: implement SR_IOV configuration in .link files:
313 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
315 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
317 * Port various tools to make use of verbs.[ch], where applicable: busctl,
318 coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
320 * hostnamectl: show root image uuid
322 * sysfs set api in libudev is not const
324 * Find a solution for SMACK capabilities stuff:
325 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
327 * "systemctl preset-all" should probably order the unit files it
328 operates on lexicographically before starting to work, in order to
329 ensure deterministic behaviour if two unit files conflict (like DMs
332 * synchronize console access with BSD locks:
333 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
335 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
336 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
338 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
340 * figure out when we can use the coarse timers
342 * add "systemctl start -v foobar.service" that shows logs of a service
343 while the start command runs. This is non-trivial to do without
344 races though, since we should flush out all journal messages before
345 returning from the "systemctl stop".
347 * 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
349 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
351 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
353 * consider showing the unit names during boot up in the status output, not just the unit descriptions
355 * maybe allow timer units with an empty Units= setting, so that they
356 can be used for resuming the system but nothing else.
358 * what to do about udev db binary stability for apps? (raw access is not an option)
360 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
362 * man: maybe use the word "inspect" rather than "introspect"?
364 * systemctl: if some operation fails, show log output?
366 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
367 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
369 * exponential backoff in timesyncd when we cannot reach a server
371 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
373 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
375 * systemd.show_status= should probably have a mode where only failed
378 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
379 (throughout the codebase, not only PID1)
383 - service registration
384 - service/domain/types browsing
386 - DNS-SD service registration from socket units
387 - resolved should optionally register additional per-interface LLMNR
388 names, so that for the container case we can establish the same name
389 (maybe "host") for referencing the server, everywhere.
390 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
391 - hook up resolved with machined-based address resolution
393 * refcounting in sd-resolve is borked
395 * Add a new verb "systemctl top"
397 * add new gpt type for btrfs volumes
399 * support empty /etc boots nicely:
400 - nspawn/gpt-generator: introduce new gpt partition type for /usr
402 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
404 * a way for container managers to turn off getty starting via $container_headless= or so...
406 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
408 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
409 they run added to the initial transaction and thus confuse Type=idle.
411 * add bus api to query unit file's X fields.
413 * gpt-auto-generator:
414 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
415 - Make /home automount rather than mount?
417 * add generator that pulls in systemd-network from containers when
418 CAP_NET_ADMIN is set, more than the loopback device is defined, even
419 when it is otherwise off
421 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
423 * implement Distribute= in socket units to allow running multiple
424 service instances processing the listening socket, and open this up
427 * socket units: support creating sockets in different namespace,
428 opening it up for JoinsNamespaceOf=. This would require to fork off
429 a tiny process that joins the namespace and creates/binds the socket
430 and passes this back to PID1 via SCM_RIGHTS. This also could be used
431 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
433 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
434 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
435 should SIGSTOP all unit processes in a loop until all processes of
436 it are fully stopped. This can later be used for app management by
437 desktop UIs such as gnome-shell to freeze apps that are not visible
438 on screen, not unlike how job control works on the shell
441 - implement per-slice CPUFairScheduling=1 switch
442 - handle jointly mounted controllers correctly
443 - introduce high-level settings for RT budget, swappiness
444 - how to reset dynamically changed unit cgroup attributes sanely?
445 - when reloading configuration, apply new cgroup configuration
446 - when recursively showing the cgroup hierarchy, optionally also show
447 the hierarchies of child processes
450 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
451 - ensure scope units may be started only a single time
453 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
455 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
457 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
459 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
461 * 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
463 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
465 * If we try to find a unit via a dangling symlink, generate a clean
466 error. Currently, we just ignore it and read the unit from the search
469 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
471 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
473 * load .d/*.conf dropins for device units
475 * allow implementation of InaccessibleDirectories=/ plus
476 ReadOnlyDirectories=... for whitelisting files for a service.
480 - GetAllProperties() on a non-existing object does not result in a failure currently
481 - port to sd-resolve for connecting to TCP dbus servers
482 - 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
483 - see if we can drop more message validation on the sending side
484 - add API to clone sd_bus_message objects
485 - make AddMatch calls on dbus1 transports async?
486 - longer term: priority inheritance
488 - NameLost/NameAcquired obsolete
491 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
492 - test bloom filter generation indexes
495 - allow multiple signal handlers per signal?
496 - document chaining of signal handler for SIGCHLD and child handlers
497 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
498 - generate a failure of a default event loop is executed out-of-thread
499 - maybe add support for inotify events
501 * investigate endianness issues of UUID vs. GUID
503 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
504 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
506 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
508 * add a pam module that on password changes updates any LUKS slot where the password matches
510 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
513 - add 'set -e' to scripts in test/
514 - make stuff in test/ work with separate output dir
516 * seems that when we follow symlinks to units we prefer the symlink
517 destination path over /etc and /usr. We should not do that. Instead
518 /etc should always override /run+/usr and also any symlink
521 * when isolating, try to figure out a way how we implicitly can order
522 all units we stop before the isolating unit...
524 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
526 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
527 that the boot loader should be installed to the ESP. Define a way
528 how an installer can figure out whether a BLS compliant boot loader
531 * think about requeuing jobs when daemon-reload is issued? usecase:
532 the initrd issues a reload after fstab from the host is accessible
533 and we might want to requeue the mounts local-fs acquired through
536 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
538 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
540 * shutdown logging: store to EFI var, and store to USB stick?
542 * merge unit_kill_common() and unit_kill_context()
544 * introduce ExecCondition= in services
547 - honor language efi variables for default language selection (if there are any?)
548 - honor timezone efi variables for default timezone selection (if there are any?)
549 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
551 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
553 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
555 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
558 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
559 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
560 - logind: wakelock/opportunistic suspend support
561 - Add pretty name for seats in logind
562 - logind: allow showing logout dialog from system?
563 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
564 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
565 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
566 - if pam_systemd is invoked by su from a process that is outside of a
567 any session we should probably just become a NOP, since that's
568 usually not a real user session but just some system code that just
570 - logind: make the Suspend()/Hibernate() bus calls wait for the for
571 the job to be completed. before returning, so that clients can wait
572 for "systemctl suspend" to finish to know when the suspending is
574 - logind: when the power button is pressed short, just popup a
575 logout dialog. If it is pressed for 1s, do the usual
576 shutdown. Inspiration are Macs here.
577 - expose "Locked" property on logind sesison objects
578 - given that logind now lets PID 1 do all nasty work, we can
579 probably reduce the capability set it retains substantially.
580 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
581 - expose orientation sensors and tablet mode through logind
582 - maybe allow configuration of the StopTimeout for session scopes
583 - rename session scope so that it includes the UID. THat way
584 the session scope can be arranged freely in slices and we don't have
585 make assumptions about their slice anymore.
586 - follow PropertiesChanged state more closely, to deal with quick logouts and
589 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
591 * service: watchdog logic: for testing purposes allow ping, but do not require pong
594 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
595 - import and delete pstore filesystem content at startup
596 - journald: also get thread ID from client, plus thread name
597 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
598 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
599 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
600 - declare the local journal protocol stable in the wiki interface chart
601 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
602 - journald: when dropping msgs due to ratelimit make sure to write
603 "dropped %u messages" not only when we are about to print the next
604 message that works, but alraedy after a short tiemout
605 - check if we can make journalctl by default use --follow mode inside of less if called without args?
606 - maybe add API to send pairs of iovecs via sd_journal_send
607 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
608 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
609 and !FOOBAR for events without FOOBAR.
610 - journal: store timestamp of journal_file_set_offline() int he header,
611 so it is possible to display when the file was last synced.
612 - 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.
613 - journal: find a way to allow dropping history early, based on priority, other rules
614 - journal: When used on NFS, check payload hashes
615 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
616 - refuse taking lower-case variable names in sd_journal_send() and friends.
617 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
618 - journal: deal nicely with byte-by-byte copied files, especially regards header
619 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
620 - Replace utmp, wtmp, btmp, and lastlog completely with journal
621 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
622 - when a kernel driver logs in a tight loop, we should ratelimit that too.
623 - journald: optionally, log debug messages to /run but everything else to /var
624 - journald: when we drop syslog messages because the syslog socket is
625 full, make sure to write how many messages are lost as first thing
626 to syslog when it works again.
627 - change systemd-journal-flush into a service that stays around during
628 boot, and causes the journal to be moved back to /run on shutdown,
629 so that we do not keep /var busy. This needs to happen synchronously,
630 hence doing this via signals is not going to work.
631 - optionally support running journald from the command line for testing purposes in external projects
632 - journald: allow per-priority and per-service retention times when rotating/vacuuming
633 - journald: make use of uid-range.h to managed uid ranges to split
635 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
636 - improve journalctl performance by loading journal files
637 lazily. Encode just enough information in the file name, so that we
638 do not have to open it to know that it is not interesting for us, for
639 the most common operations.
640 - journal-or-kmsg is currently broken? See reverted
641 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
642 - man: document that corrupted journal files is nothing to act on
643 - rework journald sigbus stuff to use mutex
644 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
645 services that run under their own user ids, and use User= (but only
646 in a world where userns is ubiquitous since otherwise we cannot
647 invoke those daemons on the host AND in a container anymore). Also,
648 if LimitNPROC= is used without User= we should warn and refuse
650 - journalctl --verify: don't show files that are currently being
651 written to as FAIL, but instead show that their are being written to.
652 - add journalctl -H that talks via ssh to a remote peer and passes through
654 - add a version of --merge which also merges /var/log/journal/remote
655 - journalctl: -m should access container journals directly by enumerating
656 them via machined, and also watch containers coming and going.
657 Benefit: nspawn --ephemeral would start working nicely with the journal.
658 - assign MESSAGE_ID to log messages about failed services
660 * add a test if all entries in the catalog are properly formatted.
661 (Adding dashes in a catalog entry currently results in the catalog entry
662 being silently skipped. journalctl --update-catalog must warn about this,
663 and we should also have a unit test to check that all our message are OK.)
666 - document that deps in [Unit] sections ignore Alias= fields in
667 [Install] units of other units, unless those units are disabled
668 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
669 - document that service reload may be implemented as service reexec
670 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
671 - document systemd-journal-flush.service properly
672 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
673 - man: document the very specific env the shutdown drop-in tools live in
674 - man: add more examples to man pages
675 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
678 - add systemctl switch to dump transaction without executing it
679 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
680 - "systemctl disable" on a static unit prints no message and does
681 nothing. "systemctl enable" does nothing, and gives a bad message
682 about it. Should fix both to print nice actionable messages.
683 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
684 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
685 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
686 - systemctl: "Journal has been rotated since unit was started." message is misleading
687 - systemctl status output should include list of triggering units and their status
690 - "systemctl mask" should find all names by which a unit is accessible
691 (i.e. by scanning for symlinks to it) and link them all to /dev/null
694 - timer units should get the ability to trigger when:
695 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
697 - Modulate timer frequency based on battery state
699 * add libsystemd-password or so to query passwords during boot using the password agent logic
701 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
703 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
705 * make repeated alt-ctrl-del presses printing a dump
707 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
709 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
712 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
713 with seccomp. That should provide us with a useful log buffer that
714 systemd can log to during early boot, and disconnect container logs
715 from the kernel's logs.
716 - as soon as networkd has a bus interface, hook up --network-interface=,
717 --network-bridge= with networkd, to trigger netdev creation should an
719 - a nice way to boot up without machine id set, so that it is set at boot
720 automatically for supporting --ephemeral. Maybe hash the host machine id
721 together with the machine name to generate the machine id for the container
722 - fix logic always print a final newline on output.
723 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
724 - should optionally support receiving WATCHDOG=1 messages from its payload
726 - optionally automatically add FORWARD rules to iptables whenever nspawn is
727 running, remove them when shut down.
728 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
732 - refuse mounting over a mount point
733 - automatically discover .roothash files in dissect, similarly to nspawn
736 - add an API so that libvirt-lxc can inform us about network interfaces being
737 removed or added to an existing machine
738 - "machinectl migrate" or similar to copy a container from or to a
739 difference host, via ssh
740 - introduce systemd-nspawn-ephemeral@.service, and hook it into
741 "machinectl start" with a new --ephemeral switch
742 - "machinectl status" should also show internal logs of the container in
744 - "machinectl list-images" should show os-release data, as well as
745 machine-info data (including deployment level)
746 - "machinectl history"
748 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
749 shell in it, and marks it read-only after use
752 - generate a nice warning if mkfs.btrfs is missing
755 - cryptsetup-generator: allow specification of passwords in crypttab itself
756 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
758 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
759 https://bugs.freedesktop.org/show_bug.cgi?id=54712
761 * create /sbin/init symlinks from the build system
763 * add a dependency on standard-conf.xml and other included files to man pages
765 * MountFlags=shared acts as MountFlags=slave right now.
767 * properly handle loop back mounts via fstab, especially regards to fsck/passno
769 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
774 - add trigger --subsystem-match=usb/usb_device device
775 - reimport udev db after MOVE events for devices without dev_t
777 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
779 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
782 - save coredump in Windows/Mozilla minidump format
783 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
785 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
787 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
789 * be able to specify a forced restart of service A where service B depends on, in case B
790 needs to be auto-respawned?
793 - apply "x" on "D" too (see patch from William Douglas)
795 - instead of ignoring unknown fields, reject them.
796 - creating new directories/subvolumes/fifos/device nodes
797 should not follow symlinks. None of the other adjustment or creation
798 calls follow symlinks.
800 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
802 * verify that the AF_UNIX sockets of a service in the fs still exist
803 when we start a service in order to avoid confusion when a user
804 assumes starting a service is enough to make it accessible
806 * Make it possible to set the keymap independently from the font on
807 the kernel cmdline. Right now setting one resets also the other.
809 * and a dbus call to generate target from current state
811 * write blog stories about:
812 - hwdb: what belongs into it, lsusb
813 - enabling dbus services
814 - how to make changes to sysctl and sysfs attributes
816 - how to pass throw-away units to systemd, or dynamically change properties of existing units
817 - testing with Harald's awesome test kit
819 - how to develop against journal browsing APIs
820 - the journal HTTP iface
821 - non-cgroup resource management
822 - dynamic resource management with cgroups
823 - refreshed, longer missions statement
824 - calendar time events
825 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
826 - how to create your own target
827 - instantiated apache, dovecot and so on
828 - hooking a script into various stages of shutdown/rearly booot
830 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
832 * dot output for --test showing the 'initial transaction'
835 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
836 log both units as UNIT=, so that journalctl -u triggers on both.
837 - generate better errors when people try to set transient properties
838 that are not supported...
839 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
840 - maybe introduce WantsMountsFor=? Usecase:
841 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
842 - recreate systemd's D-Bus private socket file on SIGUSR2
843 - move PAM code into its own binary
844 - when we automatically restart a service, ensure we restart its rdeps, too.
845 - hide PAM options in fragment parser when compile time disabled
846 - Support --test based on current system state
847 - 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().
848 - after deserializing sockets in socket.c we should reapply sockopts and things
849 - drop PID 1 reloading, only do reexecing (difficult: Reload()
850 currently is properly synchronous, Reexec() is weird, because we
851 cannot delay the response properly until we are back, so instead of
852 being properly synchronous we just keep open the fd and close it
853 when done. That means clients do not get a successful method reply,
854 but much rather a disconnect on success.
855 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
856 - when a bus name of a service disappears from the bus make sure to queue further activation requests
859 - allow port=0 in .socket units
860 - maybe introduce ExecRestartPre=
861 - add ReloadSignal= for configuring a reload signal to use
862 - implement Register= switch in .socket units to enable registration
863 in Avahi, RPC and other socket registration services.
864 - allow Type=simple with PIDFile=
865 https://bugzilla.redhat.com/show_bug.cgi?id=723942
866 - allow writing multiple conditions in unit files on one line
867 - load-fragment: when loading a unit file via a chain of symlinks
868 verify that it is not masked via any of the names traversed.
869 - introduce Type=pid-file
870 - introduce mix of BindTo and Requisite
871 - add a concept of RemainAfterExit= to scope units
872 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
875 - Make sure ID_PATH is always exported and complete for
876 network devices where possible, so we can safely rely
878 - check MTUBytes parsing (expecting size_t but we are using unsigned)
881 - add support for more attribute types
882 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
885 - add more keys to [Route] and [Address] sections
886 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
887 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
888 - add reduced [Link] support to .network files
889 - add Scope= parsing option for [Network]
890 - properly handle routerless dhcp leases
891 - work with non-Ethernet devices
892 - add support for more bond options
893 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
894 - the DHCP lease data (such as NTP/DNS) is still made available when
895 a carrier is lost on a link. It should be removed instantly.
896 - expose in the API the following bits:
897 - option 15, domain name and/or option 119, search list
898 - option 12, host name and/or option 81, fqdn
899 - option 123, 144, geolocation
900 - option 252, configure http proxy (PAC/wpad)
901 - provide a way to define a per-network interface default metric value
902 for all routes to it. possibly a second default for DHCP routes.
903 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
904 support Name=foo*|bar*|baz ?
905 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
906 - allow DUID/IAID to be customized, see issue #394.
907 - whenever uplink info changes, make DHCP server send out FORCERENEW
909 * networkd-wait-online:
910 - make operstates to wait for configurable?
913 - figure out how much we can increase Maximum Message Size
916 - add functions to set previously stored IPv6 addresses on startup and get
917 them at shutdown; store them in client->ia_na
918 - write more test cases
919 - implement reconfigure support, see 5.3., 15.11. and 22.20.
920 - implement support for temporary adressess (IA_TA)
921 - implement dhcpv6 authentication
922 - investigate the usefulness of Confirm messages; i.e. are there any
923 situations where the link changes without any loss in carrier detection
925 - some servers don't do rapid commit without a filled in IA_NA, verify
932 - natively watch for dbus-*.service symlinks (PENDING)
933 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
935 * fix alsa mixer restore to not print error when no config is stored
937 * make cryptsetup lower --iter-time
939 * patch kernel for xattr support in /dev, /proc/, /sys?
941 * kernel: add device_type = "fb", "fbcon" to class "graphics"
943 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
945 * /usr/bin/service should actually show the new command line
947 * 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=
949 * fedora: F20: go timer units all the way, leave cron.daily for cron
951 * neither pkexec nor sudo initialize environ[] from the PAM environment?
953 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
955 * register catalog database signature as file magic
957 * zsh shell completion:
958 - <command> <verb> -<TAB> should complete options, but currently does not
959 - systemctl add-wants,add-requires
964 * look for close() vs. close_nointr() vs. close_nointr_nofail()
966 * check for strerror(r) instead of strerror(-r)
970 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
972 * use secure_getenv() instead of getenv() where appropriate
974 * link up selected blog stories from man pages and unit files Documentation= fields
