3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
15 * When systemctl --host is used, underlying ssh connection can remain open.
16 bus_close does not kill children?
20 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
22 * wiki: update journal format documentation for lz4 additions
26 * code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
28 * replace manual readdir() loops with FOREACH_DIRENT or FOREACH_DIRENT_ALL
30 * Get rid of the last strerror() invocations in favour of %m and strerror_r()
32 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
36 * PID1: find a way how we can reload unit file configuration for
37 specific units only, without reloading the whole of systemd
39 * add an explicit parser for LimitNICE= and LimitRTPRIO= that verifies
40 the specified range and generates sane error messages for incorrect
41 specifications. Also, for LimitNICE= maybe introduce a syntax such
42 as "+5" or "-7" in order to make the limits more readable as they
43 are otherwise shifted by 20.
45 * do something about "/control" subcgroups in the unified cgroup hierarchy
47 * when we detect that there are waiting jobs but no running jobs, do something
49 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
51 * add a concept of RemainAfterExit= to scope units
53 * add a new command "systemctl revert" or so, that removes all dropin
54 snippets in /run and /etc, and all unit files with counterparts in
55 /usr, and thus undoes what "systemctl set-property" and "systemctl
56 edit" create. Maybe even add "systemctl revert -a" to do this for
59 * sd-event: maybe add support for inotify events
61 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
63 * nspawn should send out sd_notify("WATCHDOG=1") messages
65 * nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
67 * consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
69 * "systemctl edit" should know a mode to create a new unit file
71 * there's probably something wrong with having user mounts below /sys,
72 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
73 prefixed with /sys generally special.
74 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
76 * nspawn: fix logic always print a final newline on output.
77 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
79 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
81 * "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
83 * install: include generator dirs in unit file search paths
85 * logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
87 * invent a better systemd-run scheme for naming scopes, that works with remoting
89 * add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
91 * change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
93 * add a version of --merge which also merges /var/log/journal/remote
95 * log accumulated resource usage after each service invocation
97 * nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container
99 * logind: rename session scope so that it includes the UID. THat way
100 the session scope can be arranged freely in slices and we don't have
101 make assumptions about their slice anymore.
103 * journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal.
105 * nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
107 * nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
109 * importd: generate a nice warning if mkfs.btrfs is missing
111 * nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers
113 * nspawn: Improve error message when --bind= is used on a non-existing source directory
115 * nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
117 * man: document how update dkr images works with machinectl
118 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
120 * nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing
122 * rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
123 to unicode chars, to make things more expressive.
125 * "machinectl migrate" or similar to copy a container from or to a
126 difference host, via ssh
128 * tmpfiles: creating new directories/subvolumes/fifos/device nodes
129 should not follow symlinks. None of the other adjustment or creation
130 calls follow symlinks.
132 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
134 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
136 * mounting and unmounting mount points manually with different source
137 devices will result in collected collected on all devices used.
138 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
140 * add a job mode that will fail if a transaction would mean stopping
141 running units. Use this in timedated to manage the NTP service
143 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
145 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
146 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
148 * .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
150 * When logging about multiple units (stopping BoundTo units, conflicts, etc.),
151 log both units as UNIT=, so that journalctl -u triggers on both.
153 * to allow "linking" of nspawn containers, extend --network-bridge= so
154 that it can dynamically create bridge interfaces that are refcounted
155 by the containers on them. For each group of containers to link together
157 * journalctl --verify: don't show files that are currently being
158 written to as FAIL, but instead show that their are being written
161 * assign MESSAGE_ID to log messages about failed services
163 * coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
164 and supress coredump if turned off. Then change RLIMIT_CORE to
165 infinity by default for all services. This then allows per-service
166 control of coredumping.
168 * generate better errors when people try to set transient properties
169 that are not supported...
170 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
172 * maybe introduce WantsMountsFor=? Usecase:
173 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
175 * The udev blkid built-in should expose a property that reflects
176 whether media was sensed in USB CF/SD card readers. This should then
177 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
178 picked up by systemd unless they contain a medium. This would mirror
179 the behaviour we already have for CD drives.
181 * nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
182 with seccomp. That should provide us with a useful log buffer that
183 systemd can log to during early boot, and disconnect container logs
184 from the kernel's logs.
186 * networkd/udev: implement SR_IOV configuration in .link files:
187 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
189 * Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
190 services that run under their own user ids, and use User= (but only
191 in a world where userns is ubiquitous since otherwise we cannot
192 invoke those daemons on the host AND in a container anymore). Also,
193 if LimitNPROC= is used without User= we should warn and refuse
196 * logind: maybe allow configuration of the StopTimeout for session scopes
198 * Set NoNewPrivileges= on all of our own services, where that makes sense
200 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
202 * rework journald sigbus stuff to use mutex
204 * import-dkr: support tarsum checksum verification, if it becomes reality one day...
206 * import-dkr: convert json bits to nspawn configuration
208 * core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall
210 * introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
212 * "machinectl status" should also show internal logs of the container in question
214 * "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
216 * Port various tools to make use of verbs.[ch], where applicable
218 * "machinectl history"
222 * "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
224 * systemd-nspawn -x should support ephemeral instances of gpt images
226 * hostnamectl: show root image uuid
228 * sysfs set api in libudev is not const
230 * Find a solution for SMACK capabilities stuff:
231 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
233 * "systemctl preset-all" should probably order the unit files it
234 operates on lexicographically before starting to work, in order to
235 ensure deterministic behaviour if two unit files conflict (like DMs
238 * resolved should optionally register additional per-interface LLMNR
239 names, so that for the container case we can establish the same name
240 (maybe "host") for referencing the server, everywhere.
242 * systemd-journal-upload (or a new, related tool): allow pushing out
243 journal messages onto the network in BSD syslog protocol,
244 continuously. Default to some link-local IP mcast group, to make this
245 useful as a one-stop debugging tool.
247 * synchronize console access with BSD locks:
248 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
250 * as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
251 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
253 * the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
255 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
257 * figure out when we can use the coarse timers
259 * add "systemctl start -v foobar.service" that shows logs of a service
260 while the start command runs. This is non-trivial to do without
261 races though, since we should flush out all journal messages before
262 returning from the "systemctl stop".
264 * 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
266 * timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
268 * add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
270 * machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
272 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
274 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
276 * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
278 * consider showing the unit names during boot up in the status output, not just the unit descriptions
280 * dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
282 * maybe allow timer units with an empty Units= setting, so that they
283 can be used for resuming the system but nothing else.
285 * what to do about udev db binary stability for apps? (raw access is not an option)
287 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
289 * maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
291 * man: document that corrupted journal files is nothing to act on
293 * man: maybe use the word "inspect" rather than "introspect"?
295 * "machinectl list" should probably show columns for OS version and IP addresses
297 * systemctl: if some operation fails, show log output?
300 - allow creation of units from scratch
301 - use equvalent of cat() to insert existing config as a comment, prepended with #.
302 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
304 * refcounting in sd-resolve is borked
306 * exponential backoff in timesyncd and resolved when we cannot reach a server
308 * extract_many_words() should probably be used by a lot of code that
309 currently uses FOREACH_WORD and friends. For example, most conf
310 parsing callbacks should use it.
312 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
314 * systemd.show_status= should probably have a mode where only failed
317 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
318 (throughout the codebase, not only PID1)
321 - add LLDP client side support
322 - the DHCP lease data (such as NTP/DNS) is still made available when
323 a carrier is lost on a link. It should be removed instantly.
324 - expose in the API the following bits:
325 - option 15, domain name and/or option 119, search list
326 - option 12, host name and/or option 81, fqdn
327 - option 123, 144, geolocation
328 - option 252, configure http proxy (PAC/wpad)
329 - provide a way to define a per-network interface default metric value
330 for all routes to it. possibly a second default for DHCP routes.
331 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
332 support Name=foo*|bar*|baz ?
333 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
334 - allow DUID/IAID to be customized, see issue #394.
335 - support configuration option for TSO (tcp segmentation offload)
336 - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW
339 - put networkd events and rtnl events at a higher priority, so that
340 we always process them before we process client requests
342 - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
347 - DNS-SD service registration from socket units
349 - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
350 announce dname support. However, for DNSSEC it is necessary as the synthesized cname
354 * Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
356 * Add a new verb "systemctl top"
358 * add new gpt type for btrfs volumes
360 * support empty /etc boots nicely:
361 - nspawn/gpt-generator: introduce new gpt partition type for /usr
362 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
364 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
366 * timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
368 * a way for container managers to turn off getty starting via $container_headless= or so...
370 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
372 * mount_cgroup_controllers(): symlinks need to get the label applied
374 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
375 they run added to the initial transaction and thus confuse Type=idle.
377 * Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
379 * sd-event: generate a failure of a default event loop is executed out-of-thread
381 * add bus api to query unit file's X fields.
383 * consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
385 * sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
387 * gpt-auto-generator:
388 - Support LUKS for root devices
389 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
390 - Make /home automount rather than mount?
392 * add generator that pulls in systemd-network from containers when
393 CAP_NET_ADMIN is set, more than the loopback device is defined, even
394 when it is otherwise off
396 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
398 * "busctl status" works only as root on dbus1, since we cannot read
401 * implement Distribute= in socket units to allow running multiple
402 service instances processing the listening socket, and open this up
405 * socket units: support creating sockets in different namespace,
406 opening it up for JoinsNamespaceOf=. This would require to fork off
407 a tiny process that joins the namespace and creates/binds the socket
408 and passes this back to PID1 via SCM_RIGHTS. This also could be used
409 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
411 * New service property: maximum CPU and wallclock runtime for a service
413 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
414 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
415 should SIGSTOP all unit processes in a loop until all processes of
416 it are fully stopped. This can later be used for app management by
417 desktop UIs such as gnome-shell to freeze apps that are not visible
418 on screen, not unlike how job control works on the shell
421 - implement per-slice CPUFairScheduling=1 switch
422 - handle jointly mounted controllers correctly
423 - introduce high-level settings for RT budget, swappiness
424 - how to reset dynamically changed unit cgroup attributes sanely?
425 - when reloading configuration, apply new cgroup configuration
426 - when recursively showing the cgroup hierarchy, optionally also show
427 the hierarchies of child processes
430 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
431 - ensure scope units may be started only a single time
433 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
435 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
437 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
439 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
441 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
443 * unify dispatch table in systemctl_main() and friends
445 * 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
447 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
449 * If we try to find a unit via a dangling symlink, generate a clean
450 error. Currently, we just ignore it and read the unit from the search
453 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
455 * btrfs raid assembly: some .device jobs stay stuck in the queue
457 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
459 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
461 * load .d/*.conf dropins for device units
463 * allow implementation of InaccessibleDirectories=/ plus
464 ReadOnlyDirectories=... for whitelisting files for a service.
468 - GetAllProperties() on a non-existing object does not result in a failure currently
469 - kdbus: process fd=-1 for incoming msgs
470 - port to sd-resolve for connecting to TCP dbus servers
471 - kdbus: maybe add controlling tty metadata fields
472 - 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
473 - when kdbus does not take our message without memfds, try again with memfds
474 - see if we can drop more message validation on the sending side
475 - add API to clone sd_bus_message objects
476 - make AddMatch calls on dbus1 transports async?
477 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
478 - longer term: priority inheritance
481 - NameLost/NameAcquired obsolete
484 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
485 - test bloom filter generation indexes
486 - bus-proxy: when passing messages from kdbus, make sure we properly
487 handle the case where a large number of fds is appended that we
488 cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
490 - kdbus: introduce a concept of "send-only" connections
491 - kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
494 - allow multiple signal handlers per signal?
495 - document chaining of signal handler for SIGCHLD and child handlers
497 * in the final killing spree, detect processes from the root directory, and
498 complain loudly if they have argv[0][0] == '@' set.
499 https://bugzilla.redhat.com/show_bug.cgi?id=961044
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...
512 * cgtop: make cgtop useful in a container
515 - add 'set -e' to scripts in test/
516 - make stuff in test/ work with separate output dir
518 * seems that when we follow symlinks to units we prefer the symlink
519 destination path over /etc and /usr. We should not do that. Instead
520 /etc should always override /run+/usr and also any symlink
523 * when isolating, try to figure out a way how we implicitly can order
524 all units we stop before the isolating unit...
526 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
528 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
529 that the boot loader should be installed to the ESP. Define a way
530 how an installer can figure out whether a BLS compliant boot loader
533 * think about requeuing jobs when daemon-reload is issued? usecase:
534 the initrd issues a reload after fstab from the host is accessible
535 and we might want to requeue the mounts local-fs acquired through
538 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
540 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
542 * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
544 * shutdown logging: store to EFI var, and store to USB stick?
546 * write UI tool that pops up emergency messages from the journal as notification
548 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
550 * merge unit_kill_common() and unit_kill_context()
552 * introduce ExecCondition= in services
555 - honor language efi variables for default language selection (if there are any?)
556 - honor timezone efi variables for default timezone selection (if there are any?)
557 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
559 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
561 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
563 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
566 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
567 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
568 - logind: wakelock/opportunistic suspend support
569 - Add pretty name for seats in logind
570 - logind: allow showing logout dialog from system?
571 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
572 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
573 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
574 - if pam_systemd is invoked by su from a process that is outside of a
575 any session we should probably just become a NOP, since that's
576 usually not a real user session but just some system code that just
578 - logind: make the Suspend()/Hibernate() bus calls wait for the for
579 the job to be completed. before returning, so that clients can wait
580 for "systemctl suspend" to finish to know when the suspending is
582 - logind: when the power button is pressed short, just popup a
583 logout dialog. If it is pressed for 1s, do the usual
584 shutdown. Inspiration are Macs here.
585 - expose "Locked" property on logind sesison objects
586 - given that logind now lets PID 1 do all nasty work, we can
587 probably reduce the capability set it retains substantially.
588 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
589 - expose orientation sensors and tablet mode through logind
591 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
593 * service: watchdog logic: for testing purposes allow ping, but do not require pong
596 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
597 - import and delete pstore filesystem content at startup
598 - journald: also get thread ID from client, plus thread name
599 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
600 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
601 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
602 - declare the local journal protocol stable in the wiki interface chart
603 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
604 - journald: when dropping msgs due to ratelimit make sure to write
605 "dropped %u messages" not only when we are about to print the next
606 message that works, but alraedy after a short tiemout
607 - check if we can make journalctl by default use --follow mode inside of less if called without args?
608 - maybe add API to send pairs of iovecs via sd_journal_send
609 - journal: when writing journal auto-rotate if time jumps backwards
610 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
611 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
612 and !FOOBAR for events without FOOBAR.
613 - journal: store timestamp of journal_file_set_offline() int he header,
614 so it is possible to display when the file was last synced.
615 - 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.
616 - journal: find a way to allow dropping history early, based on priority, other rules
617 - journal: When used on NFS, check payload hashes
618 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
619 - refuse taking lower-case variable names in sd_journal_send() and friends.
620 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
621 - journal: deal nicely with byte-by-byte copied files, especially regards header
622 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
623 - Replace utmp, wtmp, btmp, and lastlog completely with journal
624 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
625 - when a kernel driver logs in a tight loop, we should ratelimit that too.
626 - journald: optionally, log debug messages to /run but everything else to /var
627 - journald: when we drop syslog messages because the syslog socket is
628 full, make sure to write how many messages are lost as first thing
629 to syslog when it works again.
630 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
631 - change systemd-journal-flush into a service that stays around during
632 boot, and causes the journal to be moved back to /run on shutdown,
633 so that we do not keep /var busy. This needs to happen synchronously,
634 hence doing this via signals is not going to work.
635 - optionally support running journald from the command line for testing purposes in external projects
636 - journald: allow per-priority and per-service retention times when rotating/vacuuming
637 - journald: make use of uid-range.h to managed uid ranges to split
639 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
640 - improve journalctl performance by loading journal files
641 lazily. Encode just enough information in the file name, so that we
642 do not have to open it to know that it is not interesting for us, for
643 the most common operations.
646 - document that deps in [Unit] sections ignore Alias= fields in
647 [Install] units of other units, unless those units are disabled
648 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
649 - document the exit codes when services fail before they are exec()ed
650 - document that service reload may be implemented as service reexec
651 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
652 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
653 - document systemd-journal-flush.service properly
654 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
655 - man: document the very specific env the shutdown drop-in tools live in
656 - man: add more examples to man pages
657 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
660 - systemctl list-jobs - show dependencies
661 - add systemctl switch to dump transaction without executing it
662 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
663 - "systemctl disable" on a static unit prints no message and does
664 nothing. "systemctl enable" does nothing, and gives a bad message
665 about it. Should fix both to print nice actionable messages.
666 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
667 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
668 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
669 - systemctl: "Journal has been rotated since unit was started." message is misleading
670 - better error message if you run systemctl without systemd running
671 - systemctl status output should should include list of triggering units and their status
674 - "systemctl mask" should find all names by which a unit is accessible
675 (i.e. by scanning for symlinks to it) and link them all to /dev/null
676 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
679 - timer units should get the ability to trigger when:
680 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
682 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
683 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
684 - Modulate timer frequency based on battery state
686 * add libsystemd-password or so to query passwords during boot using the password agent logic
688 * 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().
690 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
692 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
694 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
695 waiting for the timeout
697 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
699 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
702 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
705 - cryptsetup-generator: allow specification of passwords in crypttab itself
706 - move cryptsetup key caching into kernel keyctl?
707 https://bugs.freedesktop.org/show_bug.cgi?id=54982
708 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
710 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
711 https://bugs.freedesktop.org/show_bug.cgi?id=54712
713 * after deserializing sockets in socket.c we should reapply sockopts and things
715 * make timer units go away after they elapsed
717 * move PID 1 segfaults to /var/lib/systemd/coredump?
719 * create /sbin/init symlinks from the build system
721 * allow writing multiple conditions in unit files on one line
723 * MountFlags=shared acts as MountFlags=slave right now.
725 * drop PID 1 reloading, only do reexecing (difficult: Reload()
726 currently is properly synchronous, Reexec() is weird, because we
727 cannot delay the response properly until we are back, so instead of
728 being properly synchronous we just keep open the fd and close it
729 when done. That means clients do not get a successful method reply,
730 but much rather a disconnect on success.
732 * properly handle loop back mounts via fstab, especially regards to fsck/passno
734 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
736 * rename "userspace" to "core-os"
738 * load-fragment: when loading a unit file via a chain of symlinks
739 verify that it is not masked via any of the names traversed.
741 * introduce Type=pid-file
743 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
745 * ExecOnFailure=/usr/bin/foo
750 - add trigger --subsystem-match=usb/usb_device device
751 - reimport udev db after MOVE events for devices without dev_t
753 * when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
755 * introduce mix of BindTo and Requisite
757 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
759 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
761 * save coredump in Windows/Mozilla minidump format
763 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
765 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
767 * be able to specify a forced restart of service A where service B depends on, in case B
768 needs to be auto-respawned?
770 * when a bus name of a service disappears from the bus make sure to queue further activation requests
773 - apply "x" on "D" too (see patch from William Douglas)
775 - instead of ignoring unknown fields, reject them.
777 * for services: do not set $HOME in services unless requested
779 * hide PAM options in fragment parser when compile time disabled
781 * when we automatically restart a service, ensure we restart its rdeps, too.
783 * allow Type=simple with PIDFile=
784 https://bugzilla.redhat.com/show_bug.cgi?id=723942
786 * move PAM code into its own binary
788 * implement Register= switch in .socket units to enable registration
789 in Avahi, RPC and other socket registration services.
791 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
793 * add ReloadSignal= for configuring a reload signal to use
795 * verify that the AF_UNIX sockets of a service in the fs still exist
796 when we start a service in order to avoid confusion when a user
797 assumes starting a service is enough to make it accessible
799 * Make it possible to set the keymap independently from the font on
800 the kernel cmdline. Right now setting one resets also the other.
802 * and a dbus call to generate target from current state
804 * GC unreferenced jobs (such as .device jobs)
806 * write blog stories about:
807 - hwdb: what belongs into it, lsusb
808 - enabling dbus services
810 - how to make changes to sysctl and sysfs attributes

823 - instantiated apache, dovecot and so on
824 - hooking a script into various stages of shutdown/rearly booot
826 * allow port=0 in .socket units
828 * recreate systemd's D-Bus private socket file on SIGUSR2
830 * Support --test based on current system state
832 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
834 * maybe introduce ExecRestartPre=
836 * dot output for --test showing the 'initial transaction'
838 * fingerprint.target, wireless.target, gps.target, netdevice.target
841 - figure out a simple way to wait for journal events in a way that
843 - add documentation to systemd.daemon
846 - plot per-process IO utilization
847 - group processes based on service association (cgroups)
848 - document initcall_debug
849 - kernel cmdline "bootchart" option for simplicity?
852 - Make sure ID_PATH is always exported and complete for
853 network devices where possible, so we can safely rely
855 - check MTUBytes parsing (expecting size_t but we are using unsigned)
858 - add support for more attribute types
859 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
862 - add more keys to [Route] and [Address] sections
863 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
864 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
865 - add reduced [Link] support to .network files
866 - add Scope= parsing option for [Network]
867 - properly handle routerless dhcp leases
868 - add more attribute support for SIT tunnel
869 - work with non-Ethernet devices
870 - add support for more bond options
872 * networkd-wait-online:
873 - make operstates to wait for configurable?
876 - figure out how much we can increase Maximum Message Size
877 - support RFC4702 (pass FQDN)
880 - add functions to set previously stored IPv6 addresses on startup and get
881 them at shutdown; store them in client->ia_na
882 - write more test cases
883 - implement reconfigure support, see 5.3., 15.11. and 22.20.
884 - implement support for temporary adressess (IA_TA)
885 - implement dhcpv6 authentication
886 - investigate the usefulness of Confirm messages; i.e. are there any
887 situations where the link changes without any loss in carrier detection
889 - some servers don't do rapid commit without a filled in IA_NA, verify
895 - natively watch for dbus-*.service symlinks (PENDING)
896 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
898 * fix alsa mixer restore to not print error when no config is stored
900 * make cryptsetup lower --iter-time
902 * patch kernel for xattr support in /dev, /proc/, /sys?
904 * kernel: add device_type = "fb", "fbcon" to class "graphics"
906 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
908 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
910 * /usr/bin/service should actually show the new command line
912 * 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=
914 * fedora: F20: go timer units all the way, leave cron.daily for cron
916 * neither pkexec nor sudo initialize environ[] from the PAM environment?
918 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
920 * register catalog database signature as file magic
922 * zsh shell completion:
923 - <command> <verb> -<TAB> should complete options, but currently does not
924 - systemctl add-wants,add-requires
929 * look for close() vs. close_nointr() vs. close_nointr_nofail()
931 * check for strerror(r) instead of strerror(-r)
933 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
937 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
939 * use secure_getenv() instead of getenv() where appropriate
941 * link up selected blog stories from man pages and unit files Documentation= fields
