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
24 * When lz4 gets an API for lz4 command output, make use of it to
25 compress coredumps in a way compatible with /usr/bin/lz4.
29 * add a concept of RemainAfterExit= to scope units
31 * add journal vacuum by max number of files
33 * add a new command "systemctl revert" or so, that removes all dropin
34 snippets in /run and /etc, and all unit files with counterparts in
35 /usr, and thus undoes what "systemctl set-property" and "systemctl
36 edit" create. Maybe even add "systemctl revert -a" to do this for
39 * sd-event: maybe add support for inotify events
41 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
43 * nspawn should send out sd_notify("WATCHDOG=1") messages
45 * nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
47 * consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
49 * "systemctl edit" should know a mode to create a new unit file
51 * there's probably something wrong with having user mounts below /sys,
52 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
53 prefixed with /sys generally special.
54 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
56 * Add PassEnvironment= setting to service units, to import select env vars from PID 1 into the service env block
58 * nspawn: fix logic always print a final newline on output.
59 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
61 * make nspawn's --network-veth switch more powerful:
62 http://lists.freedesktop.org/archives/systemd-devel/2015-June/033121.html
64 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
66 * man: clarify that "machinectl show" shows different information than "machinectl status" (no cgroup tree, no IP addresses, ...)
68 * "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
70 * install: include generator dirs in unit file search paths
72 * logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
74 * invent a better systemd-run scheme for naming scopes, that works with remoting
76 * add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
78 * change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
80 * add a version of --merge which also merges /var/log/journal/remote
82 * log accumulated resource usage after each service invocation
84 * 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
86 * logind: rename session scope so that it includes the UID. THat way
87 the session scope can be arranged freely in slices and we don't have
88 make assumptions about their slice anymore.
90 * 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.
92 * nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
94 * nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
96 * importd: generate a nice warning if mkfs.btrfs is missing
98 * 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
100 * nspawn: Improve error message when --bind= is used on a non-existing source directory
102 * nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
104 * man: document how update dkr images works with machinectl
105 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
107 * 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
109 * rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
110 to unicode chars, to make things more expressive.
112 * "machinectl migrate" or similar to copy a container from or to a
113 difference host, via ssh
115 * tmpfiles: creating new directories/subvolumes/fifos/device nodes
116 should not follow symlinks. None of the other adjustment or creation
117 calls follow symlinks.
119 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
121 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
123 * mounting and unmounting mount points manually with different source
124 devices will result in collected collected on all devices used.
125 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
127 * add a job mode that will fail if a transaction would mean stopping
128 running units. Use this in timedated to manage the NTP service
130 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
132 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
133 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
135 * .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
137 * create a btrfs qgroup for /var/lib/machines, and add all container
138 subvolumes we create to it.
140 * When logging about multiple units (stopping BoundTo units, conflicts, etc.),
141 log both units as UNIT=, so that journalctl -u triggers on both.
143 * to allow "linking" of nspawn containers, extend --network-bridge= so
144 that it can dynamically create bridge interfaces that are refcounted
145 by the containers on them. For each group of containers to link together
147 * journalctl --verify: don't show files that are currently being
148 written to as FAIL, but instead show that their are being written
151 * assign MESSAGE_ID to log messages about failed services
153 * coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
154 and supress coredump if turned off. Then change RLIMIT_CORE to
155 infinity by default for all services. This then allows per-service
156 control of coredumping.
158 * generate better errors when people try to set transient properties
159 that are not supported...
160 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
162 * Introduce $LISTEN_NAMES to complement $LISTEN_FDS, containing a
163 colon separated list of identifiers for the fds passed.
165 * maybe introduce WantsMountsFor=? Usecase:
166 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
168 * rework kexec logic to use new kexec_file_load() syscall, so that we
169 don't have to call kexec tool anymore.
171 * The udev blkid built-in should expose a property that reflects
172 whether media was sensed in USB CF/SD card readers. This should then
173 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
174 picked up by systemd unless they contain a medium. This would mirror
175 the behaviour we already have for CD drives.
177 * nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
178 with seccomp. That should provide us with a useful log buffer that
179 systemd can log to during early boot, and disconnect container logs
180 from the kernel's logs.
182 * networkd/udev: implement SR_IOV configuration in .link files:
183 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
185 * When RLIMIT_NPROC is set from a unit file it currently always is set
186 for root, not for the user set in User=, which makes it
187 useless. After fixing this, set RLIMIT_NPROC for
188 systemd-journal-xyz, and all other of our services that run under
189 their own user ids, and use User= (but only in a world where userns
190 is ubiquitous since otherwise we cannot invoke those daemons on the
191 host AND in a container anymore). Also, if LimitNPROC= is used
192 without User= we should warn and refuse operation.
194 * logind: maybe allow configuration of the StopTimeout for session scopes
196 * Set NoNewPrivileges= on all of our own services, where that makes sense
198 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
200 * rework journald sigbus stuff to use mutex
202 * import-dkr: support tarsum checksum verification, if it becomes reality one day...
204 * import-dkr: convert json bits to nspawn configuration
206 * 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
208 * introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
210 * "machinectl status" should also show internal logs of the container in question
212 * "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
214 * Port various tools to make use of verbs.[ch], where applicable
216 * "machinectl history"
220 * "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
222 * systemd-nspawn -x should support ephemeral instances of gpt images
224 * hostnamectl: show root image uuid
226 * sysfs set api in libudev is not const
228 * Find a solution for SMACK capabilities stuff:
229 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
231 * port libmount hookup to use API's own inotify interface, as soon as that is table in libmount
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 * code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
276 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
278 * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
280 * consider showing the unit names during boot up in the status output, not just the unit descriptions
282 * dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
284 * maybe allow timer units with an empty Units= setting, so that they
285 can be used for resuming the system but nothing else.
287 * what to do about udev db binary stability for apps? (raw access is not an option)
289 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
291 * maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
293 * man: document that corrupted journal files is nothing to act on
295 * man: maybe use the word "inspect" rather than "introspect"?
297 * "machinectl list" should probably show columns for OS version and IP addresses
299 * systemctl: if some operation fails, show log output?
302 - allow creation of units from scratch
303 - use equvalent of cat() to insert existing config as a comment, prepended with #.
304 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
306 * refcounting in sd-resolve is borked
308 * exponential backoff in timesyncd and resolved when we cannot reach a server
310 * extract_many_words() should probably be used by a lot of code that
311 currently uses FOREACH_WORD and friends. For example, most conf
312 parsing callbacks should use it.
314 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
316 * systemd.show_status= should probably have a mode where only failed
319 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
320 (throughout the codebase, not only PID1)
323 - add LLDP client side support
324 - the DHCP lease data (such as NTP/DNS) is still made available when
325 a carrier is lost on a link. It should be removed instantly.
326 - expose in the API the following bits:
327 - option 15, domain name and/or option 119, search list
328 - option 12, host name and/or option 81, fqdn
329 - option 123, 144, geolocation
330 - option 252, configure http proxy (PAC/wpad)
331 - provide a way to define a per-network interface default metric value
332 for all routes to it. possibly a second default for DHCP routes.
333 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
334 support Name=foo*|bar*|baz ?
335 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
336 - allow DUID/IAID to be customized, see issue #394.
337 - support configuration option for TSO (tcp segmentation offload)
338 - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW
341 - put networkd events and rtnl events at a higher priority, so that
342 we always process them before we process client requests
344 - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
349 - DNS-SD service registration from socket units
351 - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
352 announce dname support. However, for DNSSEC it is necessary as the synthesized cname
356 * Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
358 * Add a new verb "systemctl top"
360 * add new gpt type for btrfs volumes
362 * support empty /etc boots nicely:
363 - nspawn/gpt-generator: introduce new gpt partition type for /usr
364 - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
366 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
368 * timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
370 * a way for container managers to turn off getty starting via $container_headless= or so...
372 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
374 * mount_cgroup_controllers(): symlinks need to get the label applied
376 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
377 they run added to the initial transaction and thus confuse Type=idle.
379 * 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)
381 * sd-event: generate a failure of a default event loop is executed out-of-thread
383 * add bus api to query unit file's X fields.
385 * consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
387 * sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
389 * gpt-auto-generator:
390 - Support LUKS for root devices
391 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
392 - Make /home automount rather than mount?
394 * add generator that pulls in systemd-network from containers when
395 CAP_NET_ADMIN is set, more than the loopback device is defined, even
396 when it is otherwise off
398 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
400 * "busctl status" works only as root on dbus1, since we cannot read
403 * implement Distribute= in socket units to allow running multiple
404 service instances processing the listening socket, and open this up
407 * socket units: support creating sockets in different namespace,
408 opening it up for JoinsNamespaceOf=. This would require to fork off
409 a tiny process that joins the namespace and creates/binds the socket
410 and passes this back to PID1 via SCM_RIGHTS. This also could be used
411 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
413 * New service property: maximum CPU and wallclock runtime for a service
415 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
416 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
417 should SIGSTOP all unit processes in a loop until all processes of
418 it are fully stopped. This can later be used for app management by
419 desktop UIs such as gnome-shell to freeze apps that are not visible
420 on screen, not unlike how job control works on the shell
423 - implement per-slice CPUFairScheduling=1 switch
424 - handle jointly mounted controllers correctly
425 - introduce high-level settings for RT budget, swappiness
426 - how to reset dynamically changed unit cgroup attributes sanely?
427 - when reloading configuration, apply new cgroup configuration
428 - when recursively showing the cgroup hierarchy, optionally also show
429 the hierarchies of child processes
432 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
433 - ensure scope units may be started only a single time
435 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
437 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
439 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
441 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
443 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
445 * unify dispatch table in systemctl_main() and friends
447 * 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
449 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
451 * If we try to find a unit via a dangling symlink, generate a clean
452 error. Currently, we just ignore it and read the unit from the search
455 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
457 * btrfs raid assembly: some .device jobs stay stuck in the queue
459 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
461 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
463 * load .d/*.conf dropins for device units
465 * allow implementation of InaccessibleDirectories=/ plus
466 ReadOnlyDirectories=... for whitelisting files for a service.
470 - GetAllProperties() on a non-existing object does not result in a failure currently
471 - kdbus: process fd=-1 for incoming msgs
472 - port to sd-resolve for connecting to TCP dbus servers
473 - kdbus: maybe add controlling tty metadata fields
474 - 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
475 - when kdbus does not take our message without memfds, try again with memfds
476 - see if we can drop more message validation on the sending side
477 - add API to clone sd_bus_message objects
478 - make AddMatch calls on dbus1 transports async?
479 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
480 - longer term: priority inheritance
483 - NameLost/NameAcquired obsolete
486 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
487 - test bloom filter generation indexes
488 - bus-proxy: when passing messages from kdbus, make sure we properly
489 handle the case where a large number of fds is appended that we
490 cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
492 - kdbus: introduce a concept of "send-only" connections
493 - 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.
496 - allow multiple signal handlers per signal?
497 - document chaining of signal handler for SIGCHLD and child handlers
499 * in the final killing spree, detect processes from the root directory, and
500 complain loudly if they have argv[0][0] == '@' set.
501 https://bugzilla.redhat.com/show_bug.cgi?id=961044
503 * investigate endianness issues of UUID vs. GUID
505 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
506 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
508 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
510 * add a pam module that on password changes updates any LUKS slot where the password matches
512 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
514 * cgtop: make cgtop useful in a container
517 - add 'set -e' to scripts in test/
518 - make stuff in test/ work with separate output dir
520 * seems that when we follow symlinks to units we prefer the symlink
521 destination path over /etc and /usr. We should not do that. Instead
522 /etc should always override /run+/usr and also any symlink
525 * when isolating, try to figure out a way how we implicitly can order
526 all units we stop before the isolating unit...
528 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
530 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
531 that the boot loader should be installed to the ESP. Define a way
532 how an installer can figure out whether a BLS compliant boot loader
535 * think about requeuing jobs when daemon-reload is issued? usecase:
536 the initrd issues a reload after fstab from the host is accessible
537 and we might want to requeue the mounts local-fs acquired through
540 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
542 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
544 * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
546 * shutdown logging: store to EFI var, and store to USB stick?
548 * write UI tool that pops up emergency messages from the journal as notification
550 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
552 * merge unit_kill_common() and unit_kill_context()
554 * introduce ExecCondition= in services
557 - honor language efi variables for default language selection (if there are any?)
558 - honor timezone efi variables for default timezone selection (if there are any?)
559 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
561 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
563 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
564 https://bugzilla.redhat.com/show_bug.cgi?id=812826
566 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
568 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
571 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
572 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
573 - logind: wakelock/opportunistic suspend support
574 - Add pretty name for seats in logind
575 - logind: allow showing logout dialog from system?
576 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
577 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
578 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
579 - if pam_systemd is invoked by su from a process that is outside of a
580 any session we should probably just become a NOP, since that's
581 usually not a real user session but just some system code that just
583 - logind: make the Suspend()/Hibernate() bus calls wait for the for
584 the job to be completed. before returning, so that clients can wait
585 for "systemctl suspend" to finish to know when the suspending is
587 - logind: when the power button is pressed short, just popup a
588 logout dialog. If it is pressed for 1s, do the usual
589 shutdown. Inspiration are Macs here.
590 - expose "Locked" property on logind sesison objects
591 - given that logind now lets PID 1 do all nasty work, we can
592 probably reduce the capability set it retains substantially.
593 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
594 - expose orientation sensors and tablet mode through logind
596 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
598 * service: watchdog logic: for testing purposes allow ping, but do not require pong
601 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
602 - import and delete pstore filesystem content at startup
603 - journald: also get thread ID from client, plus thread name
604 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
605 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
606 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
607 - declare the local journal protocol stable in the wiki interface chart
608 - journal: reuse XZ context
609 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
610 - journald: when dropping msgs due to ratelimit make sure to write
611 "dropped %u messages" not only when we are about to print the next
612 message that works, but alraedy after a short tiemout
613 - check if we can make journalctl by default use --follow mode inside of less if called without args?
614 - maybe add API to send pairs of iovecs via sd_journal_send
615 - journal: when writing journal auto-rotate if time jumps backwards
616 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
617 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
618 and !FOOBAR for events without FOOBAR.
619 - journal: store timestamp of journal_file_set_offline() int he header,
620 so it is possible to display when the file was last synced.
621 - 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.
622 - journal: find a way to allow dropping history early, based on priority, other rules
623 - journal: When used on NFS, check payload hashes
624 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
625 - refuse taking lower-case variable names in sd_journal_send() and friends.
626 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
627 - journal: deal nicely with byte-by-byte copied files, especially regards header
628 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
629 - Replace utmp, wtmp, btmp, and lastlog completely with journal
630 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
631 - when a kernel driver logs in a tight loop, we should ratelimit that too.
632 - journald: optionally, log debug messages to /run but everything else to /var
633 - journald: when we drop syslog messages because the syslog socket is
634 full, make sure to write how many messages are lost as first thing
635 to syslog when it works again.
636 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
637 - change systemd-journal-flush into a service that stays around during
638 boot, and causes the journal to be moved back to /run on shutdown,
639 so that we do not keep /var busy. This needs to happen synchronously,
640 hence doing this via signals is not going to work.
641 - optionally support running journald from the command line for testing purposes in external projects
642 - journald: allow per-priority and per-service retention times when rotating/vacuuming
643 - journald: make use of uid-range.h to managed uid ranges to split
645 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
646 - improve journalctl performance by loading journal files
647 lazily. Encode just enough information in the file name, so that we
648 do not have to open it to know that it is not interesting for us, for
649 the most common operations.
652 - document that deps in [Unit] sections ignore Alias= fields in
653 [Install] units of other units, unless those units are disabled
654 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
655 - document the exit codes when services fail before they are exec()ed
656 - document that service reload may be implemented as service reexec
657 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
658 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
659 - document systemd-journal-flush.service properly
660 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
661 - man: document the very specific env the shutdown drop-in tools live in
662 - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
663 - man: add more examples to man pages
664 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
667 - systemctl list-jobs - show dependencies
668 - add systemctl switch to dump transaction without executing it
669 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
670 - "systemctl disable" on a static unit prints no message and does
671 nothing. "systemctl enable" does nothing, and gives a bad message
672 about it. Should fix both to print nice actionable messages.
673 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
674 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
675 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
676 - systemctl: "Journal has been rotated since unit was started." message is misleading
677 - support "systemctl stop foobar@.service" to stop all units matching a certain template
678 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
679 - better error message if you run systemctl without systemd running
680 - systemctl status output should should include list of triggering units and their status
683 - "systemctl mask" should find all names by which a unit is accessible
684 (i.e. by scanning for symlinks to it) and link them all to /dev/null
685 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
688 - timer units should get the ability to trigger when:
689 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
691 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
692 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
693 - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
694 - Modulate timer frequency based on battery state
696 * add libsystemd-password or so to query passwords during boot using the password agent logic
698 * 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().
700 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
702 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
704 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
705 waiting for the timeout
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 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
715 - cryptsetup-generator: allow specification of passwords in crypttab itself
716 - move cryptsetup key caching into kernel keyctl?
717 https://bugs.freedesktop.org/show_bug.cgi?id=54982
718 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
720 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
721 https://bugs.freedesktop.org/show_bug.cgi?id=54712
723 * after deserializing sockets in socket.c we should reapply sockopts and things
725 * make timer units go away after they elapsed
727 * move PID 1 segfaults to /var/lib/systemd/coredump?
729 * create /sbin/init symlinks from the build system
731 * allow writing multiple conditions in unit files on one line
733 * MountFlags=shared acts as MountFlags=slave right now.
735 * drop PID 1 reloading, only do reexecing (difficult: Reload()
736 currently is properly synchronous, Reexec() is weird, because we
737 cannot delay the response properly until we are back, so instead of
738 being properly synchronous we just keep open the fd and close it
739 when done. That means clients do not get a successful method reply,
740 but much rather a disconnect on success.
742 * properly handle loop back mounts via fstab, especially regards to fsck/passno
744 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
746 * rename "userspace" to "core-os"
748 * load-fragment: when loading a unit file via a chain of symlinks
749 verify that it is not masked via any of the names traversed.
751 * introduce Type=pid-file
753 * change Requires=basic.target to RequisiteOverride=basic.target
755 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
757 * ExecOnFailure=/usr/bin/foo
762 - add trigger --subsystem-match=usb/usb_device device
763 - reimport udev db after MOVE events for devices without dev_t
765 * 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
767 * introduce mix of BindTo and Requisite
769 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
771 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
773 * default unix qlen is too small (10). bump sysctl? add sockopt?
775 * save coredump in Windows/Mozilla minidump format
777 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
779 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
781 * be able to specify a forced restart of service A where service B depends on, in case B
782 needs to be auto-respawned?
784 * when a bus name of a service disappears from the bus make sure to queue further activation requests
787 - apply "x" on "D" too (see patch from William Douglas)
789 - instead of ignoring unknown fields, reject them.
791 * for services: do not set $HOME in services unless requested
793 * hide PAM options in fragment parser when compile time disabled
795 * when we automatically restart a service, ensure we restart its rdeps, too.
797 * allow Type=simple with PIDFile=
798 https://bugzilla.redhat.com/show_bug.cgi?id=723942
800 * move PAM code into its own binary
802 * implement Register= switch in .socket units to enable registration
803 in Avahi, RPC and other socket registration services.
805 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
807 * add ReloadSignal= for configuring a reload signal to use
809 * verify that the AF_UNIX sockets of a service in the fs still exist
810 when we start a service in order to avoid confusion when a user
811 assumes starting a service is enough to make it accessible
813 * Make it possible to set the keymap independently from the font on
814 the kernel cmdline. Right now setting one resets also the other.
816 * and a dbus call to generate target from current state
818 * GC unreferenced jobs (such as .device jobs)
820 * write blog stories about:
821 - hwdb: what belongs into it, lsusb

838 - hooking a script into various stages of shutdown/rearly booot
840 * allow port=0 in .socket units
842 * recreate systemd's D-Bus private socket file on SIGUSR2
844 * Support --test based on current system state
846 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
848 * maybe introduce ExecRestartPre=
850 * dot output for --test showing the 'initial transaction'
852 * fingerprint.target, wireless.target, gps.target, netdevice.target
855 - figure out a simple way to wait for journal events in a way that
857 - add documentation to systemd.daemon
860 - plot per-process IO utilization
861 - group processes based on service association (cgroups)
862 - document initcall_debug
863 - kernel cmdline "bootchart" option for simplicity?
866 - Make sure ID_PATH is always exported and complete for
867 network devices where possible, so we can safely rely
869 - check MTUBytes parsing (expecting size_t but we are using unsigned)
872 - add support for more attribute types
873 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
876 - add more keys to [Route] and [Address] sections
877 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
878 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
879 - add reduced [Link] support to .network files
880 - add Scope= parsing option for [Network]
881 - properly handle routerless dhcp leases
882 - add more attribute support for SIT tunnel

887 - make operstates to wait for configurable?
890 - figure out how much we can increase Maximum Message Size
891 - support RFC4702 (pass FQDN)
894 - add functions to set previously stored IPv6 addresses on startup and get
895 them at shutdown; store them in client->ia_na
896 - write more test cases
897 - implement reconfigure support, see 5.3., 15.11. and 22.20.
898 - implement support for temporary adressess (IA_TA)
899 - implement dhcpv6 authentication
900 - investigate the usefulness of Confirm messages; i.e. are there any
901 situations where the link changes without any loss in carrier detection
903 - some servers don't do rapid commit without a filled in IA_NA, verify
909 - natively watch for dbus-*.service symlinks (PENDING)
910 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
912 * fix alsa mixer restore to not print error when no config is stored
914 * make cryptsetup lower --iter-time
916 * patch kernel for xattr support in /dev, /proc/, /sys?
918 * kernel: add device_type = "fb", "fbcon" to class "graphics"
920 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
922 * dbus upstream still refers to dbus.target and should not
924 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
926 * add "# export SYSTEMD_PAGER=" to bash login
928 * /usr/bin/service should actually show the new command line
930 * 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=
932 * fedora: F20: go timer units all the way, leave cron.daily for cron
934 * neither pkexec nor sudo initialize environ[] from the PAM environment?
936 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
938 * register catalog database signature as file magic
940 * zsh shell completion:
941 - <command> <verb> -<TAB> should complete options, but currently does not
942 - systemctl add-wants,add-requires
947 * look for close() vs. close_nointr() vs. close_nointr_nofail()
949 * check for strerror(r) instead of strerror(-r)
951 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
955 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
957 * use secure_getenv() instead of getenv() where appropriate
959 * link up selected blog stories from man pages and unit files Documentation= fields
961 Scheduled for removal or fixing:
963 * xxxOverridable dependencies (probably: fix)
