3 * Many manager configuration settings that are only applicable to user
4 manager or system manager can be always set. It would be better to reject
5 them when parsing config.
7 * busctl prints errors to stdout:
8 busctl tree org.freedesktop.systemd1 /org/freedesktop/systemd1
12 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
14 * wiki: update journal format documentation for lz4 additions
18 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
20 * rework mount.c and swap.c to follow proper state enumeration/deserialization
21 semantics, like we do for device.c now
25 * machined: add API to acquire UID range. add API to mount/dissect loopback
26 file. Both protected by PK. Then make nspawn use these APIs to run
27 unprivileged containers. i.e. push the truly privileged bits into machined,
28 so that the client side can remain entirely unprivileged, with SUID or
31 * add "throttling" to sd-event event sources: optionally, when we wake up too
32 often for one, let's turn it off entirely for a while. Use that for the
33 /proc/self/mountinfo logic.
35 * move our systemd-user PAM snippet to /usr/, which PAM appears to support
38 * nspawn: support time namespaces
40 * pid1: Move to tracking of main pid/control pid of units per pidfd
42 * pid1: support new clone3() fork-into-cgroup feature
44 * pid1: also remove PID files of a service when the service starts, not just
47 * make "systemd-dissect" an official supported tool, i.e. move to /usr/bin/ and
48 provide man page. Given that we now have a tool that can generate images like
49 this, it's useful to have one that can dump contents of them, too.
51 * All tools that support --root= should also learn --image= so that they can
52 operate on disk images directly. Specifically: bootctl, firstboot, tmpfiles,
53 sysusers, systemctl, repart, journalctl, coredumpctl.
55 * per-service credential system. Specifically: add LoadCredential= (for loading
56 cred from file), AcquireCredential= (for asking user for cred, via
57 ask-password), PassCredential= (for passing on credential systemd itself
58 got). Then, place credentials in a per-service, immutable ramfs instance (so
59 that it cannot be swapped out), destroy after use. Also pass via keyring
60 (with graceful fallback to cover for containers). Define CredentialPath= for
61 defining subdir of /run/credentials/ where to place it. Set $CREDENTIAL_PATH
62 env var for services to the result. Also pass via fd passing (optionally).
64 * homed: add native recovery key support. use 48 lowercase modhex characters
65 (192bit), show qr code of it, include pattern expression in user record.
67 * homed: introduce "degraded" state for home directories that weren't cleanly
68 unmounted (use xattr we add and remove on the loop back file)
70 * homed: during login resize fs automatically towards size goal. Specifically,
71 resize to diskSize if possible, but leave a certain amount (configured by a
72 new value diskLeaveFreeSize) of space free on the backing fs.
74 * homed: permit multiple user record signing keys to be used locally, and pick
75 the right one for signing records automatically depending on a pre-existing
78 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
79 and insert a local signature instead.
81 * homed: as an extension to the directory+subvolume backend: if located on
82 especially marked fs, then sync down password into LUKS header of that fs,
83 and always verify passwords against it too. Bootstrapping is a problem
84 though: if noone is logged in (or no other user even exists yet), how do you
85 unlock the volume in order to create the first user and add the first pw.
87 * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
89 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
92 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
95 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
96 root partitions, do an strverscmp() on the partition label and boot
97 first. That is inspired how sd-boot figures out which kernel to boot, and
98 thus allows defining OS images which can be A/B updated and we default to the
99 newest version automatically, both in nspawn and in sd-boot
101 * cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
102 devices. (see: https://github.com/mjec/fido2-hmac-secret)
104 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
107 * homed/userdb: distinguish passwords and recovery keys in the records, since
108 we probably want to use different PBKDF algorithms/settings for them:
109 passwords have low entropy but recovery keys should have good entropy key
110 hence we can make them quicker to work.
113 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
114 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
115 - make it operate on loopback files, dissecting enough to find ESP to operate on
117 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
118 allow so that systemd survives
120 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
121 "base64:" prefix. Useful in particular for pkcs11 mode.
123 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
124 systemd-makefs.service instead.
126 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
127 with matches, then activate app through that passing socket over
130 - port sd_id128_get_machine_app_specific() over from khash
131 - port resolved over from libgcrypt (DNSSEC code)
132 - port journald + fsprg over from libgcrypt
133 - port importd over from libgcrypt
134 - when that's done: kill khash.c
135 - when that's done: kill gnutls support in resolved
137 * kill zenata, all hail weblate?
139 * when we resize disks (homed?) always round up to 4K sectors, not 512K
141 * add growvol and makevol options for /etc/crypttab, similar to
142 x-systemd.growfs and x-systemd-makefs.
144 * hook up the TPM to /etc/crypttab, with a new option that is similar to the
145 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
146 unsealed from the TPM. Optionally, if TPM is not available fall back to
147 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
148 that the device paths stay the same, regardless if crypto is used or not.
150 * systemd-repart: by default generate minimized partition tables (i.e. tables
151 that only cover the space actually used, excluding any free space at the
152 end), in order to maximize dd'ability. Requires libfdisk work, see
153 https://github.com/karelzak/util-linux/issues/907
155 * systemd-repart: optionally, allow specifying a path to initialize new
156 partitions from, i.e. an fs image file or a source device node. This would
157 then turn systemd-repart into a simple installer: with a few .repart files
158 you could replicate the host system on another device. a full installer would
159 then be: "systemd-repart /dev/sda && bootctl install /dev/sda &&
160 systemd-firstboot --image= …"
162 * systemd-repart: MBR partition table support. Care needs to be taken regarding
163 Type=, so that partition definitions can sanely apply to both the GPT and the
164 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
165 for the two partition types explicitly. And provide an internal mapping so
166 that "Type=linux-generic" maps to the right types for both partition tables
169 * systemd-repart: allow sizing partitions as factor of available RAM, so that
170 we can reasonably size swap partitions for hibernation.
172 * systemd-repart: allow running mkfs before making partitions pop up +
173 encryption via LUKS to allow booting into an empty root with only /usr mounted in
175 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
177 * systemd-repart: allow disabling growing of specific partitions, or making
178 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
180 * systemd-repart: add specifier expansion, add especifier that refers to root
181 device node of current system, /usr device node, and matching verity, so that
182 an installer can be made a "copy" installer of the booted OS
184 * systemd-repart: make it a static checker during early boot for existence and
185 absence of other partitions for trusted boot environments
187 * systemd-repart: allow config of partition uuid
189 * userdb: allow username prefix searches in varlink API, allow realname and
190 realname substr searches in varlink API
192 * userdb: allow uid/gid range checks
194 * userdb: allow existence checks
196 * pid1: activation by journal search expression
198 * when switching root from initrd to host, set the machine_id env var so that
199 if the host has no machine ID set yet we continue to use the random one the
202 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
203 it fo reaping assigned but unknown children. This needs to some special care
204 to operate somewhat sensibly in light of priorities: P_ALL will return
205 arbitrary processes, regardless of the priority we want to watch them with,
206 hence on each event loop iteration check all processes which we shall watch
207 with higher prio explicitly, and then watch the entire rest with P_ALL.
209 * tweak sd-event's child watching: keep a prioq of children to watch and use
210 waitid() only on the children with the highest priority until one is waitable
211 and ignore all lower-prio ones from that point on
213 * maybe introduce xattrs that can be set on the root dir of the root fs
214 partition that declare the volatility mode to use the image in. Previously I
215 thought marking this via GPT partition flags but that's not ideal since
216 that's outside of the LUKS encryption/verity verification, and we probably
217 shouldn't operate in a volatile mode unless we got told so from a trusted
220 * figure out automatic partition discovery when combining writable root dir
223 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
224 may be used to mark a whole binary as non-coredumpable. Would fix:
225 https://bugs.freedesktop.org/show_bug.cgi?id=69447
227 * teach parse_timestamp() timezones like the calendar spec already knows it
229 * beef up hibernation to optionally do swapon/swapoff immediately before/after
232 * beef up s2h to implement a battery watch loop: instead of entering
233 hibernation unconditionally after coming back from resume make a decision
234 based on the battery load level: if battery level is above a specific
235 threshold, go to suspend again, only hibernate if below it. This means we'd
236 stick to suspend usually, but fall back to hibernation only when battery runs
237 empty (well, subject to our sampling interval). Related to this, check if we
238 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
239 i.e. see if it can wake up machines from suspend, so that we could resume
240 automatically when the system is low on power and move automatically to
241 hibernation mode. (see
242 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
244 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
247 * add an explicit "vertical" mode to format-table, so that "systemctl
248 status"-like outputs (i.e. with a series of field names left and values
249 right) become genuine first class citizens, and we gain automatic, sane JSON
252 * systemd-firstboot: teach it dissector magic, so that you can point it to some
253 disk image and it will just set everything in it all behind the scenes.
255 * systemd-firstboot: add --force mode that replaces existing configuration.
257 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
258 that are linked to these places instead of copied. After all they are
259 constant vendor data.
261 * maybe add kernel cmdline params: to force random seed crediting
263 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
264 so that we make cgroup agent logic safe
266 * nspawn/machined: add API to invoke binary in container, then use that as
267 fallback in "machinectl shell"
269 * logind: rework pam_logind to also do a bus call in case of invocation from
270 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
271 behaviour selectable via pam module option.
274 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
275 - hook up machined/nspawn users with a varlink user query interface
276 - rollback when resize fails mid-operation
277 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
279 - shrink fs on logout?
280 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
281 - create on activate?
282 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
283 - communicate clearly when usb stick is safe to remove. probably involves
284 beefing up logind to make pam session close hook synchronous and wait until
285 systemd --user is shut down.
286 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
287 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine)
288 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
289 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
290 - fingerprint authentication, pattern authentication, …
291 - make sure "classic" user records can also be managed by homed
292 - description field for groups
293 - make size of $XDG_RUNTIME_DIR configurable in user record
294 - reuse pwquality magic in firstboot
295 - query password from kernel keyring first
296 - update even if record is "absent"
297 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
298 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
299 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
300 - make slice for users configurable (requires logind rework)
301 - logind: populate auto-login list bus property from PKCS#11 token
302 - when determining state of a LUKS home directory, check DM suspended sysfs file
304 * introduce a new per-process uuid, similar to the boot id, the machine id, the
305 invocation id, that is derived from process creds, specifically a hashed
306 combination of AT_RANDOM + getpid() + the starttime from
307 /proc/self/status. Then add these ids implicitly when logging. Deriving this
308 uuid from these three things has the benefit that it can be derived easily
309 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
312 * let's not GC a unit while its ratelimits are still pending
314 * when killing due to service watchdog timeout maybe detect whether target
315 process is under ptracing and then log loudly and continue instead.
317 * introduce a new group to own TPM devices
319 * make rfkill uaccess controllable by default, i.e. steal rule from
320 gnome-bluetooth and friends
322 * tweak journald context caching. In addition to caching per-process attributes
323 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
324 keyed by cgroup path, and guarded by ctime changes. This should provide us
325 with a nice speed-up on services that have many processes running in the same
328 * make MAINPID= message reception checks even stricter: if service uses User=,
329 then check sending UID and ignore message if it doesn't match the user or
332 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
335 * when importing an fs tree with machined, optionally apply userns-rec-chown
337 * when importing an fs tree with machined, complain if image is not an OS
339 * Maybe introduce a helper safe_exec() or so, which is to execve() which
340 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
341 to 1K implicitly, unless explicitly opted-out.
343 * rework seccomp/nnp logic that even if User= is used in combination with
344 a seccomp option we don't have to set NNP. For that, change uid first whil
345 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
347 * add a concept for automatically loading per-unit secrets off disk and
348 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
349 ConfigurationDirectory=.
351 * when no locale is configured, default to UEFI's PlatformLang variable
353 * bootctl,sd-boot: actually honour the "architecture" key
355 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
356 usefaultd() and make systemd-analyze check for it.
358 * paranoia: whenever we process passwords, call mlock() on the memory
359 first. i.e. look for all places we use free_and_erasep() and
360 augment them with mlock(). Also use MADV_DONTDUMP.
362 * Move RestrictAddressFamily= to the new cgroup create socket
364 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
367 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
368 log.c and sd-journal-send
370 * optionally: turn on cgroup delegation for per-session scope units
372 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
374 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
375 can add in file system drivers and such
377 * sd-boot: optionally, show boot menu when previous default boot item has
378 non-zero "tries done" count
380 * introduce an option (or replacement) for "systemctl show" that outputs all
381 properties as JSON, similar to busctl's new JSON output. In contrast to that
382 it should skip the variant type string though.
384 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
385 contains some identifier for the project, which allows us to include
386 clickable links to source files generating these log messages. The identifier
387 could be some abberviated URL prefix or so (taking inspiration from Go
388 imports). For example, for systemd we could use
389 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
390 sufficient to build a link by prefixing "http://" and suffixing the
393 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
394 make clickable links from log messages carrying a MESSAGE_ID, that lead to
395 some explanatory text online.
397 * maybe extend .path units to expose fanotify() per-mount change events
399 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
400 output of "systemctl list-units" slightly by showing the tree structure of
401 the slices, and the units attached to them.
403 * the a-posteriori stopping of units bound to units that disappeared logic
404 should be reworked: there should be a queue of units, and we should only
405 enqueue stop jobs from a defer event that processes queue instead of
406 right-away when we find a unit that is bound to one that doesn't exist
407 anymore. (similar to how the stop-unneeded queue has been reworked the same
410 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
411 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
412 for hangup or ^D before passing on the EOF.
414 * When reloading configuration PID 1 should reset all its properties to the
415 original defaults before calling parse_config()
417 * nspawn: greater control over selinux label?
419 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
422 1. add resume_offset support to the resume code (i.e. support swap files
424 2. check if swap is on weird storage and refuse if so
425 3. add auto-detection of hibernation images
427 * cgroups: use inotify to get notified when somebody else modifies cgroups
428 owned by us, then log a friendly warning.
430 * beef up log.c with support for stripping ANSI sequences from strings, so that
431 it is OK to include them in log strings. This would be particularly useful so
432 that our log messages could contain clickable links for example for unit
433 files and suchlike we operate on.
435 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
437 * add attach --enable and attach --now (for attach+enable+start)
439 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
440 selected user is resolvable in the service even if it ships its own /etc/passwd)
442 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
443 other doesn't. What a disaster. Probably to exclude it. Also
444 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
447 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
448 usually IN_ATTRIB is the right way to watch deleted files, as the former only
449 fires when a file is actually removed from disk, i.e. the link count drops to
450 zero and is not open anymore, while the latter happens when a file is
451 unlinked from any dir.
453 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
455 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
457 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
459 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
460 files and directories that are left writable for a unit, and which are
461 removed after the unit goes down again. A bit like --ephemeral for
462 systemd-nspawn but for system services. If used together with RootImage= this
463 should reflink the image file itself.
465 Related: add Ephemeral=<path1> <path2> … which would allow marking
466 specific paths only like this.
468 * add CopyFile= or so as unit file setting that may be used to copy files or
469 directory trees from the host to the services RootImage= and RootDirectory=
470 environment. Which we can use for /etc/machine-id and in particular
471 /etc/resolv.conf. Should be smart and do something useful on read-only
472 images, for example fallback to read-only bind mounting the file instead.
474 * show invocation ID in systemd-run output
476 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
478 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
479 and so on, which would mean we could report errors and such.
481 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
484 * introduce DefaultSlice= or so in system.conf that allows changing where we
485 place our units by default, i.e. change system.slice to something
486 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
487 be moved somewhere else too. Finally machined and logind should get similar
488 options so that it is possible to move user session scopes and machines to a
489 different slice too by default. Usecase: people who want to put resources on
490 the entire system, with the exception of one specific service. See:
491 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
493 * maybe rework get_user_creds() to query the user database if $SHELL is used
494 for root, but only then.
496 * be stricter with fds we receive for the fdstore: close them asynchronously
498 * calenderspec: add support for week numbers and day numbers within a
499 year. This would allow us to define "bi-weekly" triggers safely.
501 * sd-bus: add vtable flag, that may be used to request client creds implicitly
502 and asynchronously before dispatching the operation
504 * make use of ethtool veth peer info in machined, for automatically finding out
505 host-side interface pointing to the container.
507 * add some special mode to LogsDirectory=/StateDirectory=… that allows
508 declaring these directories without necessarily pulling in deps for them, or
509 creating them when starting up. That way, we could declare that
510 systemd-journald writes to /var/log/journal, which could be useful when we
511 doing disk usage calculations and so on.
513 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
515 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
517 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
518 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
519 as the unit is running or has a job queued.
521 * support projid-based quota in machinectl for containers
523 * add a way to lock down cgroup migration: a boolean, which when set for a unit
524 makes sure the processes in it can never migrate out of it
526 * blog about fd store and restartable services
528 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
530 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
531 magic meaning and is no longer upgraded to something else if set explicitly.
533 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
534 make it lose its identity, i.e. be anonymous. For this we'd have to patch
535 through the whole tree to make all code deal with the case where no machine
538 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
539 suitable for processing with rrdtool. Add bus API to access this data, and
540 possibly implement a CPULoad property based on it.
542 * beef up pam_systemd to take unit file settings such as cgroups properties as
545 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
546 the quota of a the user indicated in User= via unit file settings, like the
547 other resource management concepts. Would mix nicely with DynamicUser=1. Or
548 alternatively, do this with projids, so that we can also cover services
549 running as root. Quota should probably cover all the special dirs such as
550 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
551 is set, plus the whole disk space any image configured with RootImage=.
553 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
554 disks to see if the UID is already in use.
556 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
557 for all units. It should be both a way to pin units into memory as well as a
558 wait to retrieve their exit data.
560 * expose IO accounting data on the bus, show it in systemd-run --wait and log
561 about it in the resource log message
563 * show whether a service has out-of-date configuration in "systemctl status" by
564 using mtime data of ConfigurationDirectory=.
566 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
567 creates a static, persistent user rather than a dynamic, transient user. We
568 can leverage code from sysusers.d for this.
570 * add some optional flag to ReadWritePaths= and friends, that has the effect
571 that we create the dir in question when the service is started. Example:
573 ReadWritePaths=:/var/lib/foobar
575 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
576 the sd-journal logging socket, and, if the timeout is set to 0, sets
577 O_NONBLOCK on it. That way people can control if and when to block for
580 * hostnamed: populate form factor data from a new hwdb database, so that old
581 yogas can be recognized as "convertible" too, even if they predate the DMI
582 "convertible" form factor
584 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
585 after all. Be strict however, only support the equivalent of nspawn's
586 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
589 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
590 the service cgroup, which is supposed to monitor the service, and when it
591 exits the service is considered failed by its monitor.
593 * track the per-service PAM process properly (i.e. as an additional control
594 process), so that it may be queried on the bus and everything.
596 * add a new "debug" job mode, that is propagated to unit_start() and for
597 services results in two things: we raise SIGSTOP right before invoking
598 execve() and turn off watchdog support. Then, use that to implement
599 "systemd-gdb" for attaching to the start-up of any system service in its
602 * gpt-auto logic: related to the above, maybe support a "secondary" root
603 partition, that is mounted to / and is writable, and where the actual root's
604 /usr is mounted into.
606 * 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
608 * drop nss-myhostname in favour of nss-resolve?
610 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
611 then use that for the setting used in user@.service. It should be understood
612 relative to the configured default value.
614 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
616 * enable LockMLOCK to take a percentage value relative to physical memory
618 * Permit masking specific netlink APIs with RestrictAddressFamily=
620 * nspawn: support that /proc, /sys/, /dev are pre-mounted
622 * define gpt header bits to select volatility mode
624 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
626 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
628 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
630 * ProtectKeyRing= to take keyring calls away
632 * RemoveKeyRing= to remove all keyring entries of the specified user
634 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
635 on PID 1 with the relevant signals, and makes relevant files in /sys and
636 /proc (such as the sysrq stuff) unavailable
638 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
640 * journalctl: make sure -f ends when the container indicated by -M terminates
642 * mount: automatically search for "main" partition of an image has multiple
645 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
646 find a way to map the User=/Group= of the service to the right name. This way
647 a user/group for a service only has to exist on the host for the right
650 * add bus API for creating unit files in /etc, reusing the code for transient units
652 * add bus API to remove unit files from /etc
654 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
656 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
657 kernel doesn't support linkat() that replaces existing files, currently)
659 * transient units: don't bother with actually setting unit properties, we
660 reload the unit file anyway
662 * journald: sigbus API via a signal-handler safe function that people may call
663 from the SIGBUS handler
665 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
667 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
668 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
670 * cache sd_event_now() result from before the first iteration...
672 * PID1: find a way how we can reload unit file configuration for
673 specific units only, without reloading the whole of systemd
675 * add an explicit parser for LimitRTPRIO= that verifies
676 the specified range and generates sane error messages for incorrect
679 * when we detect that there are waiting jobs but no running jobs, do something
681 * push CPUAffinity= also into the "cpuset" cgroup controller
683 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
685 * there's probably something wrong with having user mounts below /sys,
686 as we have for debugfs. for example, src/core/mount.c handles mounts
687 prefixed with /sys generally special.
688 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
690 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
692 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
694 * add a job mode that will fail if a transaction would mean stopping
695 running units. Use this in timedated to manage the NTP service
697 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
699 * The udev blkid built-in should expose a property that reflects
700 whether media was sensed in USB CF/SD card readers. This should then
701 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
702 picked up by systemd unless they contain a medium. This would mirror
703 the behaviour we already have for CD drives.
705 * networkd/udev: implement SR_IOV configuration in .link files:
706 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
708 * hostnamectl: show root image uuid
710 * Find a solution for SMACK capabilities stuff:
711 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
713 * "systemctl preset-all" should probably order the unit files it
714 operates on lexicographically before starting to work, in order to
715 ensure deterministic behaviour if two unit files conflict (like DMs
718 * synchronize console access with BSD locks:
719 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
721 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
722 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
724 * figure out when we can use the coarse timers
726 * add "systemctl start -v foobar.service" that shows logs of a service
727 while the start command runs. This is non-trivial to do without
728 races though, since we should flush out all journal messages before
729 returning from the "systemctl stop".
731 * 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
733 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
735 * maybe allow timer units with an empty Units= setting, so that they
736 can be used for resuming the system but nothing else.
738 * what to do about udev db binary stability for apps? (raw access is not an option)
740 * systemctl: if some operation fails, show log output?
742 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
743 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
745 * exponential backoff in timesyncd when we cannot reach a server
747 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
749 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
751 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
752 (throughout the codebase, not only PID1)
756 - service registration
757 - service/domain/types browsing
759 - DNS-SD service registration from socket units
760 - resolved should optionally register additional per-interface LLMNR
761 names, so that for the container case we can establish the same name
762 (maybe "host") for referencing the server, everywhere.
763 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
764 - hook up resolved with machined-based address resolution
766 * refcounting in sd-resolve is borked
768 * Add a new verb "systemctl top"
770 * add new gpt type for btrfs volumes
772 * support empty /etc boots nicely:
773 - nspawn/gpt-generator: introduce new gpt partition type for /usr
775 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
777 * a way for container managers to turn off getty starting via $container_headless= or so...
779 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
781 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
782 they run added to the initial transaction and thus confuse Type=idle.
784 * add bus api to query unit file's X fields.
786 * gpt-auto-generator:
787 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
788 - Make /home automount rather than mount?
790 * add generator that pulls in systemd-network from containers when
791 CAP_NET_ADMIN is set, more than the loopback device is defined, even
792 when it is otherwise off
794 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
796 * implement Distribute= in socket units to allow running multiple
797 service instances processing the listening socket, and open this up
800 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
801 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
802 should SIGSTOP all unit processes in a loop until all processes of
803 it are fully stopped. This can later be used for app management by
804 desktop UIs such as gnome-shell to freeze apps that are not visible
805 on screen, not unlike how job control works on the shell
808 - implement per-slice CPUFairScheduling=1 switch
809 - introduce high-level settings for RT budget, swappiness
810 - how to reset dynamically changed unit cgroup attributes sanely?
811 - when reloading configuration, apply new cgroup configuration
812 - when recursively showing the cgroup hierarchy, optionally also show
813 the hierarchies of child processes
816 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
818 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
820 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
822 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
824 * 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
826 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
828 * If we try to find a unit via a dangling symlink, generate a clean
829 error. Currently, we just ignore it and read the unit from the search
832 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
834 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
836 * load .d/*.conf dropins for device units
840 - GetAllProperties() on a non-existing object does not result in a failure currently
841 - port to sd-resolve for connecting to TCP dbus servers
842 - 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
843 - see if we can drop more message validation on the sending side
844 - add API to clone sd_bus_message objects
845 - longer term: priority inheritance
847 - NameLost/NameAcquired obsolete
850 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
853 - allow multiple signal handlers per signal?
854 - document chaining of signal handler for SIGCHLD and child handlers
855 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
857 * investigate endianness issues of UUID vs. GUID
859 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
860 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
862 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
864 * add a pam module that on password changes updates any LUKS slot where the password matches
867 - add unit tests for config_parse_device_allow()
869 * seems that when we follow symlinks to units we prefer the symlink
870 destination path over /etc and /usr. We should not do that. Instead
871 /etc should always override /run+/usr and also any symlink
874 * when isolating, try to figure out a way how we implicitly can order
875 all units we stop before the isolating unit...
877 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
879 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
880 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
881 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
883 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
884 that the boot loader should be installed to the ESP. Define a way
885 how an installer can figure out whether a BLS compliant boot loader
888 * think about requeuing jobs when daemon-reload is issued? usecase:
889 the initrd issues a reload after fstab from the host is accessible
890 and we might want to requeue the mounts local-fs acquired through
893 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
895 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
897 * shutdown logging: store to EFI var, and store to USB stick?
899 * merge unit_kill_common() and unit_kill_context()
902 - honor language efi variables for default language selection (if there are any?)
903 - honor timezone efi variables for default timezone selection (if there are any?)
904 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
906 - recognize the case when not booted on EFI
908 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
910 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
912 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
915 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
916 - logind: wakelock/opportunistic suspend support
917 - Add pretty name for seats in logind
918 - logind: allow showing logout dialog from system?
919 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
920 - if pam_systemd is invoked by su from a process that is outside of a
921 any session we should probably just become a NOP, since that's
922 usually not a real user session but just some system code that just
924 - logind: make the Suspend()/Hibernate() bus calls wait for the for
925 the job to be completed. before returning, so that clients can wait
926 for "systemctl suspend" to finish to know when the suspending is
928 - logind: when the power button is pressed short, just popup a
929 logout dialog. If it is pressed for 1s, do the usual
930 shutdown. Inspiration are Macs here.
931 - expose "Locked" property on logind sesison objects
932 - maybe allow configuration of the StopTimeout for session scopes
933 - rename session scope so that it includes the UID. THat way
934 the session scope can be arranged freely in slices and we don't have
935 make assumptions about their slice anymore.
936 - follow PropertiesChanged state more closely, to deal with quick logouts and
938 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
941 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
942 - journald: also get thread ID from client, plus thread name
943 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
944 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
945 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
946 - declare the local journal protocol stable in the wiki interface chart
947 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
948 - journald: when dropping msgs due to ratelimit make sure to write
949 "dropped %u messages" not only when we are about to print the next
950 message that works, but already after a short timeout
951 - check if we can make journalctl by default use --follow mode inside of less if called without args?
952 - maybe add API to send pairs of iovecs via sd_journal_send
953 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
954 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
955 and !FOOBAR for events without FOOBAR.
956 - journal: store timestamp of journal_file_set_offline() int he header,
957 so it is possible to display when the file was last synced.
958 - 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.
959 - journal: find a way to allow dropping history early, based on priority, other rules
960 - journal: When used on NFS, check payload hashes
961 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
962 - refuse taking lower-case variable names in sd_journal_send() and friends.
963 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
964 - journal: deal nicely with byte-by-byte copied files, especially regards header
965 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
966 - Replace utmp, wtmp, btmp, and lastlog completely with journal
967 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
968 - when a kernel driver logs in a tight loop, we should ratelimit that too.
969 - journald: optionally, log debug messages to /run but everything else to /var
970 - journald: when we drop syslog messages because the syslog socket is
971 full, make sure to write how many messages are lost as first thing
972 to syslog when it works again.
973 - journald: allow per-priority and per-service retention times when rotating/vacuuming
974 - journald: make use of uid-range.h to managed uid ranges to split
976 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
977 - improve journalctl performance by loading journal files
978 lazily. Encode just enough information in the file name, so that we
979 do not have to open it to know that it is not interesting for us, for
980 the most common operations.
981 - man: document that corrupted journal files is nothing to act on
982 - rework journald sigbus stuff to use mutex
983 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
984 services that run under their own user ids, and use User= (but only
985 in a world where userns is ubiquitous since otherwise we cannot
986 invoke those daemons on the host AND in a container anymore). Also,
987 if LimitNPROC= is used without User= we should warn and refuse
989 - journalctl --verify: don't show files that are currently being
990 written to as FAIL, but instead show that their are being written to.
991 - add journalctl -H that talks via ssh to a remote peer and passes through
993 - add a version of --merge which also merges /var/log/journal/remote
994 - journalctl: -m should access container journals directly by enumerating
995 them via machined, and also watch containers coming and going.
996 Benefit: nspawn --ephemeral would start working nicely with the journal.
997 - assign MESSAGE_ID to log messages about failed services
999 * add a test if all entries in the catalog are properly formatted.
1000 (Adding dashes in a catalog entry currently results in the catalog entry
1001 being silently skipped. journalctl --update-catalog must warn about this,
1002 and we should also have a unit test to check that all our message are OK.)
1005 - document that deps in [Unit] sections ignore Alias= fields in
1006 [Install] units of other units, unless those units are disabled
1007 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
1008 - document that service reload may be implemented as service reexec
1009 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1010 - document systemd-journal-flush.service properly
1011 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1012 - man: document the very specific env the shutdown drop-in tools live in
1013 - man: add more examples to man pages
1014 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
1015 - document root=gpt-auto properly
1018 - add systemctl switch to dump transaction without executing it
1019 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1020 - "systemctl disable" on a static unit prints no message and does
1021 nothing. "systemctl enable" does nothing, and gives a bad message
1022 about it. Should fix both to print nice actionable messages.
1023 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1024 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1025 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1026 - systemctl: "Journal has been rotated since unit was started." message is misleading
1027 - systemctl status output should include list of triggering units and their status
1030 - "systemctl mask" should find all names by which a unit is accessible
1031 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1034 - timer units should get the ability to trigger when:
1036 - Modulate timer frequency based on battery state
1038 * add libsystemd-password or so to query passwords during boot using the password agent logic
1040 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1042 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1044 * make repeated alt-ctrl-del presses printing a dump
1046 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1048 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1051 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1052 with seccomp. That should provide us with a useful log buffer that
1053 systemd can log to during early boot, and disconnect container logs
1054 from the kernel's logs.
1055 - as soon as networkd has a bus interface, hook up --network-interface=,
1056 --network-bridge= with networkd, to trigger netdev creation should an
1057 interface be missing
1058 - a nice way to boot up without machine id set, so that it is set at boot
1059 automatically for supporting --ephemeral. Maybe hash the host machine id
1060 together with the machine name to generate the machine id for the container
1061 - fix logic always print a final newline on output.
1062 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1063 - should optionally support receiving WATCHDOG=1 messages from its payload
1065 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1066 running, remove them when shut down.
1069 - refuse mounting over a mount point
1070 - automatically discover .roothash files in dissect, similarly to nspawn
1073 - add an API so that libvirt-lxc can inform us about network interfaces being
1074 removed or added to an existing machine
1075 - "machinectl migrate" or similar to copy a container from or to a
1076 difference host, via ssh
1077 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1078 "machinectl start" with a new --ephemeral switch
1079 - "machinectl status" should also show internal logs of the container in
1081 - "machinectl history"
1083 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1084 shell in it, and marks it read-only after use
1087 - cryptsetup-generator: allow specification of passwords in crypttab itself
1088 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1090 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1091 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1093 * add a dependency on standard-conf.xml and other included files to man pages
1095 * MountFlags=shared acts as MountFlags=slave right now.
1097 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1099 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1104 - add trigger --subsystem-match=usb/usb_device device
1105 - reimport udev db after MOVE events for devices without dev_t
1107 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1109 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1112 - save coredump in Windows/Mozilla minidump format
1113 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1115 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1117 * be able to specify a forced restart of service A where service B depends on, in case B
1118 needs to be auto-respawned?
1121 - apply "x" on "D" too (see patch from William Douglas)
1122 - instead of ignoring unknown fields, reject them.
1123 - creating new directories/subvolumes/fifos/device nodes
1124 should not follow symlinks. None of the other adjustment or creation
1125 calls follow symlinks.
1127 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1129 * verify that the AF_UNIX sockets of a service in the fs still exist
1130 when we start a service in order to avoid confusion when a user
1131 assumes starting a service is enough to make it accessible
1133 * Make it possible to set the keymap independently from the font on
1134 the kernel cmdline. Right now setting one resets also the other.
1136 * and a dbus call to generate target from current state
1138 * write blog stories about:
1139 - hwdb: what belongs into it, lsusb
1140 - enabling dbus services
1141 - how to make changes to sysctl and sysfs attributes
1143 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1144 - testing with Harald's awesome test kit
1146 - how to develop against journal browsing APIs
1147 - the journal HTTP iface
1148 - non-cgroup resource management
1149 - dynamic resource management with cgroups
1150 - refreshed, longer missions statement
1151 - calendar time events
1152 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1153 - how to create your own target
1154 - instantiated apache, dovecot and so on
1155 - hooking a script into various stages of shutdown/rearly booot
1157 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1159 * dot output for --test showing the 'initial transaction'
1162 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1163 log both units as UNIT=, so that journalctl -u triggers on both.
1164 - generate better errors when people try to set transient properties
1165 that are not supported...
1166 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1167 - maybe introduce WantsMountsFor=? Usecase:
1168 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1169 - recreate systemd's D-Bus private socket file on SIGUSR2
1170 - move PAM code into its own binary
1171 - when we automatically restart a service, ensure we restart its rdeps, too.
1172 - hide PAM options in fragment parser when compile time disabled
1173 - Support --test based on current system state
1174 - 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().
1175 - after deserializing sockets in socket.c we should reapply sockopts and things
1176 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1177 currently is properly synchronous, Reexec() is weird, because we
1178 cannot delay the response properly until we are back, so instead of
1179 being properly synchronous we just keep open the fd and close it
1180 when done. That means clients do not get a successful method reply,
1181 but much rather a disconnect on success.
1182 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1183 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1186 - allow port=0 in .socket units
1187 - maybe introduce ExecRestartPre=
1188 - add ReloadSignal= for configuring a reload signal to use
1189 - implement Register= switch in .socket units to enable registration
1190 in Avahi, RPC and other socket registration services.
1191 - allow Type=simple with PIDFile=
1192 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1193 - allow writing multiple conditions in unit files on one line
1194 - introduce Type=pid-file
1195 - introduce mix of BindTo and Requisite
1196 - add a concept of RemainAfterExit= to scope units
1197 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1198 - add verification of [Install] section to systemd-analyze verify
1201 - Make sure ID_PATH is always exported and complete for
1202 network devices where possible, so we can safely rely
1206 - add support for more attribute types
1207 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1210 - add more keys to [Route] and [Address] sections
1211 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1212 - add reduced [Link] support to .network files
1213 - properly handle routerless dhcp leases
1214 - work with non-Ethernet devices
1215 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1216 - the DHCP lease data (such as NTP/DNS) is still made available when
1217 a carrier is lost on a link. It should be removed instantly.
1218 - expose in the API the following bits:
1219 - option 15, domain name
1220 - option 12, hostname and/or option 81, fqdn
1221 - option 123, 144, geolocation
1222 - option 252, configure http proxy (PAC/wpad)
1223 - provide a way to define a per-network interface default metric value
1224 for all routes to it. possibly a second default for DHCP routes.
1225 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1226 support Name=foo*|bar*|baz ?
1227 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1228 - whenever uplink info changes, make DHCP server send out FORCERENEW
1231 - figure out how much we can increase Maximum Message Size
1234 - add functions to set previously stored IPv6 addresses on startup and get
1235 them at shutdown; store them in client->ia_na
1236 - write more test cases
1237 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1238 - implement support for temporary adressess (IA_TA)
1239 - implement dhcpv6 authentication
1240 - investigate the usefulness of Confirm messages; i.e. are there any
1241 situations where the link changes without any loss in carrier detection
1243 - some servers don't do rapid commit without a filled in IA_NA, verify
1250 - natively watch for dbus-*.service symlinks (PENDING)
1251 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1253 * make cryptsetup lower --iter-time
1255 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1257 * /usr/bin/service should actually show the new command line
1259 * 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=
1261 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1263 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1265 * register catalog database signature as file magic
1267 * zsh shell completion:
1268 - <command> <verb> -<TAB> should complete options, but currently does not
1269 - systemctl add-wants,add-requires
1271 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1272 * If timer has just OnInactiveSec=..., it should fire after a specified time
1273 after being started.
1277 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1279 * check for strerror(r) instead of strerror(-r)
1283 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1285 * use secure_getenv() instead of getenv() where appropriate
1287 * link up selected blog stories from man pages and unit files Documentation= fields
1288 String is not UTF-8 clean, ignoring assignment
