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.
9 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
13 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
15 * rework mount.c and swap.c to follow proper state enumeration/deserialization
16 semantics, like we do for device.c now
20 * nss-systemd: also synthesize shadow records for users/groups
22 * nspawn: move "incoming mount" directory to /run/host, move "inaccessible"
23 nodes to /run/host, move notify socket (for sd_notify() between payload and
26 * make use of new glibc 2.32 APIs sigabbrev_np() and strerrorname_np().
28 * cryptsetup: if keyfile specified in crypttab is AF_UNIX socket, connect to it
29 and read from it (like we do elsewhere with READ_FULL_FILE_CONNECT_SOCKET)
31 * when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or
32 so, freeze the payload too.
34 * repart: support setting up dm-integrity with HMAC
36 * add /etc/integritytab, to support dm-integrity setups. In particular those
37 with HMAC as hash function, so that we can have a protected /home without
38 encryption (leaving encryption to the individual dirs/homed).
40 * complement root=, rootflags=, rootfstype= with rootsubdir= which allows
41 mounting a subdir of the root fs as actual root. This can be used as
42 fstype-agnostic version of btrfs' rootflags=subvol=foobar.
44 * Support ProtectProc= or so, using: https://patchwork.kernel.org/cover/11310197/
46 * if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
48 * build short web pages out of each catalog entry, build them along with man
49 pages, and include hyperlinks to them in the journal output
51 * machined: add API to acquire UID range. add API to mount/dissect loopback
52 file. Both protected by PK. Then make nspawn use these APIs to run
53 unprivileged containers. i.e. push the truly privileged bits into machined,
54 so that the client side can remain entirely unprivileged, with SUID or
57 * journald: do journal file writing out-of-process, with one writer process per
58 client UID, so that synthetic hash table collisions can slow down a specific
59 user's journal stream down but not the others.
61 * add "throttling" to sd-event event sources: optionally, when we wake up too
62 often for one, let's turn it off entirely for a while. Use that for the
63 /proc/self/mountinfo logic.
65 * move our systemd-user PAM snippet to /usr/, which PAM appears to support
68 * nspawn: support time namespaces
70 * systemd-firstboot: make sure to always use chase_symlinks() before
73 * add ConditionSecurity=tpm2
75 * Remove any support for booting without /usr pre-mounted in the initrd entirely.
76 Update INITRD_INTERFACE.md accordingly.
78 * pid1: Move to tracking of main pid/control pid of units per pidfd
80 * pid1: support new clone3() fork-into-cgroup feature
82 * pid1: also remove PID files of a service when the service starts, not just
85 * make us use dynamically fewer deps for containers in general purpose distros:
86 o turn into dlopen() deps:
89 - p11-kit-trust (always)
90 - kmod-libs (only when called from PID 1)
91 - cryptsetup-libs (only in RootImage= handling in PID 1, but not in systemd-cryptsetup)
93 - libpam (only when called from PID 1)
94 - bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are,
95 since they are so basic and our defaults)
96 o move into separate libsystemd-shared-iptables.so .so
97 - iptables-libs (only used by nspawn + networkd)
99 * seccomp: when SystemCallArchitectures=native is set then don't install any
100 other seccomp filters for any of the other archs, in order to reduce the
101 number of seccomp filters we install needlessly.
103 * seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can.
104 Apparently kernel performance is much better with fewer larger seccomp
105 filters than with more smaller seccomp filters.
107 * systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
108 mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
110 * All tools that support --root= should also learn --image= so that they can
111 operate on disk images directly. Specifically: bootctl, systemctl,
112 coredumpctl. (Already done: systemd-nspawn, systemd-firstboot,
113 systemd-repart, systemd-tmpfiles, systemd-sysusers, journalctl)
115 * seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out
117 * seccomp: don't install filters for ABIs that are masked anyway for the
120 * seccomp: maybe merge all filters we install into one with that libseccomp API that allows merging.
122 * per-service credential system. Specifically: add LoadCredential= (for loading
123 cred from file), AcquireCredential= (for asking user for cred, via
124 ask-password), PassCredential= (for passing on credential systemd itself
125 got). Then, place credentials in a per-service, immutable ramfs instance (so
126 that it cannot be swapped out), destroy after use. Also pass via keyring
127 (with graceful fallback to cover for containers). Define CredentialPath= for
128 defining subdir of /run/credentials/ where to place it. Set $CREDENTIAL_PATH
129 env var for services to the result. Also pass via fd passing (optionally).
131 * homed: add native recovery key support. use 48 lowercase modhex characters
132 (192bit), show qr code of it, include pattern expression in user record.
134 * homed: introduce "degraded" state for home directories that weren't cleanly
135 unmounted (use xattr we add and remove on the loop back file)
137 * homed: during login resize fs automatically towards size goal. Specifically,
138 resize to diskSize if possible, but leave a certain amount (configured by a
139 new value diskLeaveFreeSize) of space free on the backing fs.
141 * homed: permit multiple user record signing keys to be used locally, and pick
142 the right one for signing records automatically depending on a pre-existing
145 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
146 and insert a local signature instead.
148 * homed: as an extension to the directory+subvolume backend: if located on
149 especially marked fs, then sync down password into LUKS header of that fs,
150 and always verify passwords against it too. Bootstrapping is a problem
151 though: if no one is logged in (or no other user even exists yet), how do you
152 unlock the volume in order to create the first user and add the first pw.
154 * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
156 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
159 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
162 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
163 root partitions, do an strverscmp() on the partition label and boot
164 first. That is inspired how sd-boot figures out which kernel to boot, and
165 thus allows defining OS images which can be A/B updated and we default to the
166 newest version automatically, both in nspawn and in sd-boot
168 * cryptsetup: support FIDO2 tokens for deriving keys (i.e. do what homed can do
169 also in plain cryptsetup)
171 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
174 * homed/userdb: distinguish passwords and recovery keys in the records, since
175 we probably want to use different PBKDF algorithms/settings for them:
176 passwords have low entropy but recovery keys should have good entropy key
177 hence we can make them quicker to work.
180 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
181 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
182 - make it operate on loopback files, dissecting enough to find ESP to operate on
184 * Maybe add a separate GPT partition type to the discoverable partition spec
185 for "hibernate" partitions, that are exactly like swap partitions but only
186 activated right before hibernation and thus never used for regular swapping.
188 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
189 allow so that systemd survives
191 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
192 "base64:" prefix. Useful in particular for pkcs11 mode.
194 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
195 systemd-makefs.service instead.
197 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
198 with matches, then activate app through that passing socket over
200 * unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
202 - port sd_id128_get_machine_app_specific() over from khash
203 - port resolved over from libgcrypt (DNSSEC code)
204 - port journald + fsprg over from libgcrypt
205 - port importd over from libgcrypt
206 - when that's done: kill khash.c
207 - when that's done: kill gnutls support in resolved
209 * kill zenata, all hail weblate?
211 * when we resize disks (homed?) always round up to 4K sectors, not 512K
213 * add growvol and makevol options for /etc/crypttab, similar to
214 x-systemd.growfs and x-systemd-makefs.
216 * hook up the TPM to /etc/crypttab, with a new option that is similar to the
217 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
218 unsealed from the TPM. Optionally, if TPM is not available fall back to
219 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
220 that the device paths stay the same, regardless if crypto is used or not.
222 * systemd-repart: by default generate minimized partition tables (i.e. tables
223 that only cover the space actually used, excluding any free space at the
224 end), in order to maximize dd'ability. Requires libfdisk work, see
225 https://github.com/karelzak/util-linux/issues/907
227 * systemd-repart: MBR partition table support. Care needs to be taken regarding
228 Type=, so that partition definitions can sanely apply to both the GPT and the
229 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
230 for the two partition types explicitly. And provide an internal mapping so
231 that "Type=linux-generic" maps to the right types for both partition tables
234 * systemd-repart: allow sizing partitions as factor of available RAM, so that
235 we can reasonably size swap partitions for hibernation.
237 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
239 * systemd-repart: allow boolean option that ensures that if existing partition
240 doesn't exist within the configured size bounds the whole command fails. This
241 is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
242 of repart files for the case where ESP is large enough and one where it isn't
243 and XBOOTLDR is added in instead. Then apply the former first, and if it
244 fails to apply use the latter.
246 * systemd-repart: add per-partition option to never reuse existing partition
247 and always create anew even if matching partition already exists.
249 * systemd-repart: add per-partition option to fail if partition already exist,
250 i.e. is not added new. Similar, add option to fail if partition does not exist yet.
252 * systemd-repart: allow disabling growing of specific partitions, or making
253 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
255 * systemd-repart: make it a static checker during early boot for existence and
256 absence of other partitions for trusted boot environments
258 * userdb: allow username prefix searches in varlink API, allow realname and
259 realname substr searches in varlink API
261 * userdb: allow uid/gid range checks
263 * userdb: allow existence checks
265 * pid1: activation by journal search expression
267 * when switching root from initrd to host, set the machine_id env var so that
268 if the host has no machine ID set yet we continue to use the random one the
271 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
272 it fo reaping assigned but unknown children. This needs to some special care
273 to operate somewhat sensibly in light of priorities: P_ALL will return
274 arbitrary processes, regardless of the priority we want to watch them with,
275 hence on each event loop iteration check all processes which we shall watch
276 with higher prio explicitly, and then watch the entire rest with P_ALL.
278 * tweak sd-event's child watching: keep a prioq of children to watch and use
279 waitid() only on the children with the highest priority until one is waitable
280 and ignore all lower-prio ones from that point on
282 * maybe introduce xattrs that can be set on the root dir of the root fs
283 partition that declare the volatility mode to use the image in. Previously I
284 thought marking this via GPT partition flags but that's not ideal since
285 that's outside of the LUKS encryption/verity verification, and we probably
286 shouldn't operate in a volatile mode unless we got told so from a trusted
289 * figure out automatic partition discovery when combining writable root dir
292 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
293 may be used to mark a whole binary as non-coredumpable. Would fix:
294 https://bugs.freedesktop.org/show_bug.cgi?id=69447
296 * teach parse_timestamp() timezones like the calendar spec already knows it
298 * beef up hibernation to optionally do swapon/swapoff immediately before/after
301 * beef up s2h to implement a battery watch loop: instead of entering
302 hibernation unconditionally after coming back from resume make a decision
303 based on the battery load level: if battery level is above a specific
304 threshold, go to suspend again, only hibernate if below it. This means we'd
305 stick to suspend usually, but fall back to hibernation only when battery runs
306 empty (well, subject to our sampling interval). Related to this, check if we
307 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
308 i.e. see if it can wake up machines from suspend, so that we could resume
309 automatically when the system is low on power and move automatically to
310 hibernation mode. (see
311 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
313 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
316 * add an explicit "vertical" mode to format-table, so that "systemctl
317 status"-like outputs (i.e. with a series of field names left and values
318 right) become genuine first class citizens, and we gain automatic, sane JSON
321 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
322 that are linked to these places instead of copied. After all they are
323 constant vendor data.
325 * maybe add kernel cmdline params: to force random seed crediting
327 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
328 so that we make cgroup agent logic safe
330 * nspawn/machined: add API to invoke binary in container, then use that as
331 fallback in "machinectl shell"
333 * logind: rework pam_logind to also do a bus call in case of invocation from
334 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
335 behaviour selectable via pam module option.
338 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
339 - rollback when resize fails mid-operation
340 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
342 - shrink fs on logout?
343 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
344 - create on activate?
345 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
346 - communicate clearly when usb stick is safe to remove. probably involves
347 beefing up logind to make pam session close hook synchronous and wait until
348 systemd --user is shut down.
349 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
350 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk
351 images (and btrfs snapshots of subvolumes) (think: time machine)
352 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
353 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
354 - fingerprint authentication, pattern authentication, …
355 - make sure "classic" user records can also be managed by homed
356 - make size of $XDG_RUNTIME_DIR configurable in user record
357 - query password from kernel keyring first
358 - update even if record is "absent"
359 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
360 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
361 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
362 - make slice for users configurable (requires logind rework)
363 - logind: populate auto-login list bus property from PKCS#11 token
364 - when determining state of a LUKS home directory, check DM suspended sysfs file
365 - introduce API for "making room", that grows/shrinks home directory
366 according to elastic parameters, discards blocks, and removes additional snapshots. Call it
367 either from UI when disk space gets low
369 * introduce a new per-process uuid, similar to the boot id, the machine id, the
370 invocation id, that is derived from process creds, specifically a hashed
371 combination of AT_RANDOM + getpid() + the starttime from
372 /proc/self/status. Then add these ids implicitly when logging. Deriving this
373 uuid from these three things has the benefit that it can be derived easily
374 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
377 * let's not GC a unit while its ratelimits are still pending
379 * when killing due to service watchdog timeout maybe detect whether target
380 process is under ptracing and then log loudly and continue instead.
382 * introduce a new group to own TPM devices
384 * make rfkill uaccess controllable by default, i.e. steal rule from
385 gnome-bluetooth and friends
387 * tweak journald context caching. In addition to caching per-process attributes
388 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
389 keyed by cgroup path, and guarded by ctime changes. This should provide us
390 with a nice speed-up on services that have many processes running in the same
393 * make MAINPID= message reception checks even stricter: if service uses User=,
394 then check sending UID and ignore message if it doesn't match the user or
397 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
400 * when importing an fs tree with machined, optionally apply userns-rec-chown
402 * when importing an fs tree with machined, complain if image is not an OS
404 * Maybe introduce a helper safe_exec() or so, which is to execve() which
405 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
406 to 1K implicitly, unless explicitly opted-out.
408 * rework seccomp/nnp logic that even if User= is used in combination with
409 a seccomp option we don't have to set NNP. For that, change uid first whil
410 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
412 * add a concept for automatically loading per-unit secrets off disk and
413 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
414 ConfigurationDirectory=.
416 * when no locale is configured, default to UEFI's PlatformLang variable
418 * bootctl,sd-boot: actually honour the "architecture" key
420 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
421 usefaultd() and make systemd-analyze check for it.
423 * paranoia: whenever we process passwords, call mlock() on the memory
424 first. i.e. look for all places we use free_and_erasep() and
425 augment them with mlock(). Also use MADV_DONTDUMP.
427 * Move RestrictAddressFamily= to the new cgroup create socket
429 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
432 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
433 log.c and sd-journal-send
435 * optionally: turn on cgroup delegation for per-session scope units
437 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
439 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
440 can add in file system drivers and such
442 * sd-boot: optionally, show boot menu when previous default boot item has
443 non-zero "tries done" count
445 * introduce an option (or replacement) for "systemctl show" that outputs all
446 properties as JSON, similar to busctl's new JSON output. In contrast to that
447 it should skip the variant type string though.
449 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
450 contains some identifier for the project, which allows us to include
451 clickable links to source files generating these log messages. The identifier
452 could be some abberviated URL prefix or so (taking inspiration from Go
453 imports). For example, for systemd we could use
454 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
455 sufficient to build a link by prefixing "http://" and suffixing the
458 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
459 make clickable links from log messages carrying a MESSAGE_ID, that lead to
460 some explanatory text online.
462 * maybe extend .path units to expose fanotify() per-mount change events
464 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
465 output of "systemctl list-units" slightly by showing the tree structure of
466 the slices, and the units attached to them.
468 * the a-posteriori stopping of units bound to units that disappeared logic
469 should be reworked: there should be a queue of units, and we should only
470 enqueue stop jobs from a defer event that processes queue instead of
471 right-away when we find a unit that is bound to one that doesn't exist
472 anymore. (similar to how the stop-unneeded queue has been reworked the same
475 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
476 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
477 for hangup or ^D before passing on the EOF.
479 * When reloading configuration PID 1 should reset all its properties to the
480 original defaults before calling parse_config()
482 * nspawn: greater control over selinux label?
484 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
487 1. add resume_offset support to the resume code (i.e. support swap files
489 2. check if swap is on weird storage and refuse if so
490 3. add auto-detection of hibernation images
492 * cgroups: use inotify to get notified when somebody else modifies cgroups
493 owned by us, then log a friendly warning.
495 * beef up log.c with support for stripping ANSI sequences from strings, so that
496 it is OK to include them in log strings. This would be particularly useful so
497 that our log messages could contain clickable links for example for unit
498 files and suchlike we operate on.
500 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
502 * add attach --enable and attach --now (for attach+enable+start)
504 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
505 selected user is resolvable in the service even if it ships its own /etc/passwd)
507 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
508 other doesn't. What a disaster. Probably to exclude it. Also
509 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
512 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
513 usually IN_ATTRIB is the right way to watch deleted files, as the former only
514 fires when a file is actually removed from disk, i.e. the link count drops to
515 zero and is not open anymore, while the latter happens when a file is
516 unlinked from any dir.
518 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
520 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
522 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
524 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
525 files and directories that are left writable for a unit, and which are
526 removed after the unit goes down again. A bit like --ephemeral for
527 systemd-nspawn but for system services. If used together with RootImage= this
528 should reflink the image file itself.
530 Related: add Ephemeral=<path1> <path2> … which would allow marking
531 specific paths only like this.
533 * add CopyFile= or so as unit file setting that may be used to copy files or
534 directory trees from the host to the services RootImage= and RootDirectory=
535 environment. Which we can use for /etc/machine-id and in particular
536 /etc/resolv.conf. Should be smart and do something useful on read-only
537 images, for example fall back to read-only bind mounting the file instead.
539 * show invocation ID in systemd-run output
541 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
543 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
544 and so on, which would mean we could report errors and such.
546 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
549 * introduce DefaultSlice= or so in system.conf that allows changing where we
550 place our units by default, i.e. change system.slice to something
551 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
552 be moved somewhere else too. Finally machined and logind should get similar
553 options so that it is possible to move user session scopes and machines to a
554 different slice too by default. Usecase: people who want to put resources on
555 the entire system, with the exception of one specific service. See:
556 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
558 * maybe rework get_user_creds() to query the user database if $SHELL is used
559 for root, but only then.
561 * be stricter with fds we receive for the fdstore: close them asynchronously
563 * calenderspec: add support for week numbers and day numbers within a
564 year. This would allow us to define "bi-weekly" triggers safely.
566 * sd-bus: add vtable flag, that may be used to request client creds implicitly
567 and asynchronously before dispatching the operation
569 * make use of ethtool veth peer info in machined, for automatically finding out
570 host-side interface pointing to the container.
572 * add some special mode to LogsDirectory=/StateDirectory=… that allows
573 declaring these directories without necessarily pulling in deps for them, or
574 creating them when starting up. That way, we could declare that
575 systemd-journald writes to /var/log/journal, which could be useful when we
576 doing disk usage calculations and so on.
578 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
580 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
582 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
583 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
584 as the unit is running or has a job queued.
586 * support projid-based quota in machinectl for containers
588 * add a way to lock down cgroup migration: a boolean, which when set for a unit
589 makes sure the processes in it can never migrate out of it
591 * blog about fd store and restartable services
593 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
595 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
596 magic meaning and is no longer upgraded to something else if set explicitly.
598 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
599 make it lose its identity, i.e. be anonymous. For this we'd have to patch
600 through the whole tree to make all code deal with the case where no machine
603 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
604 suitable for processing with rrdtool. Add bus API to access this data, and
605 possibly implement a CPULoad property based on it.
607 * beef up pam_systemd to take unit file settings such as cgroups properties as
610 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
611 the quota of a the user indicated in User= via unit file settings, like the
612 other resource management concepts. Would mix nicely with DynamicUser=1. Or
613 alternatively, do this with projids, so that we can also cover services
614 running as root. Quota should probably cover all the special dirs such as
615 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
616 is set, plus the whole disk space any image configured with RootImage=.
618 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
619 disks to see if the UID is already in use.
621 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
622 for all units. It should be both a way to pin units into memory as well as a
623 wait to retrieve their exit data.
625 * expose IO accounting data on the bus, show it in systemd-run --wait and log
626 about it in the resource log message
628 * show whether a service has out-of-date configuration in "systemctl status" by
629 using mtime data of ConfigurationDirectory=.
631 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
632 creates a static, persistent user rather than a dynamic, transient user. We
633 can leverage code from sysusers.d for this.
635 * add some optional flag to ReadWritePaths= and friends, that has the effect
636 that we create the dir in question when the service is started. Example:
638 ReadWritePaths=:/var/lib/foobar
640 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
641 the sd-journal logging socket, and, if the timeout is set to 0, sets
642 O_NONBLOCK on it. That way people can control if and when to block for
645 * hostnamed: populate form factor data from a new hwdb database, so that old
646 yogas can be recognized as "convertible" too, even if they predate the DMI
647 "convertible" form factor
649 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
650 after all. Be strict however, only support the equivalent of nspawn's
651 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
654 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
655 the service cgroup, which is supposed to monitor the service, and when it
656 exits the service is considered failed by its monitor.
658 * track the per-service PAM process properly (i.e. as an additional control
659 process), so that it may be queried on the bus and everything.
661 * add a new "debug" job mode, that is propagated to unit_start() and for
662 services results in two things: we raise SIGSTOP right before invoking
663 execve() and turn off watchdog support. Then, use that to implement
664 "systemd-gdb" for attaching to the start-up of any system service in its
667 * gpt-auto logic: related to the above, maybe support a "secondary" root
668 partition, that is mounted to / and is writable, and where the actual root's
669 /usr is mounted into.
671 * 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
673 * drop nss-myhostname in favour of nss-resolve?
675 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
676 then use that for the setting used in user@.service. It should be understood
677 relative to the configured default value.
679 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
681 * enable LockMLOCK to take a percentage value relative to physical memory
683 * Permit masking specific netlink APIs with RestrictAddressFamily=
685 * nspawn: support that /proc, /sys/, /dev are pre-mounted
687 * define gpt header bits to select volatility mode
689 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
691 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
693 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
695 * ProtectKeyRing= to take keyring calls away
697 * RemoveKeyRing= to remove all keyring entries of the specified user
699 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
700 on PID 1 with the relevant signals, and makes relevant files in /sys and
701 /proc (such as the sysrq stuff) unavailable
703 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
705 * journalctl: make sure -f ends when the container indicated by -M terminates
707 * mount: automatically search for "main" partition of an image has multiple
710 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
711 find a way to map the User=/Group= of the service to the right name. This way
712 a user/group for a service only has to exist on the host for the right
715 * add bus API for creating unit files in /etc, reusing the code for transient units
717 * add bus API to remove unit files from /etc
719 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
721 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
722 kernel doesn't support linkat() that replaces existing files, currently)
724 * transient units: don't bother with actually setting unit properties, we
725 reload the unit file anyway
727 * journald: sigbus API via a signal-handler safe function that people may call
728 from the SIGBUS handler
730 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
732 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
733 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
735 * cache sd_event_now() result from before the first iteration...
737 * PID1: find a way how we can reload unit file configuration for
738 specific units only, without reloading the whole of systemd
740 * add an explicit parser for LimitRTPRIO= that verifies
741 the specified range and generates sane error messages for incorrect
744 * when we detect that there are waiting jobs but no running jobs, do something
746 * push CPUAffinity= also into the "cpuset" cgroup controller
748 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
750 * there's probably something wrong with having user mounts below /sys,
751 as we have for debugfs. for example, src/core/mount.c handles mounts
752 prefixed with /sys generally special.
753 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
755 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
757 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
759 * add a job mode that will fail if a transaction would mean stopping
760 running units. Use this in timedated to manage the NTP service
762 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
764 * The udev blkid built-in should expose a property that reflects
765 whether media was sensed in USB CF/SD card readers. This should then
766 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
767 picked up by systemd unless they contain a medium. This would mirror
768 the behaviour we already have for CD drives.
770 * networkd/udev: implement SR_IOV configuration in .link files:
771 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
773 * hostnamectl: show root image uuid
775 * Find a solution for SMACK capabilities stuff:
776 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
778 * "systemctl preset-all" should probably order the unit files it
779 operates on lexicographically before starting to work, in order to
780 ensure deterministic behaviour if two unit files conflict (like DMs
783 * synchronize console access with BSD locks:
784 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
786 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
787 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
789 * figure out when we can use the coarse timers
791 * add "systemctl start -v foobar.service" that shows logs of a service
792 while the start command runs. This is non-trivial to do without
793 races though, since we should flush out all journal messages before
794 returning from the "systemctl stop".
796 * 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
798 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
800 * maybe allow timer units with an empty Units= setting, so that they
801 can be used for resuming the system but nothing else.
803 * what to do about udev db binary stability for apps? (raw access is not an option)
805 * systemctl: if some operation fails, show log output?
807 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
808 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
810 * exponential backoff in timesyncd when we cannot reach a server
812 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
814 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
816 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
817 (throughout the codebase, not only PID1)
821 - service registration
822 - service/domain/types browsing
824 - DNS-SD service registration from socket units
825 - resolved should optionally register additional per-interface LLMNR
826 names, so that for the container case we can establish the same name
827 (maybe "host") for referencing the server, everywhere.
828 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
829 - hook up resolved with machined-based address resolution
831 * refcounting in sd-resolve is borked
833 * Add a new verb "systemctl top"
835 * add new gpt type for btrfs volumes
837 * support empty /etc boots nicely:
838 - nspawn/gpt-generator: introduce new gpt partition type for /usr
840 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
842 * a way for container managers to turn off getty starting via $container_headless= or so...
844 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
846 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
847 they run added to the initial transaction and thus confuse Type=idle.
849 * add bus api to query unit file's X fields.
851 * gpt-auto-generator:
852 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
853 - Make /home automount rather than mount?
855 * add generator that pulls in systemd-network from containers when
856 CAP_NET_ADMIN is set, more than the loopback device is defined, even
857 when it is otherwise off
859 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
861 * implement Distribute= in socket units to allow running multiple
862 service instances processing the listening socket, and open this up
865 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
866 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
867 should SIGSTOP all unit processes in a loop until all processes of
868 it are fully stopped. This can later be used for app management by
869 desktop UIs such as gnome-shell to freeze apps that are not visible
870 on screen, not unlike how job control works on the shell
873 - implement per-slice CPUFairScheduling=1 switch
874 - introduce high-level settings for RT budget, swappiness
875 - how to reset dynamically changed unit cgroup attributes sanely?
876 - when reloading configuration, apply new cgroup configuration
877 - when recursively showing the cgroup hierarchy, optionally also show
878 the hierarchies of child processes
881 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
883 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
885 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
887 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
889 * 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
891 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
893 * If we try to find a unit via a dangling symlink, generate a clean
894 error. Currently, we just ignore it and read the unit from the search
897 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
899 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
901 * load .d/*.conf dropins for device units
905 - GetAllProperties() on a non-existing object does not result in a failure currently
906 - port to sd-resolve for connecting to TCP dbus servers
907 - 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
908 - see if we can drop more message validation on the sending side
909 - add API to clone sd_bus_message objects
910 - longer term: priority inheritance
912 - NameLost/NameAcquired obsolete
915 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
918 - allow multiple signal handlers per signal?
919 - document chaining of signal handler for SIGCHLD and child handlers
920 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
921 - maybe support iouring as backend, so that we allow hooking read and write
922 operations instead of IO ready events into event loops. See considerations
924 http://blog.vmsplice.net/2020/07/rethinking-event-loop-integration-for.html
926 * investigate endianness issues of UUID vs. GUID
928 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
929 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
931 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
933 * add a pam module that on password changes updates any LUKS slot where the password matches
936 - add unit tests for config_parse_device_allow()
938 * seems that when we follow symlinks to units we prefer the symlink
939 destination path over /etc and /usr. We should not do that. Instead
940 /etc should always override /run+/usr and also any symlink
943 * when isolating, try to figure out a way how we implicitly can order
944 all units we stop before the isolating unit...
946 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
948 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
949 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
950 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
952 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
953 that the boot loader should be installed to the ESP. Define a way
954 how an installer can figure out whether a BLS compliant boot loader
957 * think about requeuing jobs when daemon-reload is issued? usecase:
958 the initrd issues a reload after fstab from the host is accessible
959 and we might want to requeue the mounts local-fs acquired through
962 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
964 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
966 * shutdown logging: store to EFI var, and store to USB stick?
968 * merge unit_kill_common() and unit_kill_context()
971 - honor language efi variables for default language selection (if there are any?)
972 - honor timezone efi variables for default timezone selection (if there are any?)
973 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
975 - recognize the case when not booted on EFI
977 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
979 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
981 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
984 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
985 - logind: wakelock/opportunistic suspend support
986 - Add pretty name for seats in logind
987 - logind: allow showing logout dialog from system?
988 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
989 - if pam_systemd is invoked by su from a process that is outside of a
990 any session we should probably just become a NOP, since that's
991 usually not a real user session but just some system code that just
993 - logind: make the Suspend()/Hibernate() bus calls wait for the for
994 the job to be completed. before returning, so that clients can wait
995 for "systemctl suspend" to finish to know when the suspending is
997 - logind: when the power button is pressed short, just popup a
998 logout dialog. If it is pressed for 1s, do the usual
999 shutdown. Inspiration are Macs here.
1000 - expose "Locked" property on logind sesison objects
1001 - maybe allow configuration of the StopTimeout for session scopes
1002 - rename session scope so that it includes the UID. THat way
1003 the session scope can be arranged freely in slices and we don't have
1004 make assumptions about their slice anymore.
1005 - follow PropertiesChanged state more closely, to deal with quick logouts and
1007 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
1010 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
1011 - journald: also get thread ID from client, plus thread name
1012 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
1013 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
1014 - fall back to /dev/log based logging in libsystemd-journal, if we cannot log natively?
1015 - declare the local journal protocol stable in the wiki interface chart
1016 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
1017 - journald: when dropping msgs due to ratelimit make sure to write
1018 "dropped %u messages" not only when we are about to print the next
1019 message that works, but already after a short timeout
1020 - check if we can make journalctl by default use --follow mode inside of less if called without args?
1021 - maybe add API to send pairs of iovecs via sd_journal_send
1022 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
1023 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
1024 and !FOOBAR for events without FOOBAR.
1025 - journal: store timestamp of journal_file_set_offline() in the header,
1026 so it is possible to display when the file was last synced.
1027 - 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.
1028 - journal: find a way to allow dropping history early, based on priority, other rules
1029 - journal: When used on NFS, check payload hashes
1030 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
1031 - refuse taking lower-case variable names in sd_journal_send() and friends.
1032 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
1033 - journal: deal nicely with byte-by-byte copied files, especially regards header
1034 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
1035 - Replace utmp, wtmp, btmp, and lastlog completely with journal
1036 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
1037 - when a kernel driver logs in a tight loop, we should ratelimit that too.
1038 - journald: optionally, log debug messages to /run but everything else to /var
1039 - journald: when we drop syslog messages because the syslog socket is
1040 full, make sure to write how many messages are lost as first thing
1041 to syslog when it works again.
1042 - journald: allow per-priority and per-service retention times when rotating/vacuuming
1043 - journald: make use of uid-range.h to managed uid ranges to split
1045 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
1046 - improve journalctl performance by loading journal files
1047 lazily. Encode just enough information in the file name, so that we
1048 do not have to open it to know that it is not interesting for us, for
1049 the most common operations.
1050 - man: document that corrupted journal files is nothing to act on
1051 - rework journald sigbus stuff to use mutex
1052 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
1053 services that run under their own user ids, and use User= (but only
1054 in a world where userns is ubiquitous since otherwise we cannot
1055 invoke those daemons on the host AND in a container anymore). Also,
1056 if LimitNPROC= is used without User= we should warn and refuse
1058 - journalctl --verify: don't show files that are currently being
1059 written to as FAIL, but instead show that their are being written to.
1060 - add journalctl -H that talks via ssh to a remote peer and passes through
1062 - add a version of --merge which also merges /var/log/journal/remote
1063 - journalctl: -m should access container journals directly by enumerating
1064 them via machined, and also watch containers coming and going.
1065 Benefit: nspawn --ephemeral would start working nicely with the journal.
1066 - assign MESSAGE_ID to log messages about failed services
1067 - check if loop in decompress_blob_xz() is necessary
1069 * add a test if all entries in the catalog are properly formatted.
1070 (Adding dashes in a catalog entry currently results in the catalog entry
1071 being silently skipped. journalctl --update-catalog must warn about this,
1072 and we should also have a unit test to check that all our message are OK.)
1075 - document that deps in [Unit] sections ignore Alias= fields in
1076 [Install] units of other units, unless those units are disabled
1077 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
1078 - document that service reload may be implemented as service reexec
1079 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1080 - document systemd-journal-flush.service properly
1081 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1082 - man: document the very specific env the shutdown drop-in tools live in
1083 - man: add more examples to man pages,
1084 - in particular an example how to do the equivalent of switching runlevels
1085 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
1086 - document root=gpt-auto properly
1089 - add systemctl switch to dump transaction without executing it
1090 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1091 - "systemctl disable" on a static unit prints no message and does
1092 nothing. "systemctl enable" does nothing, and gives a bad message
1093 about it. Should fix both to print nice actionable messages.
1094 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1095 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1096 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1097 - systemctl: "Journal has been rotated since unit was started." message is misleading
1098 - systemctl status output should include list of triggering units and their status
1101 - "systemctl mask" should find all names by which a unit is accessible
1102 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1105 - timer units should get the ability to trigger when:
1107 - Modulate timer frequency based on battery state
1109 * add libsystemd-password or so to query passwords during boot using the password agent logic
1111 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1113 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1115 * make repeated alt-ctrl-del presses printing a dump
1117 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1119 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1122 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1123 with seccomp. That should provide us with a useful log buffer that
1124 systemd can log to during early boot, and disconnect container logs
1125 from the kernel's logs.
1126 - as soon as networkd has a bus interface, hook up --network-interface=,
1127 --network-bridge= with networkd, to trigger netdev creation should an
1128 interface be missing
1129 - a nice way to boot up without machine id set, so that it is set at boot
1130 automatically for supporting --ephemeral. Maybe hash the host machine id
1131 together with the machine name to generate the machine id for the container
1132 - fix logic always print a final newline on output.
1133 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1134 - should optionally support receiving WATCHDOG=1 messages from its payload
1136 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1137 running, remove them when shut down.
1140 - add an API so that libvirt-lxc can inform us about network interfaces being
1141 removed or added to an existing machine
1142 - "machinectl migrate" or similar to copy a container from or to a
1143 difference host, via ssh
1144 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1145 "machinectl start" with a new --ephemeral switch
1146 - "machinectl status" should also show internal logs of the container in
1148 - "machinectl history"
1150 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1151 shell in it, and marks it read-only after use
1154 - cryptsetup-generator: allow specification of passwords in crypttab itself
1155 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1157 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1158 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1160 * add a dependency on standard-conf.xml and other included files to man pages
1162 * MountFlags=shared acts as MountFlags=slave right now.
1164 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1166 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1171 - add trigger --subsystem-match=usb/usb_device device
1172 - reimport udev db after MOVE events for devices without dev_t
1174 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1176 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1179 - save coredump in Windows/Mozilla minidump format
1180 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1182 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1184 * be able to specify a forced restart of service A where service B depends on, in case B
1185 needs to be auto-respawned?
1188 - apply "x" on "D" too (see patch from William Douglas)
1189 - instead of ignoring unknown fields, reject them.
1190 - creating new directories/subvolumes/fifos/device nodes
1191 should not follow symlinks. None of the other adjustment or creation
1192 calls follow symlinks.
1194 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1196 * verify that the AF_UNIX sockets of a service in the fs still exist
1197 when we start a service in order to avoid confusion when a user
1198 assumes starting a service is enough to make it accessible
1200 * Make it possible to set the keymap independently from the font on
1201 the kernel cmdline. Right now setting one resets also the other.
1203 * and a dbus call to generate target from current state
1205 * write blog stories about:
1206 - hwdb: what belongs into it, lsusb
1207 - enabling dbus services
1208 - how to make changes to sysctl and sysfs attributes
1210 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1211 - testing with Harald's awesome test kit
1213 - how to develop against journal browsing APIs
1214 - the journal HTTP iface
1215 - non-cgroup resource management
1216 - dynamic resource management with cgroups
1217 - refreshed, longer missions statement
1218 - calendar time events
1219 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1220 - how to create your own target
1221 - instantiated apache, dovecot and so on
1222 - hooking a script into various stages of shutdown/rearly booot
1224 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1226 * dot output for --test showing the 'initial transaction'
1229 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1230 log both units as UNIT=, so that journalctl -u triggers on both.
1231 - generate better errors when people try to set transient properties
1232 that are not supported...
1233 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1234 - maybe introduce WantsMountsFor=? Usecase:
1235 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1236 - recreate systemd's D-Bus private socket file on SIGUSR2
1237 - move PAM code into its own binary
1238 - when we automatically restart a service, ensure we restart its rdeps, too.
1239 - hide PAM options in fragment parser when compile time disabled
1240 - Support --test based on current system state
1241 - 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().
1242 - after deserializing sockets in socket.c we should reapply sockopts and things
1243 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1244 currently is properly synchronous, Reexec() is weird, because we
1245 cannot delay the response properly until we are back, so instead of
1246 being properly synchronous we just keep open the fd and close it
1247 when done. That means clients do not get a successful method reply,
1248 but much rather a disconnect on success.
1249 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1250 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1253 - allow port=0 in .socket units
1254 - maybe introduce ExecRestartPre=
1255 - add ReloadSignal= for configuring a reload signal to use
1256 - implement Register= switch in .socket units to enable registration
1257 in Avahi, RPC and other socket registration services.
1258 - allow Type=simple with PIDFile=
1259 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1260 - allow writing multiple conditions in unit files on one line
1261 - introduce Type=pid-file
1262 - introduce mix of BindTo and Requisite
1263 - add a concept of RemainAfterExit= to scope units
1264 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1265 - add verification of [Install] section to systemd-analyze verify
1268 - Make sure ID_PATH is always exported and complete for
1269 network devices where possible, so we can safely rely
1273 - add support for more attribute types
1274 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1277 - add more keys to [Route] and [Address] sections
1278 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1279 - add reduced [Link] support to .network files
1280 - properly handle routerless dhcp leases
1281 - work with non-Ethernet devices
1282 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1283 - the DHCP lease data (such as NTP/DNS) is still made available when
1284 a carrier is lost on a link. It should be removed instantly.
1285 - expose in the API the following bits:
1286 - option 15, domain name
1287 - option 12, hostname and/or option 81, fqdn
1288 - option 123, 144, geolocation
1289 - option 252, configure http proxy (PAC/wpad)
1290 - provide a way to define a per-network interface default metric value
1291 for all routes to it. possibly a second default for DHCP routes.
1292 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1293 support Name=foo*|bar*|baz ?
1294 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1295 - whenever uplink info changes, make DHCP server send out FORCERENEW
1297 * Figure out how to do unittests of networkd's state serialization
1300 - figure out how much we can increase Maximum Message Size
1303 - add functions to set previously stored IPv6 addresses on startup and get
1304 them at shutdown; store them in client->ia_na
1305 - write more test cases
1306 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1307 - implement support for temporary adressess (IA_TA)
1308 - implement dhcpv6 authentication
1309 - investigate the usefulness of Confirm messages; i.e. are there any
1310 situations where the link changes without any loss in carrier detection
1312 - some servers don't do rapid commit without a filled in IA_NA, verify
1319 - natively watch for dbus-*.service symlinks (PENDING)
1320 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1322 * make cryptsetup lower --iter-time
1324 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1326 * /usr/bin/service should actually show the new command line
1328 * 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=
1330 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1332 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1334 * register catalog database signature as file magic
1336 * zsh shell completion:
1337 - <command> <verb> -<TAB> should complete options, but currently does not
1338 - systemctl add-wants,add-requires
1340 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1341 * If timer has just OnInactiveSec=..., it should fire after a specified time
1342 after being started.
1346 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1348 * check for strerror(r) instead of strerror(-r)
1352 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1354 * use secure_getenv() instead of getenv() where appropriate
1356 * link up selected blog stories from man pages and unit files Documentation= fields
1357 String is not UTF-8 clean, ignoring assignment
