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 * userdbctl: "Password OK: yes" is shown even when there are no passwords
8 or the password is locked.
12 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
16 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
18 * rework mount.c and swap.c to follow proper state enumeration/deserialization
19 semantics, like we do for device.c now
23 * add wrapper for mount() that uses O_PATH on the destination and than mounts
24 to /proc/self/fd/xxx so that we basically have a mount() with O_NOFOLLOW like
25 behaviour. (in case of bind mounts do it on both source and target)
27 * add root=tmpfs that mounts a tmpfs to /sysroot (to be used in combination
28 with usr=…, for a similar effect as systemd.volatile=yes but without the
29 "hide-out" effect). Also, add root=gpt-auto-late support or so, that is like
30 root=gpt-auto but initially mounts a tmpfs to /sysroot, and then revisits
31 later after systemd-repart ran. Usecase: let's ship images with only /usr
32 partition, then on first boot create the root partition. In this case we want
33 to read the repart data from /usr before the root partition exists. Add
34 usr=gpt-auto that automatically finds a /usr partition.
36 * homed: keep an fd to the homedir open at all times, to keep the fs pinned
37 (autofs and such) while user is loged in.
39 * nss-systemd: also synthesize shadow records for users/groups
41 * make use of new glibc 2.32 APIs sigabbrev_np() and strerrorname_np().
43 * cryptsetup: if keyfile specified in crypttab is AF_UNIX socket, connect to it
44 and read from it (like we do elsewhere with READ_FULL_FILE_CONNECT_SOCKET)
46 * when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or
47 so, freeze the payload too.
49 * repart: support setting up dm-integrity with HMAC
51 * add /etc/integritytab, to support dm-integrity setups. In particular those
52 with HMAC as hash function, so that we can have a protected /home without
53 encryption (leaving encryption to the individual dirs/homed).
55 * complement root=, rootflags=, rootfstype= with rootsubdir= which allows
56 mounting a subdir of the root fs as actual root. This can be used as
57 fstype-agnostic version of btrfs' rootflags=subvol=foobar.
59 * Support ProtectProc= or so, using: https://patchwork.kernel.org/cover/11310197/
61 * if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
63 * build short web pages out of each catalog entry, build them along with man
64 pages, and include hyperlinks to them in the journal output
66 * machined: add API to acquire UID range. add API to mount/dissect loopback
67 file. Both protected by PK. Then make nspawn use these APIs to run
68 unprivileged containers. i.e. push the truly privileged bits into machined,
69 so that the client side can remain entirely unprivileged, with SUID or
72 * journald: do journal file writing out-of-process, with one writer process per
73 client UID, so that synthetic hash table collisions can slow down a specific
74 user's journal stream down but not the others.
76 * add "throttling" to sd-event event sources: optionally, when we wake up too
77 often for one, let's turn it off entirely for a while. Use that for the
78 /proc/self/mountinfo logic.
80 * nspawn: support time namespaces
82 * systemd-firstboot: make sure to always use chase_symlinks() before
85 * add ConditionSecurity=tpm2
87 * Remove any support for booting without /usr pre-mounted in the initrd entirely.
88 Update INITRD_INTERFACE.md accordingly.
90 * pid1: Move to tracking of main pid/control pid of units per pidfd
92 * pid1: support new clone3() fork-into-cgroup feature
94 * pid1: also remove PID files of a service when the service starts, not just
97 * make us use dynamically fewer deps for containers in general purpose distros:
98 o turn into dlopen() deps:
101 - p11-kit-trust (always)
102 - kmod-libs (only when called from PID 1)
103 - libblkid (only in RootImage= handling in PID 1, but not elsewhere)
104 - libpam (only when called from PID 1)
105 - bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are,
106 since they are so basic and our defaults)
107 o move into separate libsystemd-shared-iptables.so .so
108 - iptables-libs (only used by nspawn + networkd)
110 * seccomp: when SystemCallArchitectures=native is set then don't install any
111 other seccomp filters for any of the other archs, in order to reduce the
112 number of seccomp filters we install needlessly.
114 * seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can.
115 Apparently kernel performance is much better with fewer larger seccomp
116 filters than with more smaller seccomp filters.
118 * systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
119 mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
121 * All tools that support --root= should also learn --image= so that they can
122 operate on disk images directly. Specifically: bootctl, systemctl,
123 coredumpctl. (Already done: systemd-nspawn, systemd-firstboot,
124 systemd-repart, systemd-tmpfiles, systemd-sysusers, journalctl)
126 * seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out
128 * seccomp: don't install filters for ABIs that are masked anyway for the
131 * seccomp: maybe merge all filters we install into one with that libseccomp API that allows merging.
133 * credentials system:
134 - maybe add AcquireCredential= for querying a cred via ask-password
135 - maybe try to acquire creds via keyring?
136 - maybe try to pass creds via keyring?
137 - maybe optionally pass creds via memfd
138 - maybe add support for decrypting creds via TPM
139 - maybe add support for decrypting/importing creds via pkcs11
140 - make systemd-cryptsetup acquire pw via creds logic
141 - make PAMName= acquire pw via creds logic
142 - make macsec/wireguard code in networkd read key via creds logic
143 - make gatwayd/remote read key via creds logic
144 - add sd_notify() command for flushing out creds not needed anymore
146 * homed: during login resize fs automatically towards size goal. Specifically,
147 resize to diskSize if possible, but leave a certain amount (configured by a
148 new value diskLeaveFreeSize) of space free on the backing fs.
150 * homed: permit multiple user record signing keys to be used locally, and pick
151 the right one for signing records automatically depending on a pre-existing
154 * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
155 and insert a local signature instead.
157 * homed: as an extension to the directory+subvolume backend: if located on
158 especially marked fs, then sync down password into LUKS header of that fs,
159 and always verify passwords against it too. Bootstrapping is a problem
160 though: if no one is logged in (or no other user even exists yet), how do you
161 unlock the volume in order to create the first user and add the first pw.
163 * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
165 * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
168 * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
171 * when systemd-nspawn and suchlike dissect an OS image, and there are multiple
172 root partitions, do an strverscmp() on the partition label and boot
173 first. That is inspired how sd-boot figures out which kernel to boot, and
174 thus allows defining OS images which can be A/B updated and we default to the
175 newest version automatically, both in nspawn and in sd-boot
177 * cryptsetup: support FIDO2 tokens for deriving keys (i.e. do what homed can do
178 also in plain cryptsetup)
180 * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
184 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
185 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
186 - make it operate on loopback files, dissecting enough to find ESP to operate on
188 * Maybe add a separate GPT partition type to the discoverable partition spec
189 for "hibernate" partitions, that are exactly like swap partitions but only
190 activated right before hibernation and thus never used for regular swapping.
192 * by default, in systemd --user service bump the OOMAdjust to 100, as privs
193 allow so that systemd survives
195 * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
196 "base64:" prefix. Useful in particular for pkcs11 mode.
198 * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
199 systemd-makefs.service instead.
201 * socket units: allow creating a udev monitor socket with ListenDevices= or so,
202 with matches, then activate app through that passing socket over
204 * unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
206 - port sd_id128_get_machine_app_specific() over from khash
207 - port resolved over from libgcrypt (DNSSEC code)
208 - port journald + fsprg over from libgcrypt
209 - port importd over from libgcrypt
210 - when that's done: kill khash.c
211 - when that's done: kill gnutls support in resolved
213 * kill zenata, all hail weblate?
215 * when we resize disks (homed?) always round up to 4K sectors, not 512K
217 * add growvol and makevol options for /etc/crypttab, similar to
218 x-systemd.growfs and x-systemd-makefs.
220 * hook up the TPM to /etc/crypttab, with a new option that is similar to the
221 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
222 unsealed from the TPM. Optionally, if TPM is not available fall back to
223 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
224 that the device paths stay the same, regardless if crypto is used or not.
226 * systemd-repart: by default generate minimized partition tables (i.e. tables
227 that only cover the space actually used, excluding any free space at the
228 end), in order to maximize dd'ability. Requires libfdisk work, see
229 https://github.com/karelzak/util-linux/issues/907
231 * systemd-repart: MBR partition table support. Care needs to be taken regarding
232 Type=, so that partition definitions can sanely apply to both the GPT and the
233 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
234 for the two partition types explicitly. And provide an internal mapping so
235 that "Type=linux-generic" maps to the right types for both partition tables
238 * systemd-repart: allow sizing partitions as factor of available RAM, so that
239 we can reasonably size swap partitions for hibernation.
241 * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
243 * systemd-repart: allow boolean option that ensures that if existing partition
244 doesn't exist within the configured size bounds the whole command fails. This
245 is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
246 of repart files for the case where ESP is large enough and one where it isn't
247 and XBOOTLDR is added in instead. Then apply the former first, and if it
248 fails to apply use the latter.
250 * systemd-repart: add per-partition option to never reuse existing partition
251 and always create anew even if matching partition already exists.
253 * systemd-repart: add per-partition option to fail if partition already exist,
254 i.e. is not added new. Similar, add option to fail if partition does not exist yet.
256 * systemd-repart: allow disabling growing of specific partitions, or making
257 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
259 * systemd-repart: make it a static checker during early boot for existence and
260 absence of other partitions for trusted boot environments
262 * userdb: allow username prefix searches in varlink API, allow realname and
263 realname substr searches in varlink API
265 * userdb: allow uid/gid range checks
267 * userdb: allow existence checks
269 * pid1: activation by journal search expression
271 * when switching root from initrd to host, set the machine_id env var so that
272 if the host has no machine ID set yet we continue to use the random one the
275 * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
276 it fo reaping assigned but unknown children. This needs to some special care
277 to operate somewhat sensibly in light of priorities: P_ALL will return
278 arbitrary processes, regardless of the priority we want to watch them with,
279 hence on each event loop iteration check all processes which we shall watch
280 with higher prio explicitly, and then watch the entire rest with P_ALL.
282 * tweak sd-event's child watching: keep a prioq of children to watch and use
283 waitid() only on the children with the highest priority until one is waitable
284 and ignore all lower-prio ones from that point on
286 * maybe introduce xattrs that can be set on the root dir of the root fs
287 partition that declare the volatility mode to use the image in. Previously I
288 thought marking this via GPT partition flags but that's not ideal since
289 that's outside of the LUKS encryption/verity verification, and we probably
290 shouldn't operate in a volatile mode unless we got told so from a trusted
293 * figure out automatic partition discovery when combining writable root dir
296 * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
297 may be used to mark a whole binary as non-coredumpable. Would fix:
298 https://bugs.freedesktop.org/show_bug.cgi?id=69447
300 * teach parse_timestamp() timezones like the calendar spec already knows it
302 * beef up hibernation to optionally do swapon/swapoff immediately before/after
305 * beef up s2h to implement a battery watch loop: instead of entering
306 hibernation unconditionally after coming back from resume make a decision
307 based on the battery load level: if battery level is above a specific
308 threshold, go to suspend again, only hibernate if below it. This means we'd
309 stick to suspend usually, but fall back to hibernation only when battery runs
310 empty (well, subject to our sampling interval). Related to this, check if we
311 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
312 i.e. see if it can wake up machines from suspend, so that we could resume
313 automatically when the system is low on power and move automatically to
314 hibernation mode. (see
315 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
317 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
320 * add an explicit "vertical" mode to format-table, so that "systemctl
321 status"-like outputs (i.e. with a series of field names left and values
322 right) become genuine first class citizens, and we gain automatic, sane JSON
325 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
326 that are linked to these places instead of copied. After all they are
327 constant vendor data.
329 * maybe add kernel cmdline params: to force random seed crediting
331 * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
332 so that we make cgroup agent logic safe
334 * nspawn/machined: add API to invoke binary in container, then use that as
335 fallback in "machinectl shell"
337 * logind: rework pam_logind to also do a bus call in case of invocation from
338 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
339 behaviour selectable via pam module option.
342 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
343 - rollback when resize fails mid-operation
344 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
346 - shrink fs on logout?
347 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
348 - create on activate?
349 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
350 - communicate clearly when usb stick is safe to remove. probably involves
351 beefing up logind to make pam session close hook synchronous and wait until
352 systemd --user is shut down.
353 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
354 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk
355 images (and btrfs snapshots of subvolumes) (think: time machine)
356 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
357 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
358 - fingerprint authentication, pattern authentication, …
359 - make sure "classic" user records can also be managed by homed
360 - make size of $XDG_RUNTIME_DIR configurable in user record
361 - query password from kernel keyring first
362 - update even if record is "absent"
363 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
364 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
365 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
366 - make slice for users configurable (requires logind rework)
367 - logind: populate auto-login list bus property from PKCS#11 token
368 - when determining state of a LUKS home directory, check DM suspended sysfs file
369 - introduce API for "making room", that grows/shrinks home directory
370 according to elastic parameters, discards blocks, and removes additional snapshots. Call it
371 either from UI when disk space gets low
373 * introduce a new per-process uuid, similar to the boot id, the machine id, the
374 invocation id, that is derived from process creds, specifically a hashed
375 combination of AT_RANDOM + getpid() + the starttime from
376 /proc/self/status. Then add these ids implicitly when logging. Deriving this
377 uuid from these three things has the benefit that it can be derived easily
378 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
381 * let's not GC a unit while its ratelimits are still pending
383 * when killing due to service watchdog timeout maybe detect whether target
384 process is under ptracing and then log loudly and continue instead.
386 * introduce a new group to own TPM devices
388 * make rfkill uaccess controllable by default, i.e. steal rule from
389 gnome-bluetooth and friends
391 * tweak journald context caching. In addition to caching per-process attributes
392 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
393 keyed by cgroup path, and guarded by ctime changes. This should provide us
394 with a nice speed-up on services that have many processes running in the same
397 * make MAINPID= message reception checks even stricter: if service uses User=,
398 then check sending UID and ignore message if it doesn't match the user or
401 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
404 * when importing an fs tree with machined, optionally apply userns-rec-chown
406 * when importing an fs tree with machined, complain if image is not an OS
408 * Maybe introduce a helper safe_exec() or so, which is to execve() which
409 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
410 to 1K implicitly, unless explicitly opted-out.
412 * rework seccomp/nnp logic that even if User= is used in combination with
413 a seccomp option we don't have to set NNP. For that, change uid first whil
414 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
416 * add a concept for automatically loading per-unit secrets off disk and
417 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
418 ConfigurationDirectory=.
420 * when no locale is configured, default to UEFI's PlatformLang variable
422 * bootctl,sd-boot: actually honour the "architecture" key
424 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
425 usefaultd() and make systemd-analyze check for it.
427 * paranoia: whenever we process passwords, call mlock() on the memory
428 first. i.e. look for all places we use free_and_erasep() and
429 augment them with mlock(). Also use MADV_DONTDUMP.
431 * Move RestrictAddressFamily= to the new cgroup create socket
433 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
436 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
437 log.c and sd-journal-send
439 * optionally: turn on cgroup delegation for per-session scope units
441 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
443 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
444 can add in file system drivers and such
446 * sd-boot: optionally, show boot menu when previous default boot item has
447 non-zero "tries done" count
449 * introduce an option (or replacement) for "systemctl show" that outputs all
450 properties as JSON, similar to busctl's new JSON output. In contrast to that
451 it should skip the variant type string though.
453 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
454 contains some identifier for the project, which allows us to include
455 clickable links to source files generating these log messages. The identifier
456 could be some abberviated URL prefix or so (taking inspiration from Go
457 imports). For example, for systemd we could use
458 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
459 sufficient to build a link by prefixing "http://" and suffixing the
462 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
463 make clickable links from log messages carrying a MESSAGE_ID, that lead to
464 some explanatory text online.
466 * maybe extend .path units to expose fanotify() per-mount change events
468 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
469 output of "systemctl list-units" slightly by showing the tree structure of
470 the slices, and the units attached to them.
472 * the a-posteriori stopping of units bound to units that disappeared logic
473 should be reworked: there should be a queue of units, and we should only
474 enqueue stop jobs from a defer event that processes queue instead of
475 right-away when we find a unit that is bound to one that doesn't exist
476 anymore. (similar to how the stop-unneeded queue has been reworked the same
479 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
480 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
481 for hangup or ^D before passing on the EOF.
483 * When reloading configuration PID 1 should reset all its properties to the
484 original defaults before calling parse_config()
486 * nspawn: greater control over selinux label?
488 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
491 1. add resume_offset support to the resume code (i.e. support swap files
493 2. check if swap is on weird storage and refuse if so
494 3. add auto-detection of hibernation images
496 * cgroups: use inotify to get notified when somebody else modifies cgroups
497 owned by us, then log a friendly warning.
499 * beef up log.c with support for stripping ANSI sequences from strings, so that
500 it is OK to include them in log strings. This would be particularly useful so
501 that our log messages could contain clickable links for example for unit
502 files and suchlike we operate on.
504 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
506 * add attach --enable and attach --now (for attach+enable+start)
508 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
509 selected user is resolvable in the service even if it ships its own /etc/passwd)
511 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
512 other doesn't. What a disaster. Probably to exclude it. Also
513 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
516 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
517 usually IN_ATTRIB is the right way to watch deleted files, as the former only
518 fires when a file is actually removed from disk, i.e. the link count drops to
519 zero and is not open anymore, while the latter happens when a file is
520 unlinked from any dir.
522 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
524 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
526 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
528 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
529 files and directories that are left writable for a unit, and which are
530 removed after the unit goes down again. A bit like --ephemeral for
531 systemd-nspawn but for system services. If used together with RootImage= this
532 should reflink the image file itself.
534 Related: add Ephemeral=<path1> <path2> … which would allow marking
535 specific paths only like this.
537 * add CopyFile= or so as unit file setting that may be used to copy files or
538 directory trees from the host to the services RootImage= and RootDirectory=
539 environment. Which we can use for /etc/machine-id and in particular
540 /etc/resolv.conf. Should be smart and do something useful on read-only
541 images, for example fall back to read-only bind mounting the file instead.
543 * show invocation ID in systemd-run output
545 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
547 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
548 and so on, which would mean we could report errors and such.
550 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
553 * introduce DefaultSlice= or so in system.conf that allows changing where we
554 place our units by default, i.e. change system.slice to something
555 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
556 be moved somewhere else too. Finally machined and logind should get similar
557 options so that it is possible to move user session scopes and machines to a
558 different slice too by default. Usecase: people who want to put resources on
559 the entire system, with the exception of one specific service. See:
560 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
562 * maybe rework get_user_creds() to query the user database if $SHELL is used
563 for root, but only then.
565 * be stricter with fds we receive for the fdstore: close them asynchronously
567 * calenderspec: add support for week numbers and day numbers within a
568 year. This would allow us to define "bi-weekly" triggers safely.
570 * sd-bus: add vtable flag, that may be used to request client creds implicitly
571 and asynchronously before dispatching the operation
573 * sd-bus: parse addresses given in sd_bus_set_addresses immediately and not
574 only when used. Add unit tests.
576 * make use of ethtool veth peer info in machined, for automatically finding out
577 host-side interface pointing to the container.
579 * add some special mode to LogsDirectory=/StateDirectory=… that allows
580 declaring these directories without necessarily pulling in deps for them, or
581 creating them when starting up. That way, we could declare that
582 systemd-journald writes to /var/log/journal, which could be useful when we
583 doing disk usage calculations and so on.
585 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
587 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
589 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
590 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
591 as the unit is running or has a job queued.
593 * support projid-based quota in machinectl for containers
595 * add a way to lock down cgroup migration: a boolean, which when set for a unit
596 makes sure the processes in it can never migrate out of it
598 * blog about fd store and restartable services
600 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
602 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
603 magic meaning and is no longer upgraded to something else if set explicitly.
605 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
606 make it lose its identity, i.e. be anonymous. For this we'd have to patch
607 through the whole tree to make all code deal with the case where no machine
610 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
611 suitable for processing with rrdtool. Add bus API to access this data, and
612 possibly implement a CPULoad property based on it.
614 * beef up pam_systemd to take unit file settings such as cgroups properties as
617 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
618 the quota of a the user indicated in User= via unit file settings, like the
619 other resource management concepts. Would mix nicely with DynamicUser=1. Or
620 alternatively, do this with projids, so that we can also cover services
621 running as root. Quota should probably cover all the special dirs such as
622 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
623 is set, plus the whole disk space any image configured with RootImage=.
625 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
626 disks to see if the UID is already in use.
628 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
629 for all units. It should be both a way to pin units into memory as well as a
630 wait to retrieve their exit data.
632 * expose IO accounting data on the bus, show it in systemd-run --wait and log
633 about it in the resource log message
635 * show whether a service has out-of-date configuration in "systemctl status" by
636 using mtime data of ConfigurationDirectory=.
638 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
639 creates a static, persistent user rather than a dynamic, transient user. We
640 can leverage code from sysusers.d for this.
642 * add some optional flag to ReadWritePaths= and friends, that has the effect
643 that we create the dir in question when the service is started. Example:
645 ReadWritePaths=:/var/lib/foobar
647 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
648 the sd-journal logging socket, and, if the timeout is set to 0, sets
649 O_NONBLOCK on it. That way people can control if and when to block for
652 * hostnamed: populate form factor data from a new hwdb database, so that old
653 yogas can be recognized as "convertible" too, even if they predate the DMI
654 "convertible" form factor
656 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
657 after all. Be strict however, only support the equivalent of nspawn's
658 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
661 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
662 the service cgroup, which is supposed to monitor the service, and when it
663 exits the service is considered failed by its monitor.
665 * track the per-service PAM process properly (i.e. as an additional control
666 process), so that it may be queried on the bus and everything.
668 * add a new "debug" job mode, that is propagated to unit_start() and for
669 services results in two things: we raise SIGSTOP right before invoking
670 execve() and turn off watchdog support. Then, use that to implement
671 "systemd-gdb" for attaching to the start-up of any system service in its
674 * gpt-auto logic: related to the above, maybe support a "secondary" root
675 partition, that is mounted to / and is writable, and where the actual root's
676 /usr is mounted into.
678 * 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
680 * drop nss-myhostname in favour of nss-resolve?
682 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
683 then use that for the setting used in user@.service. It should be understood
684 relative to the configured default value.
686 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
688 * enable LockMLOCK to take a percentage value relative to physical memory
690 * Permit masking specific netlink APIs with RestrictAddressFamily=
692 * nspawn: support that /proc, /sys/, /dev are pre-mounted
694 * define gpt header bits to select volatility mode
696 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
698 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
700 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
702 * ProtectKeyRing= to take keyring calls away
704 * RemoveKeyRing= to remove all keyring entries of the specified user
706 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
707 on PID 1 with the relevant signals, and makes relevant files in /sys and
708 /proc (such as the sysrq stuff) unavailable
710 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
712 * journalctl: make sure -f ends when the container indicated by -M terminates
714 * mount: automatically search for "main" partition of an image has multiple
717 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
718 find a way to map the User=/Group= of the service to the right name. This way
719 a user/group for a service only has to exist on the host for the right
722 * add bus API for creating unit files in /etc, reusing the code for transient units
724 * add bus API to remove unit files from /etc
726 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
728 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
729 kernel doesn't support linkat() that replaces existing files, currently)
731 * transient units: don't bother with actually setting unit properties, we
732 reload the unit file anyway
734 * journald: sigbus API via a signal-handler safe function that people may call
735 from the SIGBUS handler
737 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
739 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
740 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
742 * cache sd_event_now() result from before the first iteration...
744 * PID1: find a way how we can reload unit file configuration for
745 specific units only, without reloading the whole of systemd
747 * add an explicit parser for LimitRTPRIO= that verifies
748 the specified range and generates sane error messages for incorrect
751 * when we detect that there are waiting jobs but no running jobs, do something
753 * push CPUAffinity= also into the "cpuset" cgroup controller
755 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
757 * there's probably something wrong with having user mounts below /sys,
758 as we have for debugfs. for example, src/core/mount.c handles mounts
759 prefixed with /sys generally special.
760 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
762 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
764 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
766 * add a job mode that will fail if a transaction would mean stopping
767 running units. Use this in timedated to manage the NTP service
769 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
771 * The udev blkid built-in should expose a property that reflects
772 whether media was sensed in USB CF/SD card readers. This should then
773 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
774 picked up by systemd unless they contain a medium. This would mirror
775 the behaviour we already have for CD drives.
777 * networkd/udev: implement SR_IOV configuration in .link files:
778 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
780 * hostnamectl: show root image uuid
782 * Find a solution for SMACK capabilities stuff:
783 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
785 * "systemctl preset-all" should probably order the unit files it
786 operates on lexicographically before starting to work, in order to
787 ensure deterministic behaviour if two unit files conflict (like DMs
790 * synchronize console access with BSD locks:
791 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
793 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
794 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
796 * figure out when we can use the coarse timers
798 * add "systemctl start -v foobar.service" that shows logs of a service
799 while the start command runs. This is non-trivial to do without
800 races though, since we should flush out all journal messages before
801 returning from the "systemctl stop".
803 * 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
805 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
807 * maybe allow timer units with an empty Units= setting, so that they
808 can be used for resuming the system but nothing else.
810 * what to do about udev db binary stability for apps? (raw access is not an option)
812 * systemctl: if some operation fails, show log output?
814 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
815 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
817 * exponential backoff in timesyncd when we cannot reach a server
819 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
821 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
823 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
824 (throughout the codebase, not only PID1)
828 - service registration
829 - service/domain/types browsing
831 - DNS-SD service registration from socket units
832 - resolved should optionally register additional per-interface LLMNR
833 names, so that for the container case we can establish the same name
834 (maybe "host") for referencing the server, everywhere.
835 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
836 - hook up resolved with machined-based address resolution
838 * refcounting in sd-resolve is borked
840 * Add a new verb "systemctl top"
842 * add new gpt type for btrfs volumes
844 * support empty /etc boots nicely:
845 - nspawn/gpt-generator: introduce new gpt partition type for /usr
847 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
849 * a way for container managers to turn off getty starting via $container_headless= or so...
851 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
853 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
854 they run added to the initial transaction and thus confuse Type=idle.
856 * add bus api to query unit file's X fields.
858 * gpt-auto-generator:
859 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
860 - Make /home automount rather than mount?
862 * add generator that pulls in systemd-network from containers when
863 CAP_NET_ADMIN is set, more than the loopback device is defined, even
864 when it is otherwise off
866 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
868 * implement Distribute= in socket units to allow running multiple
869 service instances processing the listening socket, and open this up
872 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
873 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
874 should SIGSTOP all unit processes in a loop until all processes of
875 it are fully stopped. This can later be used for app management by
876 desktop UIs such as gnome-shell to freeze apps that are not visible
877 on screen, not unlike how job control works on the shell
880 - implement per-slice CPUFairScheduling=1 switch
881 - introduce high-level settings for RT budget, swappiness
882 - how to reset dynamically changed unit cgroup attributes sanely?
883 - when reloading configuration, apply new cgroup configuration
884 - when recursively showing the cgroup hierarchy, optionally also show
885 the hierarchies of child processes
888 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
890 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
892 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
894 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
896 * 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
898 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
900 * If we try to find a unit via a dangling symlink, generate a clean
901 error. Currently, we just ignore it and read the unit from the search
904 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
906 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
908 * load .d/*.conf dropins for device units
912 - GetAllProperties() on a non-existing object does not result in a failure currently
913 - port to sd-resolve for connecting to TCP dbus servers
914 - 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
915 - see if we can drop more message validation on the sending side
916 - add API to clone sd_bus_message objects
917 - longer term: priority inheritance
919 - NameLost/NameAcquired obsolete
922 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
925 - allow multiple signal handlers per signal?
926 - document chaining of signal handler for SIGCHLD and child handlers
927 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
928 - maybe support iouring as backend, so that we allow hooking read and write
929 operations instead of IO ready events into event loops. See considerations
931 http://blog.vmsplice.net/2020/07/rethinking-event-loop-integration-for.html
933 * investigate endianness issues of UUID vs. GUID
935 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
936 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
938 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
940 * add a pam module that on password changes updates any LUKS slot where the password matches
943 - add unit tests for config_parse_device_allow()
945 * seems that when we follow symlinks to units we prefer the symlink
946 destination path over /etc and /usr. We should not do that. Instead
947 /etc should always override /run+/usr and also any symlink
950 * when isolating, try to figure out a way how we implicitly can order
951 all units we stop before the isolating unit...
953 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
955 * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
956 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
957 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
959 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
960 that the boot loader should be installed to the ESP. Define a way
961 how an installer can figure out whether a BLS compliant boot loader
964 * think about requeuing jobs when daemon-reload is issued? usecase:
965 the initrd issues a reload after fstab from the host is accessible
966 and we might want to requeue the mounts local-fs acquired through
969 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
971 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
973 * shutdown logging: store to EFI var, and store to USB stick?
975 * merge unit_kill_common() and unit_kill_context()
978 - honor language efi variables for default language selection (if there are any?)
979 - honor timezone efi variables for default timezone selection (if there are any?)
980 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
982 - recognize the case when not booted on EFI
984 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
986 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
988 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
991 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
992 - logind: wakelock/opportunistic suspend support
993 - Add pretty name for seats in logind
994 - logind: allow showing logout dialog from system?
995 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
996 - if pam_systemd is invoked by su from a process that is outside of a
997 any session we should probably just become a NOP, since that's
998 usually not a real user session but just some system code that just
1000 - logind: make the Suspend()/Hibernate() bus calls wait for the for
1001 the job to be completed. before returning, so that clients can wait
1002 for "systemctl suspend" to finish to know when the suspending is
1004 - logind: when the power button is pressed short, just popup a
1005 logout dialog. If it is pressed for 1s, do the usual
1006 shutdown. Inspiration are Macs here.
1007 - expose "Locked" property on logind sesison objects
1008 - maybe allow configuration of the StopTimeout for session scopes
1009 - rename session scope so that it includes the UID. THat way
1010 the session scope can be arranged freely in slices and we don't have
1011 make assumptions about their slice anymore.
1012 - follow PropertiesChanged state more closely, to deal with quick logouts and
1014 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
1017 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
1018 - journald: also get thread ID from client, plus thread name
1019 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
1020 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
1021 - fall back to /dev/log based logging in libsystemd-journal, if we cannot log natively?
1022 - declare the local journal protocol stable in the wiki interface chart
1023 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
1024 - journald: when dropping msgs due to ratelimit make sure to write
1025 "dropped %u messages" not only when we are about to print the next
1026 message that works, but already after a short timeout
1027 - check if we can make journalctl by default use --follow mode inside of less if called without args?
1028 - maybe add API to send pairs of iovecs via sd_journal_send
1029 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
1030 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
1031 and !FOOBAR for events without FOOBAR.
1032 - journal: store timestamp of journal_file_set_offline() in the header,
1033 so it is possible to display when the file was last synced.
1034 - 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.
1035 - journal: find a way to allow dropping history early, based on priority, other rules
1036 - journal: When used on NFS, check payload hashes
1037 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
1038 - refuse taking lower-case variable names in sd_journal_send() and friends.
1039 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
1040 - journal: deal nicely with byte-by-byte copied files, especially regards header
1041 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
1042 - Replace utmp, wtmp, btmp, and lastlog completely with journal
1043 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
1044 - when a kernel driver logs in a tight loop, we should ratelimit that too.
1045 - journald: optionally, log debug messages to /run but everything else to /var
1046 - journald: when we drop syslog messages because the syslog socket is
1047 full, make sure to write how many messages are lost as first thing
1048 to syslog when it works again.
1049 - journald: allow per-priority and per-service retention times when rotating/vacuuming
1050 - journald: make use of uid-range.h to managed uid ranges to split
1052 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
1053 - improve journalctl performance by loading journal files
1054 lazily. Encode just enough information in the file name, so that we
1055 do not have to open it to know that it is not interesting for us, for
1056 the most common operations.
1057 - man: document that corrupted journal files is nothing to act on
1058 - rework journald sigbus stuff to use mutex
1059 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
1060 services that run under their own user ids, and use User= (but only
1061 in a world where userns is ubiquitous since otherwise we cannot
1062 invoke those daemons on the host AND in a container anymore). Also,
1063 if LimitNPROC= is used without User= we should warn and refuse
1065 - journalctl --verify: don't show files that are currently being
1066 written to as FAIL, but instead show that their are being written to.
1067 - add journalctl -H that talks via ssh to a remote peer and passes through
1069 - add a version of --merge which also merges /var/log/journal/remote
1070 - journalctl: -m should access container journals directly by enumerating
1071 them via machined, and also watch containers coming and going.
1072 Benefit: nspawn --ephemeral would start working nicely with the journal.
1073 - assign MESSAGE_ID to log messages about failed services
1074 - check if loop in decompress_blob_xz() is necessary
1076 * add a test if all entries in the catalog are properly formatted.
1077 (Adding dashes in a catalog entry currently results in the catalog entry
1078 being silently skipped. journalctl --update-catalog must warn about this,
1079 and we should also have a unit test to check that all our message are OK.)
1082 - document that deps in [Unit] sections ignore Alias= fields in
1083 [Install] units of other units, unless those units are disabled
1084 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
1085 - document that service reload may be implemented as service reexec
1086 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1087 - document systemd-journal-flush.service properly
1088 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1089 - man: document the very specific env the shutdown drop-in tools live in
1090 - man: add more examples to man pages,
1091 - in particular an example how to do the equivalent of switching runlevels
1092 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
1093 - document root=gpt-auto properly
1096 - add systemctl switch to dump transaction without executing it
1097 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1098 - "systemctl disable" on a static unit prints no message and does
1099 nothing. "systemctl enable" does nothing, and gives a bad message
1100 about it. Should fix both to print nice actionable messages.
1101 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1102 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
1103 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
1104 - systemctl: "Journal has been rotated since unit was started." message is misleading
1105 - systemctl status output should include list of triggering units and their status
1108 - "systemctl mask" should find all names by which a unit is accessible
1109 (i.e. by scanning for symlinks to it) and link them all to /dev/null
1112 - timer units should get the ability to trigger when:
1114 - Modulate timer frequency based on battery state
1116 * add libsystemd-password or so to query passwords during boot using the password agent logic
1118 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1120 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
1122 * make repeated alt-ctrl-del presses printing a dump
1124 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1126 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1129 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1130 with seccomp. That should provide us with a useful log buffer that
1131 systemd can log to during early boot, and disconnect container logs
1132 from the kernel's logs.
1133 - as soon as networkd has a bus interface, hook up --network-interface=,
1134 --network-bridge= with networkd, to trigger netdev creation should an
1135 interface be missing
1136 - a nice way to boot up without machine id set, so that it is set at boot
1137 automatically for supporting --ephemeral. Maybe hash the host machine id
1138 together with the machine name to generate the machine id for the container
1139 - fix logic always print a final newline on output.
1140 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1141 - should optionally support receiving WATCHDOG=1 messages from its payload
1143 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1144 running, remove them when shut down.
1147 - add an API so that libvirt-lxc can inform us about network interfaces being
1148 removed or added to an existing machine
1149 - "machinectl migrate" or similar to copy a container from or to a
1150 difference host, via ssh
1151 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1152 "machinectl start" with a new --ephemeral switch
1153 - "machinectl status" should also show internal logs of the container in
1155 - "machinectl history"
1157 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1158 shell in it, and marks it read-only after use
1161 - cryptsetup-generator: allow specification of passwords in crypttab itself
1162 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
1164 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
1165 https://bugs.freedesktop.org/show_bug.cgi?id=54712
1167 * add a dependency on standard-conf.xml and other included files to man pages
1169 * MountFlags=shared acts as MountFlags=slave right now.
1171 * properly handle loop back mounts via fstab, especially regards to fsck/passno
1173 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1178 - add trigger --subsystem-match=usb/usb_device device
1179 - reimport udev db after MOVE events for devices without dev_t
1181 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1183 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1186 - save coredump in Windows/Mozilla minidump format
1187 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
1189 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1191 * be able to specify a forced restart of service A where service B depends on, in case B
1192 needs to be auto-respawned?
1195 - apply "x" on "D" too (see patch from William Douglas)
1196 - instead of ignoring unknown fields, reject them.
1197 - creating new directories/subvolumes/fifos/device nodes
1198 should not follow symlinks. None of the other adjustment or creation
1199 calls follow symlinks.
1201 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1203 * verify that the AF_UNIX sockets of a service in the fs still exist
1204 when we start a service in order to avoid confusion when a user
1205 assumes starting a service is enough to make it accessible
1207 * Make it possible to set the keymap independently from the font on
1208 the kernel cmdline. Right now setting one resets also the other.
1210 * and a dbus call to generate target from current state
1212 * write blog stories about:
1213 - hwdb: what belongs into it, lsusb
1214 - enabling dbus services
1215 - how to make changes to sysctl and sysfs attributes
1217 - how to pass throw-away units to systemd, or dynamically change properties of existing units
1218 - testing with Harald's awesome test kit
1220 - how to develop against journal browsing APIs
1221 - the journal HTTP iface
1222 - non-cgroup resource management
1223 - dynamic resource management with cgroups
1224 - refreshed, longer missions statement
1225 - calendar time events
1226 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
1227 - how to create your own target
1228 - instantiated apache, dovecot and so on
1229 - hooking a script into various stages of shutdown/rearly booot
1231 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1233 * dot output for --test showing the 'initial transaction'
1236 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1237 log both units as UNIT=, so that journalctl -u triggers on both.
1238 - generate better errors when people try to set transient properties
1239 that are not supported...
1240 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1241 - maybe introduce WantsMountsFor=? Usecase:
1242 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1243 - recreate systemd's D-Bus private socket file on SIGUSR2
1244 - move PAM code into its own binary
1245 - when we automatically restart a service, ensure we restart its rdeps, too.
1246 - hide PAM options in fragment parser when compile time disabled
1247 - Support --test based on current system state
1248 - 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().
1249 - after deserializing sockets in socket.c we should reapply sockopts and things
1250 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1251 currently is properly synchronous, Reexec() is weird, because we
1252 cannot delay the response properly until we are back, so instead of
1253 being properly synchronous we just keep open the fd and close it
1254 when done. That means clients do not get a successful method reply,
1255 but much rather a disconnect on success.
1256 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1257 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1260 - allow port=0 in .socket units
1261 - maybe introduce ExecRestartPre=
1262 - add ReloadSignal= for configuring a reload signal to use
1263 - implement Register= switch in .socket units to enable registration
1264 in Avahi, RPC and other socket registration services.
1265 - allow Type=simple with PIDFile=
1266 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1267 - allow writing multiple conditions in unit files on one line
1268 - introduce Type=pid-file
1269 - introduce mix of BindTo and Requisite
1270 - add a concept of RemainAfterExit= to scope units
1271 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1272 - add verification of [Install] section to systemd-analyze verify
1275 - Make sure ID_PATH is always exported and complete for
1276 network devices where possible, so we can safely rely
1280 - add support for more attribute types
1281 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1284 - add more keys to [Route] and [Address] sections
1285 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1286 - add reduced [Link] support to .network files
1287 - properly handle routerless dhcp leases
1288 - work with non-Ethernet devices
1289 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1290 - the DHCP lease data (such as NTP/DNS) is still made available when
1291 a carrier is lost on a link. It should be removed instantly.
1292 - expose in the API the following bits:
1293 - option 15, domain name
1294 - option 12, hostname and/or option 81, fqdn
1295 - option 123, 144, geolocation
1296 - option 252, configure http proxy (PAC/wpad)
1297 - provide a way to define a per-network interface default metric value
1298 for all routes to it. possibly a second default for DHCP routes.
1299 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1300 support Name=foo*|bar*|baz ?
1301 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1302 - whenever uplink info changes, make DHCP server send out FORCERENEW
1304 * Figure out how to do unittests of networkd's state serialization
1307 - figure out how much we can increase Maximum Message Size
1310 - add functions to set previously stored IPv6 addresses on startup and get
1311 them at shutdown; store them in client->ia_na
1312 - write more test cases
1313 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1314 - implement support for temporary adressess (IA_TA)
1315 - implement dhcpv6 authentication
1316 - investigate the usefulness of Confirm messages; i.e. are there any
1317 situations where the link changes without any loss in carrier detection
1319 - some servers don't do rapid commit without a filled in IA_NA, verify
1326 - natively watch for dbus-*.service symlinks (PENDING)
1327 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1329 * make cryptsetup lower --iter-time
1331 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1333 * /usr/bin/service should actually show the new command line
1335 * 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=
1337 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1339 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1341 * register catalog database signature as file magic
1343 * zsh shell completion:
1344 - <command> <verb> -<TAB> should complete options, but currently does not
1345 - systemctl add-wants,add-requires
1347 * systemctl status should know about 'systemd-analyze calendar ... --iterations='
1348 * If timer has just OnInactiveSec=..., it should fire after a specified time
1349 after being started.
1353 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1355 * check for strerror(r) instead of strerror(-r)
1359 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1361 * use secure_getenv() instead of getenv() where appropriate
1363 * link up selected blog stories from man pages and unit files Documentation= fields
1364 String is not UTF-8 clean, ignoring assignment
