Bugfixes:
-* killing nspawn with ]]] results in:
- machine-f20.scope stopping timed out. Killing.
- Stopped Container f20.
- Unit machine-f20.scope entered failed state.
- and it cannot be started again
+* Should systemctl status \* work on all unit types, not just .service?
* enabling an instance unit creates a pointless link, and
the unit will be started with getty@getty.service:
* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
-* When we detect invalid UTF-8, we cannot use it in an error message:
- log...("Path is not UTF-8 clean, ignoring assignment: %s", rvalue);
-
* shorten the message to sane length:
Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.
-* systemctl --root=container/ set-default ... is totally borked.
+* sd_bus_unref() is broken regarding self-references and "pseudo thread-safety".
+ See the comment in sd_bus_unref() for more..
External:
-* ps should gain colums for slice
-
* Fedora: when installing fedora with yum --installroot /var/run is a directory, not a symlink
https://bugzilla.redhat.com/show_bug.cgi?id=975864
Features:
-* hookup nspawn and PrivateNetwork=yes with "ip netns"
+* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
+
+* support setting empty environment variables with Environment= and EnvironmentFile=
+
+* tmpfiles: figure out relation between Z and m?
+
+* systemd-notify: fake ucred of msg to PID of parent, if that works, with fallback to our own if it doesn't.
+
+* machined/machinectl: sort IP addresses we return by scope and protocol
+* machined: write NSS module for looking up IP addresses for machines
+
+* timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
+
+* timesyncd:
+ - hookup with networkd: NTP servers from dhcp
+
+* a way for container managers to turn off getty starting via $container_headless= or so...
+
+* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
+
+* add a kernel command line option to enable the debug shell
+
+* journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
+
+* set NOTIFY_SOCKET also for control processes
+
+* drop parsing of chkconfig header lines from service.c
+
+* mount_cgroup_controllers(): symlinks need to get the label applied
+
+* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services they run added to the initial transaction and thus confuse Type=idle.
+
+* Add RPM macros for registering/unregistering binfmt drop-ins
+
+* Add timeout to early-boot, and shut down the system if it is hit. Solves the laptop-in-bag problem and is useful for embedded cases
+
+* ImmutableSystem=yes/no or so to mount /usr, /boot read-only/invisible, and leave /var and /etc writable
+
+* InaccessibleHome=yes/no or so to hide /home and /run/user from a service
+
+* Run most system services with cgroupfs read-only and procfs with a more secure mode
+
+* sd-event: generate a failure of a default event loop is executed out-of-thread
+
+* add "M" as recursive version of "m" to tmpfiles, then use it for
+ chowning /run/log/journal (but not /var/log/journal), so that we
+ adjust the perms of journal files created before tmpfiles ran.
+
+* expose "Locked" property on logind sesison objects
+
+* add bus api to query unit file's X fields.
+
+* consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
+
+* sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
+
+* gpt-auto-generator:
+ - Support LUKS for root devices
+ - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
+ - Make /home automount rather than mount?
+
+* improve journalctl performance by loading journal files
+ lazily. Encode just enough information in the file name, so that we
+ do not have to open it to know that it is not interesting for us, for
+ the most common operations.
+
+* support transient mount units
+
+* add an "input" group to udev logic and add all input devices to it
+
+* add generator that pulls in systemd-network from containers when
+ CAP_NET_ADMIN is set, more than the loopback device is defined, even
+ when it is otherwise off
+
+* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
+
+* "busctl status" works only as root on dbus1, since we cannot read
+ /proc/$PID/exe
+
+* implement Distribute= in socket units to allow running multiple
+ service instances processing the listening socket, and open this up
+ for ReusePort=
* socket units: support creating sockets in different namespace,
opening it up for JoinsNamespaceOf=. This would require to fork off
and passes this back to PID1 via SCM_RIGHTS. This also could be used
to allow Chown/chgrp on sockets without requiring NSS in PID 1.
-* sd-resolve:
- - make sure event loop integration works similar to event loop integration in other libs
- - maybe drop _free() call, introduce _unref() instead
- - maybe simplify function calls that take a sd_resolve_query object, to not also require the matching sd_resolve?
- - maybe drop the "n_proc" parameter to sd_resolve_new()?
- - change all functions to return "int" and negative errno errors
-
* New service property: maximum CPU and wallclock runtime for a service
* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
desktop UIs such as gnome-shell to freeze apps that are not visible
on screen, not unlike how job control works on the shell
-* machinectl bash completion is missing
-* busctl bash and zsh completions are outdated
-
-* Introduce PrivateDevices=yes/no which works like PrivateTmp= but for /dev setting up a tmpfs for it that only includes /dev/null, /dev/zero, /dev/random, /dev/urandom, but nothing else.
-
-* libsystemd-journal returns the object created as first param in sd_journal_new(), sd_bus_new() and suchlike as last...
+* completions:
+ - manager property enumeration was broken when systemd moved to /usr/lib/
* cgroups:
- - implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
- implement per-slice CPUFairScheduling=1 switch
- handle jointly mounted controllers correctly
- introduce high-level settings for RT budget, swappiness
- add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
- ensure scope units may be started only a single time
-* code cleanup
- - we probably should replace the left-over uses of strv_append() and replace them by strv_push() or strv_extend()
-
* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
* when we detect low battery and no AC on boot, show pretty splash and refuse boot
-* move libasyncns into systemd as libsystemd-asyncns
-
* machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
-* socket-proxyd:Use a nonblocking alternative to getaddrinfo
+* socket-proxyd: Use sd-resolve to resolve the server address
* 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
-* Add a new Distribute=$NUMBER key to socket units that makes use of SO_REUSEPORT to distribute network traffic on $NUMBER instances
-
-* move config_parse_path_strv() out of conf-parser.c
-
* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
* If we try to find a unit via a dangling symlink, generate a clean
error. Currently, we just ignore it and read the unit from the search
path anyway.
-* When a Type=forking service fails and needed another service, that
- service is not cleaned up again when it has StopWhenUnneeded=yes
- http://lists.freedesktop.org/archives/systemd-devel/2013-July/012141.html
-
* refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
* given that logind now lets PID 1 do all nasty work, we can
* btrfs raid assembly: some .device jobs stay stuck in the queue
-* make sure gdm doesn't use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
+* make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
* load .d/*.conf dropins for device units
-* gparted needs to disable auto-activation of mount units somehow, or
- maybe we should stop doing auto-activation of this after boot
- entirely. https://bugzilla.gnome.org/show_bug.cgi?id=701676
- Maybe take a BSD lock at the disk device node and teach udev to
- check for that and suppress event handling.
-
-* something pulls in pcre as shared object dependency into our daemons such as hostnamed.
-
* allow implementation of InaccessibleDirectories=/ plus
ReadOnlyDirectories=... for whitelisting files for a service.
* sd-bus:
- - when kdbus doesn't take our message without memfds, try again with memfds
- - implement monitor logic
+ - make AddMatch calls on dbus1 transports async
+ - when kdbus does not take our message without memfds, try again with memfds
+ - systemd-bus-proxyd needs to enforce good old XML policy
+ - port exit-on-idle logic to byebye ioctl
+ - allow updating attach flags during runtime
+ - pid1: peek into activating message when activating a service
+ - introduce sd_bus_emit_object_added()/sd_bus_emit_object_removed() that automatically includes the build-in interfaces in the list
+ - constructors for bus messages should probably not be OK with a NULL bus pointer
+ - .busname units should not use get_user_creds()/get_cgroup_creds() but instead do NSS only in temporarily forked off child
- see if we can drop more message validation on the sending side
- add API to clone sd_bus_message objects
- - systemd-bus-proxyd needs to enforce good old XML policy
- - upload minimal kdbus policy into the kernel at boot
- kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
- longer term: priority inheritance
- - check sender of response messages
- dbus spec updates:
- kdbus mapping
- NameLost/NameAcquired obsolete
- GVariant
- "const" properties (posted)
- - port exit-on-idle logic to byebye ioctl
- - bus proxy: override unique id sender for messages from driver to match the well-known name
- - bus driver: GetNameOwner() for "org.freedesktop.DBus" should return "org.freedesktop.DBus"
+ - path escaping
- update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
- - bus proxy should fake seclabel when connecting to kdbus
- - allow updating attach flags during runtime
- - pid1: peek into activating message when activating a service
- - when service activation failed, drop one message from the activator queue
+ - test bloom filter generation indexes
+ - port to sd-resolve for connecting to TCP dbus servers
* sd-event
- allow multiple signal handlers per signal?
complain loudly if they have argv[0][0] == '@' set.

-* Introduce a way how we can kill the main process of a service with KillSignal, but all processes with SIGKILL later on
- https://bugzilla.redhat.com/show_bug.cgi?id=952634
-
-* maybe add a warning to the unit file parses where the access mode of unit files is nonsensical.
-
* investigate endianness issues of UUID vs. GUID
* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
file.
* seems that when we follow symlinks to units we prefer the symlink
- destination path over /etc and /usr. We shouldn't do that. Instead
+ destination path over /etc and /usr. We should not do that. Instead
/etc should always override /run+/usr and also any symlink
destination.
* when isolating, try to figure out a way how we implicitly can order
all units we stop before the isolating unit...
-* add ConditionArchitecture= or so
-
* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
-* Support SO_REUSEPORT with socket activation:
- - Let systemd maintain a pool of servers.
- - Use for seamless upgrades, by running the new server before stopping the
- old.
-
* after all byte-wise realloc() is slow, even on glibc, so i guess we
need manual exponential loops after all
-* BootLoaderSpec: drop allowing ext234 for $BOOT. Clarify that the
- kernel has to be in $BOOT. Clarify that the boot loader should be
- installed to the ESP. Define a way how an installer can figure out
- whether a BLS compliant boot loader is installed.

* think about requeuing jobs when daemon-reload is issued? usecase:
the initrd issues a reload after fstab from the host is accessible

-* remove any syslog support from log.c -- we probably can't do this before split-off udev is gone for good
+* remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
* shutdown logging: store to EFI var, and store to USB stick?
* timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
-* dev-setup.c: when running in a container, create a tiny stub udev
- database with the systemd tag set for all network interfaces found,
- so that libudev reports them as present, and systemd's .device units
- will be activated.
-
* merge unit_kill_common() and unit_kill_context()
* introduce ExecCondition= in services
* EFI:
- - write man page for efi boot generator
- honor language efi variables for default language selection (if there are any?)

- Add pretty name for seats in logind
- logind: allow showing logout dialog from system?
- - logind: non-local X11 server handling
- - logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
- - pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree
- we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
- - when logging out, remove user-owned sysv and posix IPC objects
- session scopes/user unit: add RequiresMountsFor for the home directory of the user
- add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
- if pam_systemd is invoked by su from a process that is outside of a
- journald: also get thread ID from client, plus thread name
- journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
- add API to close/reopen/get fd for journal client fd in libsystemd-journal.
- - fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
+ - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
- declare the local journal protocol stable in the wiki interface chart
- journal: reuse XZ context
- sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
- journald: make sure ratelimit is actually really per-service with the new cgroup changes
- change systemd-journal-flush into a service that stays around during
boot, and causes the journal to be moved back to /run on shutdown,
- so that we don't keep /var busy. This needs to happen synchronously,
+ so that we do not keep /var busy. This needs to happen synchronously,
hence doing this via signals is not going to work.
* document:
- document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
- add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
- document systemd-journal-flush.service properly
- - man: remove .include documentation, and instead push people to use .d/*.conf
- documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
- man: document the very specific env the shutdown drop-in tools live in
- man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
- print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
- add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
- systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
- - systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
+ - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
- systemctl: "Journal has been rotated since unit was started." message is misleading
- support "systemctl stop foobar@.service" to stop all units matching a certain template
- Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
- - rework wait filter to not require match callback
- better error message if you run systemctl without systemd running
- systemctl status output should should include list of triggering units and their status
- - in systemctl list-timers show time triggering units ran last
* unit install:
- "systemctl mask" should find all names by which a unit is accessible
- systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
- systemctl: maybe add "systemctl add-wants" or so...
-* introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
-
* deal with sendmail/postfix exclusivity
* timer units:

o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
o DST changes
- Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
- calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
- - when parsing calendar timestamps support the UTC timezone (even if we won't support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
+ - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
- Modulate timer frequency based on battery state
- - anacron-like feature
* update the kernel's TZ (sys_tz) when DST changes
mode, it will never touch the RTC if the no reliable time source is active or the
user did not request anything like it.
-* if booted in "quiet" mode, and an error happens, turn on status
- output again, so that the emergency mode isn't totally
- surprising. Also, terminate plymouth.
-
* libunwind support for coredump pattern hook, and includes this in
the message for coredumps. After all, libunwind is now capable to
unwind coredumps since a few weeks ago. This probably requires that
* 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().
* fedup: add --unit to systemctl switch-root somehow
-* fedup: don't delete initrd on switch-root
+* fedup: do not delete initrd on switch-root

+ - nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters
- refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
- - add an option to nspawn that uses seccomp to make socket(AF_NETLINK,

- makes the audit userspace to think auditing is not available in the
- kernel.
- support taking a btrfs snapshot at startup and dropping it afterwards
