2014-11-05core: introduce new Delegate=yes/no property controlling creation of cgroup ↵Lennart Poettering
subhierarchies For priviliged units this resource control property ensures that the processes have all controllers systemd manages enabled. For unpriviliged services (those with User= set) this ensures that access rights to the service cgroup is granted to the user in question, to create further subgroups. Note that this only applies to the name=systemd hierarchy though, as access to other controllers is not safe for unpriviliged processes. Delegate=yes should be set for container scopes where a systemd instance inside the container shall manage the hierarchies below its own cgroup and have access to all controllers. Delegate=yes should also be set for user@.service, so that systemd --user can run, controlling its own cgroup tree. This commit changes machined, systemd-nspawn@.service and user@.service to set this boolean, in order to ensure that container management will just work, and the user systemd instance can run fine.
2014-11-04units: make systemd-journald.service Type=notifyMichal Schmidt
It already calls sd_notify(), so it looks like an oversight. Without it, its ordering to systemd-journal-flush.service is non-deterministic and the SIGUSR1 from flushing may kill journald before it has its signal handlers set up. https://bugs.freedesktop.org/show_bug.cgi?id=85871 https://bugzilla.redhat.com/show_bug.cgi?id=1159641

2014-11-02units: order sd-journal-flush after sd-remount-fsZbigniew Jędrzejewski-Szmek
Otherwise we could attempt to flush the journal while /var/log/ was still ro, and silently skip journal flushing. The way that errors in flushing are handled should still be changed to be more transparent and robust.
2014-11-02unit: do not order timers.target before basic.targetZbigniew Jędrzejewski-Szmek
Since commit 19f8d037833f2 'timer: order OnCalendar units after timer-sync.target if DefaultDependencies=no' timers might get a dependency on time-sync.target, which does not really belong in early boot. If ntp is enabled, time-sync.target might be delayed until a network connection is established. It turns out that majority of timer units found in the wild do not need to be started in early boot. Out of the timer units available in Fedora 21, only systemd-readahead-done.timer and mdadm-last-resort@.timer should be started early, but they both have DefaultDependencies=no, so are not part of timers.target anyway. All the rest look like they will be fine with being started a bit later (and the majority even much later, since they run daily or weekly). Let timers.target be pulled in by basic.target, but without the temporal dependency. This means timer units are started on a "best effort" schedule. https://bugzilla.redhat.com/show_bug.cgi?id=1158206
2014-11-01systemd-journal-flush.service: remove "trigger" from descriptionZbigniew Jędrzejewski-Szmek
This service is now synchronous, so "trigger" is misleading.
2014-10-31units: don't order journal flushing afte remote-fs.targetLennart Poettering
Instead, only depend on the actual file systems we need. This should solve dep loops on setups where remote-fs.target is moved into late boot.
2014-10-28udev hwdb: Support shipping pre-compiled database in system imagesMartin Pitt
In some cases it is preferable to ship system images with a pre-generated binary hwdb database, to avoid having to build it at runtime, avoid shipping the source hwdb files, or avoid storing large binary files in /etc. So if hwdb.bin does not exist in /etc/udev/, fall back to looking for it in UDEVLIBEXECDIR. This keeps the possibility to add files to /etc/udev/hwdb.d/ and re-generating the database which trumps the one in /usr/lib. Add a new --usr flag to "udevadm hwdb --update" which puts the database into UDEVLIBEXECDIR. Adjust systemd-udev-hwdb-update.service to not generate the file in /etc if we already have it in /usr.
2014-10-28units: define appropriate job timeout actions when boot or shutdown timeouts ↵Lennart Poettering
are hit Using the new JobTimeoutAction= setting make sure we power off the machine after basic.target is queued for longer than 15min but not executed. Similar, if poweroff.target is queued for longer than 30min but does not complete, forcibly turn off the system. Similar, if reboot.target is queued for longer than 30min but does not complete, forcibly reboot the system.
2014-10-27units: tmpfiles-setup-dev - allow unsafe file creation to happen in /dev at bootTom Gundersen
This will allow us to mark static device nodes with '!' to indicate that they should only be created at early boot.

root password
2014-10-23journalctl: add new --flush command and make use of it in ↵Lennart Poettering
systemd-journal-flush.service This new command will ask the journal daemon to flush all log data stored in /run to /var, and wait for it to complete. This is useful, so that in case of Storage=persistent we can order systemd-tmpfiles-setup afterwards, to ensure any possibly newly created directory in /var/log gets proper access mode and owners.
2014-10-22journald: add CAP_MAC_OVERRIDE in journald for SMACK issueJuho Son
systemd-journald check the cgroup id to support rate limit option for every messages. so journald should be available to access cgroup node in each process send messages to journald. In system using SMACK, cgroup node in proc is assigned execute label as each process's execute label. so if journald don't want to denied for every process, journald should have all of access rule for all process's label. It's too heavy. so we could give special smack label for journald te get all accesses's permission. '^' label. When assign '^' execute smack label to systemd-journald, systemd-journald need to add CAP_MAC_OVERRIDE capability to get that smack privilege. so I want to notice this information and set default capability to journald whether system use SMACK or not. because that capability affect to only smack enabled kernel
2014-10-09systemd-hibernate-resume@.service: remove unnecessary orderingIvan Shapovalov
They were left from an early review iteration, when hibernate-resume functionality was intended to work also outside of initramfs. Now this is not the case, and these dependencies became redundant as systemd-fsck-root.service can never be part of initramfs, and systemd-remount-fs.service makes little sense in it.

2014-09-08units: networkd - order after udevTom Gundersen
This way we are sure that /dev/net/tun has been given the right permissions before we try to connect to it. Ideally, we should create tun/tap devices over netlink, and then this whole issue would go away.
2014-09-03initrd-parse-etc.service: ignore return code of daemon-reloadHarald Hoyer
It seems the return code of systemctl daemon-reload can be !=0 in some circumstances, which causes a failure of the unit and breaks booting in the initrd.

2014-08-26hibernate-resume: add a tool to write a device node's major:minor to ↵Ivan Shapovalov
/sys/power/resume. This can be used to initiate a resume from hibernation by path to a swap device containing the hibernation image. The respective templated unit is also added. It is instantiated using path to the desired resume device.
2014-08-26units: order systemd-fsck@.service after local-fs-pre.target.Ivan Shapovalov
With this change, it becomes possible to order a unit to activate before any modifications to the file systems. This is especially useful for supporting resume from hibernation.

2014-07-15units/serial-getty@.service: use the default RestartSecMichael Olbrich
For pluggable ttys such as USB serial devices, the getty is restarted and exits in a loop until the remove event reaches systemd. Under certain circumstances the restart loop can overload the system in a way that prevents the remove event from reaching systemd for a long time (e.g. at least several minutes on a small embedded system). Use the default RestartSec to prevent the restart loop from overloading the system. Serial gettys are interactive units, so waiting an extra 100ms really doesn't make a difference anyways compared to the time it takes the user to log in.

2014-07-09units: make ExecStopPost action part of ExecStartMichal Sekletar
Currently after exiting rescue shell we isolate default target. User might want to isolate to some other target than default one. However issuing systemctl isolate command to desired target would bring system to default target as a consequence of running ExecStopPost action. Having common ancestor for rescue shell and possible followup systemctl default command should fix this. If user exits rescue shell we will proceed with isolating default target, otherwise, on manual isolate, parent shell process is terminated and we don't isolate default target, but target chosen by user.

2014-07-07firstboot: get rid of firstboot generator again, introduce ↵Lennart Poettering
ConditionFirstBoot= instead As Zbigniew pointed out a new ConditionFirstBoot= appears like the nicer way to hook in systemd-firstboot.service on first boots (those with /etc unpopulated), so let's do this, and get rid of the generator again.
2014-07-07firstboot: add new component to query basic system settings on first boot, ↵Lennart Poettering
or when creating OS images offline A new tool "systemd-firstboot" can be used either interactively on boot, where it will query basic locale, timezone, hostname, root password information and set it. Or it can be used non-interactively from the command line when prepareing disk images for booting. When used non-inertactively the tool can either copy settings from the host, or take settings on the command line. $ systemd-firstboot --root=/path/to/my/new/root --copy-locale --copy-root-password --hostname=waldi The tool will be automatically invoked (interactively) now on first boot if /etc is found unpopulated. This also creates the infrastructure for generators to be notified via an environment variable whether they are running on the first boot, or not.
2014-07-04units: conditionalize configfs and debugfs with CAP_SYS_RAWIOLennart Poettering
We really don't want these in containers as they provide a too lowlevel look on the system. Conditionalize them with CAP_SYS_RAWIO since that's required to access /proc/kcore, /dev/kmem and similar, which feel similar in style. Also, npsawn containers lack that capability.
2014-07-04units: conditionalize static device node logic on CAP_SYS_MODULES instead of ↵Lennart Poettering
CAP_MKNOD npsawn containers generally have CAP_MKNOD, since this is required to make PrviateDevices= work. Thus, it's not useful anymore to conditionalize the kmod static device node units. Use CAP_SYS_MODULES instead which is not available for nspawn containers. However, the static device node logic is only done for being able to autoload modules with it, and if we can't do that there's no point in doing it.

Reported by Michael Olbrich.
2014-06-29units: local-fs.target - don't pull in default dependenciesTom Gundersen
Reported by Gerardo Exequiel Pozzi: Looks like [commit a4a878d0] also changes a unrelated file (units/local-fs.target) [partially]reverting the commit 40f862e3 (filesystem targets: disable default dependencies) The side effect, at least in my case is that the "nofail" option in both "crypttab" and "fstab" has partial effect does the default timeout instead of continue normal boot without timeout.
2014-06-28units: remove RefuseManualStart from units which are always aroundZbigniew Jędrzejewski-Szmek
In a normal running system, non-passive targets and units used during early bootup are always started. So refusing "manual start" for them doesn't make any difference, because a "start" command doesn't cause any action. In early boot however, the administrator might want to start on of those targets or services by hand. We shouldn't interfere with that. Note: in case of systemd-tmpfiles-setup.service, really running the unit after system is up would break the system. So e.g. restarting should not be allowed. The unit has "RefuseManualStop=yes", which prevents restart too.
2014-06-19units/systemd-sysctl.service.in: run after load-modulesCristian Rodríguez
Modules might or will register new sysctl options. [zj: This mechanism of adding modules just to reliably set sysctl attributes is not ideal. Nevertheless, sysctl for dynamically created attributes is simply broken, and this is the easiest workaround.] https://bugzilla.redhat.com/show_bug.cgi?id=1022977 https://bugzilla.novell.com/show_bug.cgi?id=725412
