Adds a new call sd_event_set_watchdog() that can be used to hook up the
event loop with the watchdog supervision logic of systemd. If enabled
and $WATCHDOG_USEC is set the event loop will ping the invoking systemd
daemon right after coming back from epoll_wait() but not more often than
$WATCHDOG_USEC/4. The epoll_wait() will sleep no longer than
$WATCHDOG_USEC/4*3, to make sure the service manager is called in time.
This means that setting WatchdogSec= in a .service file and calling
sd_event_set_watchdog() in your daemon is enough to hook it up with the
watchdog logic.

This daemon listens for and configures network devices tagged with
'systemd-networkd'. By default, no devices are tagged so this daemon
can safely run in parallel with existing network daemons/scripts.
Networks are configured in /etc/systemd/network/*.network. The first .network
file that matches a given link is applied. The matching logic is similar to
the one for .link files, but additionally supports matching on interface name.
The mid-term aim is to provide an alternative to ad-hoc scripts currently used
in initrd's and for wired setups that don't change much (e.g., as seen on
servers/and some embedded systems).
Currently, static addresses and a gateway can be configured.
Example .network file:
[Match]
Name=wlp2s0
[Network]
Description=My Network
Gateway=192.168.1.1
Address=192.168.1.23/24
Address=fe80::9aee:94ff:fe3f:c618/64

instead of using FsckPassNo
[tomegun:
* order all fsck instances after fsck-root
* check for OOM
* added notes in the manpages]

This is no longer necessary with kmod-15. Bump the requirement.
|
|
This works analogous to the existing backlight and random seed services
|

In e6dca81 $SHELL was added to user@.service. Let's
instead provide it to all units which have a user.

DRM Master access requires CAP_SYS_ADMIN, yay! Add it to the capability
bounding set for systemd-logind. As CAP_SYS_ADMIN actually allows a huge
set of actions, this mostly renders the restriction-set useless. Anyway,
patches are already pending to reduce the restriction on the kernel side.
But these won't really make it into any stable-release so for now we're
stuck with CAP_SYS_ADMIN.

With the advent of systemd --user sessions, it's become very interesting to spawn X as a user unit, as well as accompanying processes that may have previously been in a .xinitrc/.xsession, or even just to replace a collection of XDG/GDM/KDM/etc session files with independent systemd --user units. The simplest case here would be to login on a tty, with the traditional /usr/sbin/login "login manager".
However, systemd --user (spawned by user@.service) is at the top level of the slice for the user, and does not inherit any environment variables from the login process. Given the number of common applications which rely on SHELL being set in the environment, it seems like the cleanest way to provide this variable is to set it to %s in the user@.service.
Ideally in the long-term, applications which rely on SHELL being set should be fixed to just grab it from getpwnam() or similar, but until that becomes more common, I propose this simple change to make user sessions a little bit nicer out of the box.

This service was merged with systemd-random-seed-save.service in
c35b956d34bbb8bb208e49e45de2c103ca11911c.

ControlGroup= is obsolete, so let's drop it from the default nspawn unit
file.

systemd-logind will start user@.service. user@.service unit uses
PAM with service name 'systemd-user' to perform account and session
managment tasks. Previously, the name was 'systemd-shared', it is
now changed to 'systemd-user'.
Most PAM installations use one common setup for different callers.
Based on a quick poll, distributions fall into two camps: those that
have system-auth (Redhat, Fedora, CentOS, Arch, Gentoo, Mageia,
Mandriva), and those that have common-auth (Debian, Ubuntu, OpenSUSE).
Distributions that have system-auth have just one configuration file
that contains auth, password, account, and session blocks, and
distributions that have common-auth also have common-session,
common-password, and common-account. It is thus impossible to use one
configuration file which would work for everybody. systemd-user now
refers to system-auth, because it seems that the approach with one
file is more popular and also easier, so let's follow that.

This means we can use default dependencies on mount units without having to get them automatically
ordered before the filesystem targets.

Fixes errors seen when booting VMs on QEMU like
systemd[1]: kmod-static-nodes.service: main process exited, code=exited, status=203/EXEC
systemd[1]: Failed to start Create list of required static device nodes for the current kernel.
systemd[1]: Unit kmod-static-nodes.service entered failed state.
Make sure that mknod capability is available

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=998122.
Note: upstream kmod has a patch [1] to exit with a warning if
modules.devname is missing. We could use new %v specifier to make this
service conditional on the existence of this file, but this could
mask a kernel installation error, hence we should let kmod run
even if the file doesn't exist.

Without this, fsck would be re-run if any other service which pulls
in a target requiring one of the mounts was started after fsck was done
but before the initial transaction was done.

This makes the description string of the backlight service a bit nicer.

As many laptops don't save/restore screen brightness across reboots,
let's do this in systemd with a minimal tool, that restores the
brightness as early as possible, and saves it as late as possible. This
will cover consoles and graphical logins, but graphical desktops should
do their own per-user stuff probably.
This only touches firmware brightness controls for now.

This is useful to fake session ends for processes like shells.

which pulls in basic.target, was started after setup-dev was finished

dracut uses systemd in the initramfs and does not write these files
anymore.
The state of the root fsck is serialized.

Since a long while we can use "systemctl enable getty@tty1.service"
which does the right thing, so there's no need to abuse Alias=
for installation.

As of kmod v14, it is possible to export the static node information from
/lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format.
Use this functionality to let systemd-tmpfilesd create the static device nodes
at boot, and drop the functionality from systemd-udevd.
As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev:
* the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw)
* ordering before local-fs-pre.target (see 89d09e1b5c65a2d97840f682e0932c8bb499f166)

We should probably work around it, until it is sorted out.

Embedded folks don't need the machine registration stuff, hence it's
nice to make this optional. Also, I'd expect that machinectl will grow
additional commands quickly, for example to join existing containers and
suchlike, hence it's better keeping that separate from loginctl.
|
|
In order to prepare things for the single-writer cgroup scheme, let's
make logind use systemd's own primitives for cgroup management.
Every login user now gets his own private slice unit, in which his sessions
live in a scope unit each. Also, add user@$UID.service to the same
slice, and implicitly start it on first login.
|
|
Replace the very generic cgroup hookup with a much simpler one. With
this change only the high-level cgroup settings remain, the ability to
set arbitrary cgroup attributes is removed, so is support for adding
units to arbitrary cgroup controllers or setting arbitrary paths for
them (especially paths that are different for the various controllers).
This also introduces a new -.slice root slice, that is the parent of
system.slice and friends. This enables easy admin configuration of
root-level cgrouo properties.
This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in
/dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is
turned off by DevicePolicy=).

- This changes all logind cgroup objects to use slice objects rather
than fixed croup locations.
- logind can now collect minimal information about running
VMs/containers. As fixed cgroup locations can no longer be used we
need an entity that keeps track of machine cgroups in whatever slice
they might be located. Since logind already keeps track of users,
sessions and seats this is a trivial addition.
- nspawn will now register with logind and pass various bits of metadata
along. A new option "--slice=" has been added to place the container
in a specific slice.
- loginctl gained commands to list, introspect and terminate machines.
- user.slice and machine.slice will now be pulled in by logind.service,
since only logind.service requires this slice.

* baud rate is optional and unnecessary for virtual terminals
* term type is optional (default is 'linux' for virtual terminals
and 'vt102' for serial lines)
* long options are more user-friendly
... all this is supported since util-linux v2.20 (Aug 2011).

With this change systemd-update-utmp-shutdown.service is replaced by
systemd-update-utmp.service which is started at boot and stays around
until shutdown. This allows us to properly order the unit against both
/var/log and auditd.

That way ordering it with MountsRequiredFor= works properly, as this no
longer results in mount units start requests to be added to the shutdown
transaction that conflict with stop requests for the same unit.
