91b684c730 rc-local: order after network.target
As suggested by Bill Nottingham: rc.local is often used for frobbing the
network.

e951701a4d rc-local: no need to check if the script is executable
rc-local.service is pulled in by a generator only if the script is
executable. No need to check again.

1567308317 add a generator to pull rc-local.service in
rc-local.service acts as an ordering barrier even if its condition is
false, because conditions are evaluated when the service is about to be
started.

To avoid the ordering barrier in a legacy-free system, add a generator
to pull rc-local.service into the transaction only if the script is
executable.

If/when we rewrite SysV compatibility into a generator, this one can become
a part of it.

1a2801529e syslog: use PassCred=yes for the /dev/log socket
Both kmsg-syslogd and the real syslog service want to receive
SCM_CREDENTIALS. With socket activation it is too late to set
SO_PASSCRED in the services.

75d3fc60f8 shutdownd: use PassCred=yes in the socket unit
Since Linux 3.2 in order to receive SCM_CREDENTIALS it is not sufficient
to set SO_PASSCRED just before recvmsg(). The option has to be already
set when the sender sends the message.

With socket activation it is too late to set the option in the service.
It must be set on the socket right from the start.

See the kernel commit:
16e57262 af_unix: dont send SCM_CREDENTIALS by default

4d8a7798e7 execute: avoid logging to closed fds
Several functions called from the "sd(EXEC)" process try to log messages
when all the file descriptors are already closed, including the logging
ones. The logging functions do not expect their fds to be closed and
they hit an assertion failure. The failure wants to be logged too,
so there is an infinite recursion, ended by a SIGSEGV.

When we close all fds, we must let log.c know about it.

c5419d4239 service: don't warn if the pidfile still exists after SIGCHLD
A service that drops its privileges may not be able to remove it when it
exits. The stale pidfile is not a problem as long as the service
carefully recognizes it on its next start.

systemd would produce a warning after the service exits:
  PID ... read from file ... does not exist. Your service or init
  script might be broken.

Silence the warning in this case. Still warn if this error is detected
when loading the pidfile after service start.

Hence, as soon as we get a notification that a cgroup is empty, delete
it. This is also nice to keep the systemd-cgls output short.

6fdae8a6a4 Add Mageia support
This patch adds support for the Mageia Linux distribution:
 http://www.mageia.org/

Mageia is a fork of Mandriva although some divergence has already occured
and thus inclusion of these changes upstream allow us to (hopefully)
migrate more rapidly to the new standard approaches systemd offers.
Indeed, we already use the preferred mechanism of OS identification via
the /etc/os-release file rather than a distro specific variation.

This patch mostly mirrors the patch added previously for Mandriva
support. In addition to those original authors, this patch was mostly
written by Dexter Morgan with help from Colin Guthrie and Eugeni Dodonov.

87e75fddbb cryptsetup-generator: avoid ordering cycle on swap

in addition to remote-fs-pre.target.

74eeab044e systemctl-completion: always invoke with --no-legend
In the case of completion for the 'restart' verb, passing the invalid

This adds a small wrapper function for systemctl which can have common
options added to it.
