path_*() functions operate on "Path *p" and they do not touch PathSpec
internals directly.
pathspec_*() functions operate on "PathSpec *s". The PathSpec class will
be useful outside of path.c.
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.
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.
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

To give the administrator more hints about failures occuring in spawning
of commands than just the exit code, log the strerror.
All fds are closed, so reopen the log.

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.
The code should probably look like the statements above it.
Please verify, I just detected it using cppcheck.

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.

DefaultStandardOutput is syslog anyway. There's no reason to assume that
the administrator would want these units to be excluded when he configures
a different DefaultStandardOutput.
