The mount point directory /sys/kernel/config is only created after the
module is loaded, hence there's little value in having this an automount
unit: the runtime penalty for mounting an autofs here should be the same
as for a real mount.
Return 0 only if the PID was really loaded. If no PIDFile= is defined,
return -ENOENT.
Only one caller cares about the return value of this function and this
change makes the usage nicer.
When some forking daemons receive a SIGHUP, they re-execute themselves
and consequently change to a new main PID. As long as they update the
PID file in the right order (before exiting the old PID), we can detect
that and avoid killing them.
ConditionPathExists and ConditionFileIsExecutable follow symlinks.
ConditionPathIsDirectory does not follow symlinks.
(XXX: is this actually the desired behavior?)
With output of services going to syslog by default now, the rescue shell
units need to direct their output to tty explicitly.
Specify stderr too, just in case.
The logic never worked since reading from the boot console is useless
when a service is started after boot. Hence drop this half-baked code,
since we now have a place document incompatibilities like this.

It was noted on IRC that the current layout is not necessarily the
easiest to parse by humans. I personnally struggled understanding it the
first time I read it.
Hopefully, this change makes it easier to understand.
Note: I only reformatted the information that was already present in the
documentation, I didn't add anything.
