3b02170360 unit: do not order timers.target before basic.target
Since commit 19f8d03783 '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.

3898b80d40 units: define appropriate job timeout actions when boot or shutdown timeouts 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.

0fdeb6e011 units: remove RefuseManualStart from units which are always around
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.

ab9a2ef00b units: downgrade dependency on sockets.target/timers.target/paths.target by basic.target
There isn't really any need to require any targets but sysinit.target
from basic.target, so downgrade sockets.target, paths.target,
timers.target.

49dbfa7b2b units: introduce new Documentation= field and make use of it everywhere
This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.

This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.

b5e9dba8d6 unit: rename OnlyByDependency= to RefuseManualStart= and introduce RefuseManualStop=
Some unit shall never be start on user request (e.g. shutdown.target)
others never be stopped on user request (e.g. auditd.servce), hence
offer options for both.
