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.

ecde7065f7 units: rebuild /etc/passwd, the udev hwdb and the journal catalog files on boot
Only when necessary of course, nicely guarded with the new
ConditionNeedsUpdate= condition we added.

db62b5b37e units: remove conditions from systemd-tmpfiles-setup
There's no point in conditionalizing systemd-tmpfiles at boot, since we
ship tmpfiles snippets ourselves, hence they will always trigger anyway.

Also, there's no reason to pull in local-fs.target from the service,
hence drop that.

8181565124 tmpfiles: rename --unsafe to --boot
As suggested by Kay, it is better to describe what is done,
not what might happen.

c4708f1323 tmpfiles: introduce the concept of unsafe operations
Various operations done by systemd-tmpfiles may only be safely done at
boot (e.g. removal of X lockfiles in /tmp, creation of /run/nologin).
Other operations may be done at any point in time (e.g. setting the
ownership on /{run,var}/log/journal). This distinction is largely
orthogonal to the type of operation.

A new switch --unsafe is added, and operations which should only be
executed during bootup are marked with an exclamation mark in the
configuration files. systemd-tmpfiles.service is modified to use this
switch, and guards are added so it is hard to re-start it by mistake.

If we install a new version of systemd, we actually want to enforce
some changes to tmpfiles configuration immediately. This should now be
possible to do safely, so distribution packages can be modified to
execute the "safe" subset at package installation time.

/run/nologin creation is split out into a separate service, to make it
easy to override.

ef72c1f06e man,units: tmpfiles.d(5) cleanup
Condition for /lib (necessary for split /usr) was missing from the unit.

Some changes which were done in tmpfiles.d(5) were not carried over to
systemd-tmpfiles(1).

Also use markup where possible.

c35b956d34 units: rework systemd-random-seed-{load,save}.service to be a single service
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.

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.
