8d41a963d6 machine-id: be nice and generate compliant v4 UUIDs 
Newly generated machine IDs now qualify as randomized v4 UUIds. This is
trivial to do and hopefully increases adoption of the ID for various
purposes.

2b583ce657 use /run instead of /dev/.run 
Instead of the /dev/.run trick we have currently implemented, we decided
to move the early-boot runtime dir to /run.

An existing /var/run directory is bind-mounted to /run. If /var/run is
already a symlink, no action is taken.

An existing /var/lock directory is bind-mounted to /run/lock.
If /var/lock is already a symlink, no action is taken.

To implement the directory vs. symlink logic, we have a:
  ConditionPathIsDirectory=
now, which is used in the mount units.

Skipped mount unit in case of symlink:
  $ systemctl status var-run.mount
  var-run.mount - Runtime Directory
    Loaded: loaded (/lib/systemd/system/var-run.mount)
    Active: inactive (dead)
            start condition failed at Fri, 25 Mar 2011 04:51:41 +0100; 6min ago
     Where: /var/run
      What: /run
    CGroup: name=systemd:/system/var-run.mount

The systemd rpm needs to make sure to add something like:
  %pre
  mkdir -p -m0755 /run >/dev/null 2>&1 || :
or it needs to be added to filesystem.rpm.

Udev -git already uses /run if that exists, and is writable at bootup.
Otherwise it falls back to the current /dev/.udev.

Dracut and plymouth need to be adopted to switch from /dev/.run to run
too.

Cheers,
Kay

d7ccca2e3f main: introduce /etc/machine-id 
This is supposed to play the same roles /var/lib/dbus/machine-id,
however fixes a couple of problems:

- It is available during early boot since it is stored in /etc

- Removes the ID from the D-Bus context and moves it into a system
  context, thus hopefully lowering hesitation by people to use it.

- It is generated at installation time. If the file is empty at boot
  time it will be mounted over with a randomly generated ID, which is
  not saved to disk. This is useful to support state-less machines with
  no transient or writable /etc configuration.
