e.g. a lot of stuff is spread over /var and /var/lib. I do not mention
that /var should not contain any non standard directory, i.e. xen.
Additionally, there are a few directories in /var/lib used by various
stuff. I think that all of them should be moved to /var/lib/xen.
The same is in /var/run and /usr/share case. There are also other
minor issues which are worth to fix.
