I did a few tests (and filed a few bug reports already) and found the
following problems that need to be addressed:

* the test should be skipped for packages that are part of the base
chroot, but not essential/required - purging them fails :-)

* needs to handle packags on dependecy cycles
  - currently install deps(p) installs p, too
  - removing p removes the depcycle(p), too
  => there is an unwanted delta in the chroot

* we need another list of excludes or some other mechanism to ignore
modified logfiles that are owned by deps(p), modified by installing p
and only purged by purging deps(p), e.g. fontconfig.log
