Before it was a huge file with more than 700 lines. No code changes were
made except for changing imports and class names where needed. In the

In revision 459 I added a bug in the make dist rule in the sense that
the archive will include *all* of test/data directory, including the
.svn directory if it exists.

This patch fixes that problem and adds a distcheck hook that tests for
such errors in the future (files/directories matching the .svn and .git
patterns).

It also fixes a typo in the NEWS file.

(http://autoconf-archive.cryp.to)

It fixes the main Makefile.am to create $localstatedir/{lib,log}/ganeti.
It fixes the testing Makefile.am after the rename fake_config.py ->
mocks.py.  It strips the output of "ip link show" to have a nicer output
if the master netdev does not exist.
