Hi Chris,

Since all the packages sharing logilab namespace have a new upstream
version to package, it's a good time to try to fix this on all of
them.

The preinst file of logilab-astng is [1]: we already try to fix the
migration (central->support) problem but we don't remove to common
logilab/ directory.

[1] http://svn.debian.org/viewsvn/python-modules/packages/logilab-astng/trunk/debian/python-logilab-astng.preinst?view=markup

I'd like to know what would be the best solution for this (hence
-python in the loop):

- logilab-common is the lower level of logilab* packages, so we can
add conflict there with all the other logilab-* packages and then
remove logilab/ completely from its preinst
- add extra logic to all logilab* packages to check if
/usr/lib/python*/site-packages/logilab is empty and then remove it
(could there be cases where it left hanging dirs?)

I'm considering teh second solution a bit better, but I'd like to hear
from your what youi think.
