Merge lp:~serge-hallyn/ubuntu-test-cases/server-lxc2 into lp:ubuntu-test-cases/server

[Serge Hallyn]

This commit will make debugging lxc testcase failures easier to debug, and *should* fix bug 1130029.

(Note - this replaces the mp for lp:~serge-hallyn/ubuntu-test-cases/server-lxc-fixapi)

don't set config to a nonexisting file by default

(no effect, since we explicitly pass in NULL)

81. By Serge Hallyn on 2013-02-26

fix syntax error (double commas)

[Stéphane Graber (stgraber)]

I'm not seeing anything obviously wrong, just a few notes:
 - I just sent a patch upstream to drop the need for autoconf pre-processing of api_test.py which should let you drop the extra build from the test.
 - Might be worth running pyflakes and pep8 against all the python scripts, I noticed some things that aren't PEP-8 compliant.
 - When installing lxc in the container, you can easily avoid the policy-rc.d + rm by simply creating /etc/init/lxc.override with "manual" as content before installing lxc. This will prevent upstart from starting the lxc job and any job depending on it.

Unfortunately that isn't yet in our package :) But I've left a comment
to remind us of that.

Awesome, that leaves PkgSetup() looking much nicer, thanks.
