lxc-clone can expand wildcards in the configuration file

[Serge Hallyn]

=====================
SRU justification:
1. impact: configuration files for cloned containers can be corrupted
2. development fix: put quotes around the variable being echoed whose contents are being expanded.
3. stable fix: same as development fix
4. test case:
 touch xyz:xyz
 lxc-create -t ubuntu -n p1
 lxc-clone -o p1 -n p2
 grep xyz /var/lib/lxc/p2/config
5. regression potential: none.
=====================

In particular, the '*:*' in the stock lxc.devices.cgroup.allow entry will be expanded if there is a *:* file in cwd.

Serge, this seems important enough to push back into precise in an SRU.

[Serge Hallyn (serge-hallyn)]

@Clint,

yes, I pushed the package to precise-proposed a few hours ago. Seems I forgot to hit 'affects release'.

[Clint Byrum (clint-fewbar)]

Just FYI on the status, 0.7.5-3ubuntu53 will progress to precise-updates tomorrow (it has only been in precise-proposed 6 days, but all bugs are verified), and then we can allow the uploaded 0.7.5-3ubuntu54 into precise-proposed.

Hello Serge, or anyone else affected,

Accepted lxc into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Serge Hallyn (serge-hallyn)]

Thanks, Martin.

Verified the bug is fixed, and the lxc test-suite passed all its tests.
