Re: cgmanager and #757348

[Serge Hallyn <serge.hallyn@ubuntu.com>]

Hi,

those two patches are fixups after the following patch:

https://github.com/lxc/cgmanager/commit/a08d1c038c8457cda1b5d85c4d628595157812c1

startup: pivot into a mostly-empty new root

which is the one that really fixed the issue.  Backporting these
should be no big deal.  Please let me know if you hit any issues,
I'm up against some deadlines today but if needed I can come up
with a debdiff over the weekend.
