Package: lxc
Version: 1:2.0.6-1
Severity: normal

Dear Maintainer,

Since upgrading, centos6 containers fail to start.

They dont even get far enough along to get a console.

I run them with the following:

lxc-start -l DEBUG -F -n blah -o /tmp/lxc.log

I am guessing that upstart is doing something crappy and lxc is now carefull enough to notice?
