While it'll likely cause problems at some point, I think the lxc-ubuntu
template should pin the versions of those packages.  There's probably
a more maintainable way of handling this - like either having our own
post-upgrade hooks which undo badness from those packages, or just
keep a set of lxc package archives.

Search the archives for udev, someone had this problem before and
documented the fix.
