Your config includes /usr/share/lxc/config/common.conf, not
/usr/share/lxc/config/ubuntu.common.conf .

If you created a configuration using 'lxc-create', and that turned
out not forward-compatible, then I would consider that a bug.  And
given the churn there has been recently I wouldn't be surprised if
there were such cases.  However, if your config was hand-created,
then while I still consider this unfortunate, the newly increased
commonality between config layouts for different distributions is
worthwhile.

I wonder whether we can come up with a versioning/backup scheme for
configuration files to prevent this sort of thing in the future.
The trick is that for most containers we do want to take updated
configuration files, as that's the whole point.

Perhaps what we need, the real bug here, is better documentation
of what the *.$distro.* and *.common.* really mean and what a user
is safe to use.

  It seems a fairly recent update to LXC has caused this.  This is a
