Heh, see https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/986385,
it's because lxc by default uses /mnt as the oldroot dir for pivot_root.
I'm going to change that to using a tempdir (unless Daniel has a good
reason not to), but in the meantime if you really want to mount under
/mnt/series, you can specify a custom lxc.pivotdir in the container's
config file.
