It indeed created some stuff there, which LXC can't see:
$ sudo ls -l /var/lib/lxc/ drwxr-xr-x 3 root root 4096 Jun 11 21:45 juju-precise-template drwxr-xr-x 3 root root 4096 Mär 11 11:04 martin-local-machine-1
I wiped /var/lib/lxc/ again and made a /var/lib/lxc → /scratch/lxc symlink, and with that it gets further. It still fails, but I'll file this as a separate bug.
