Interestingly this only happens with lxc-start-ephemeral, i. e. with an aufs/overlayfs overlay. If I use lxc-clone/lxc-start, this upgrade works perfectly well. The EXDEV happens with both aufs and overlayfs though.
Tobiasz: What kind of upgrade did you do when you encountered this? Was this an LXC container or a physical machine?
