Comment 3 for bug 587888

Hrm, so far not managed to reproduce this booted onto the 2.6.34-5 kernel. Below I have mounted a faked squashfs filesystem loop back on /root/RO, I have also mounted a tmpfs on RW, and then unioned them onto /root/ROOT. Basic functionality seems to work:

  # df
  [...]
  /dev/loop0 128 128 0 100% /root/RO
  tmpfs 1021280 20 1021260 1% /root/RW
  aufs 1021280 20 1021260 1% /root/ROOT
  # cat /proc/version_signature
  Ubuntu 2.6.34-5.12-generic 2.6.34
