Comment 7 for bug 1215386

You are correct, the error I'm seeing comes from the fact that I have this line on the container's fstab:

  proc /var/lib/lxc/test/rootfs/proc proc ro,nodev,noexec,nosuid 0 0

That is, I was trying to mount /proc as read-only in the container. This works for me in 12.04 but not in 13.04.
