Code review comment for lp:~lbssousa/lightdm/guest-account-union-mount-skel

Robert, could you please update this merge with a last-minute patch to add a -r (read-only option) for bindfs mounts? Consider also including packages "bindfs" and "linux-image>=3.18 (to ensure overlayfs is available) | aufs-tools" in "Suggests:" field for lightdm package.
