Comparative is using mount points (e.g. /mnt/redhat) which are not in fstab which will be gone on the first reboot and any further attempts to access them will fail. We will need either to make these mounts persistent (and delete them afterwards) or check and create them in every test accessing them. See Bug 621179.

This is actually done (you can find rlMountAllCommon at the beginning of the pseudo-tests), so if those mounts weren't accessible, it was for some other reason. But RCW should be deprecated by the Beaker ability to provide erratified boxes (in our reqs for beaker) anyways.
Assuming this is no longer an issue.
