This is a "feature" I suppose. I don't see why mounting should be disallowed on directories that contain items (dev's, files, dir's, etc.). In fact it is quite useful. You can for example create a "stub" /etc/ dir (with fstab, stripped passwd, and so on) that contains just enough for initial boot then the system can mount say /dev/hda5 as /etc (preventing symlink attacks, partition filling issues, etc.). -Kurt Seifried
