fstab only contains the actual mount point, /media/cdrom0, not the
symlink to it at /cdrom.

I'm not sure whether you mean mtab here. /etc/fstab is a static file so
there's no way of telling from that whether something is mounted. I
looked at ROX's code for checking whether a directory is mounted a while
back, because I ripped it off for something else: it checks whether the
directory is on a different device from its parent (or has the same
inode - I'm not really sure why). I think the problem is that it just
isn't receiving/responding to whatever signal it might get to indicate
that the mount points have changed. It could probably use the same
method it uses to detect when the contents of a directory have changed.
