Please remove /etc/mtab from the default /etc/rwtab shipped in initscripts. Due to Bug #214891 /etc/mtab in rwtab was never useful. Until that bug is fixed or we have union mounts, symlinking /etc/mtab to /proc/mounts is the standard for read-only roots. With /etc/mtab in rwtab an ugly error message happens during boot.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
