Note, it's possible that NFS umount/remount will not work in some
cases, because not all necessary mount options are in /proc/mounts.
I hope this issue will be fixed before F15 release.
I forgot one disadvantage -- for read-only bind mounts is necessary
to use "bind" mount options for the remount command.
systems with mtab:
mount --bind /foo /foo
mount -o remount,ro /foo
systems without mtab:
mount --bind /foo /foo
mount -o remount,bind,ro /foo
