> -umount -a -n > +umount -a This may be a "umount" bug. When you unmount the root filesystem, it is actually the same as remounting it read-only because of special-case code in the kernel. Umount will attempt to change /etc/mtab to match the un-mount of root, and will fail because /etc/mtab is now on a read-only filesystem. If it fails, does it complain? If so, the "-n" flag should be added back to umount.
