The patch prevents read-write mounts of read-only floppies:

: orion# mount
: /dev/ad0s1a on / (ufs, NFS exported, local)
: devfs on /dev (devfs, local)
: /dev/ad0s4g on /home (ufs, NFS exported, local, soft-updates)
: /dev/ad0s4f on /usr (ufs, local, soft-updates)
: /dev/ad0s4e on /var (ufs, local, soft-updates)
:
: orion# mount -t ufs /dev/fd0 /mnt
: mount: /dev/fd0: Read-only file system
:
: orion# mount
: /dev/ad0s1a on / (ufs, NFS exported, local)
: devfs on /dev (devfs, local)
: /dev/ad0s4g on /home (ufs, NFS exported, local, soft-updates)
: /dev/ad0s4f on /usr (ufs, local, soft-updates)
: /dev/ad0s4e on /var (ufs, local, soft-updates)
