You need a file system on the floppy disk.

For an MSDOS floppy, use

	mount -t msdos /dev/fd0 /mnt

If you care to create an ufs floppy (native BSD file system), use

	disklabel -r -w -B fd0 fd1440
	newfs -t2 -u18 -l1 -i65536 /dev/rfd0a

to (high-level) format the floppy, then

	mount /dev/fd0 /mnt

Most people prefer handling floppies using sequential IO for things
like backups.  This method doesn't have an equivalent under DOS, but
is rather similar to handling (streamer) tapes.  Hence, all the
commands applicable to tape backups apply as well.  Read the man pages
for tar(1), cpio(1), and dump(8)/restore(8) for an explanation of the
available utilities.

A simple example:

	cd /
	tar -cvf /dev/rfd0 root

to save root's home directory.  If the archive will span across
multiple floppies, try:

	cd /home
	tar -cvf /dev/rfd0 -M 1440 usershomedir

to backup /home/usershomedir onto 1.44 MB floppies.
