Keep in mind that restore uses temporary files to do its work and
these files can be fairly large for a large filesystem.

The way I do this is to newfs the partitions and then mount
hierarchically. E.g. /mnt, /mnt/var, /mnt/usr etc. It is also a
good idea to mount with the "async" mount option since it will
really speed things up. Now, since /tmp on the floppy is going
to be quiet small you need to set the TMPDIR environment variable.
Assuming that /var is of a reasonable size, and /mnt/var is mounted,
you can do
mkdir -m 1777 -p /mnt/var/tmp
export TMPDIR=/var/tmp

That way, when you do your restores you will have enough space
for the temp files.
