>Description:
	

I was following the notes in Section 16.11.8.2 After the Disaster of the
handbook at
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/backup-basics.html
to repartition a server running 5-STABLE.

I ran into problems with running restore since the root partition (and thus
the /tmp dir) has only a few hundred blocks free when you boot from the fixit
CD.  Restore will quickly fill up the space and the restore will fail.

>How-To-Repeat:
	

boot to fixit floppy and run 'restore' on a good sized partition.  the dump
file was about 200k blocks.

>Fix:

	

set environment variable TMPDIR to some suitably large place or mount a
ramdisk for /tmp.  I'm not sure what the instructions to do the latter would
be, as I was lucky enough to have a suitable place to set TMPDIR to.

Please add some commentary on setting TMPDIR and/or mounting a reasonably
large /tmp via MFS to let restore succeed.
