From ed(1):
FILES
     /tmp/ed.*  buffer file

Solution:
mdconfig -a -t swap -s 64m -o reserve -u 0
newfs -U /dev/md0
mount /dev/md0 /tmp
chmod 1777 /tmp

Also, there's /rescue/vi (since 7.0 I believe), which will complain 
about /var/tmp/vi.recover, which you can a) ignore or b) use above procedure 
with -u 1 to create /var/tmp.

Problem with today's modular software: they start with the modules
    and never get to the software part.
