If Guy Harris really said that, do I have something to surprise him.
Use a symbolic pointer to bypass it.  E.g. if you are restoring
a full /a:
	cd /a
	ln -s /tmp/restoresymtable restoresymtable
	# make sure /tmp/restoresymtable does not exist or is 0 byte.
	restore r

The restoresymtable grows in /tmp, not /a.  (This works in my 4.3BSD
VAX system and I imagine it will in others)  If your old system was
absolutely full that not even a symbolic pointer could fit, remove
lost+found after restore has started.  It is usually empty.  But this
I have not tested.
