512MB PII system, worked under 1.3_ALPHA 'okay' but I dunno how it was
installed....

Has one disk (only- wd0). No matter what I've put on that disk (I've
stopped with 'raw' wd0 with wd0a being a 4.2BSD) sysinst dies on me
after the screen:

	I found only one disk, wd0. Therefore I assume you want to install
	NetBSD on it.

whereupon I select a (for Yes) and I get


	uid 0 on /: file system full
	/: write failed, file system is full
	Segmentation fault

and I get a shell prompt. Clearly sysinst exited with some bogus pointer
(and tried to dump core but couldn't).

Any pointers (cough) for me to try?
