Well the 
ftp://releng.netbsd.org/pub/NetBSD-daily/netbsd-2-0/200410010000/vax/installation/bootfs/boot.fs 
(cat /kern/version says: NetBSD 2.0_RC1 (INSTALL) #0: Mon Oct 4 ...) boots 
properly to sysinst :)
The 
ftp://releng.netbsd.org/pub/NetBSD-daily/netbsd-1-6/200407120000/vax/installation/bootfs/boot.fs 
has a broken sysinst; but it does manage to drop into a shell.

Oh well, guess I can test the RC (or just wait till 2.0 is released).
