I built a new install CD, from today's 2.0beta source, and used it for 
a fresh installation.  The installation didn't work -- or rather, the 
resulting system was unbootable.  I rebooted the install CD, and ran 
installboot and fdisk to make sure I had both boot mechanisms 
installed; after that, it worked.  I'm not sure where the failure was 
-- I ran through the installation twice -- but if it helps, the first 
time I got a GRUB prompt (the disk had had Red Hat 9.0 on it).

It's possible, of course, that I mis-specified some option, but if so 
it was quite non-obvious what I did wrong.  (I specified that NetBSD 
should have the entire disk.)
