The performance on my Centris 650 is not great yet, but definitely worth
seeing for yourself.  When I tried to run vipw to add myself as a user in
the passwd file, and when I tried to save the file, the machine complained
about an undefined operation, and then destroyed my passwd and shadow
password files, so that I was unable to login.  The same thing happened to
my /etc/rc file as well, when I tried to add fsck -fy to the disk checking
section.  The file got truncated on a write command and I had to replace
the file from a backup.

My machine is a Centris 650 clock-chipped to run at 33 MHz, with FPU, 8 MB
of soldered RAM, and onboard ethernet.

The newest booter is Booter1.9.4.sit.bin, at
ftp.macbsd.com/pub/NetBSD/booter, and the latest 040 kernel is also at
ftp.macbsd.com/pub/outgoing/briggs/for.scampbel.
