Yep

DOH! (at work this qualifies me for the "Marty McFly Award" ...)

Yep; /dev/hda1 is /boot.

/dev/hda1  /boot
/dev/hda5  /
/dev/hda6  /home
/dev/hda7  /usr
/dev/hda8  /var
/dev/hda10 swap

(I re-installed the original disk back; since it's the mail server, I
get no mail until it's up and running :-))

I'll try it again later tonight; it's much too nice out to sit inside
and futz with computers. :-)

Thanks; I'm sure that's probably it.
