I still can't find any documentation on this in the manpages? HA! I just
finished skimming the above thread, -F is indeed new and not in 8.1. I am
going to set up a local mirror of 7.x, 8.x and HEAD over the next week and
if I remember, I'll be sure to check it out and see if it does infact exist
in 8.2.

Sneaky ... but possibly not likely since I more then once pulled the plug
and didn't give it time to actually write anything. Either way, between your
link and Bruce's, all is well.

See, I did that the first time and it all came to a screaming halt. That's
when I started to get creative with Ian. I'm going to take a stab in the
dark and blame Seagate for kludging the disk on me. Either way, a manual
fdisk and bsdlabel did the trick, it's got to be something in sysinstall not
liking what ever was written there by gpart...
