The drive was at that point clean when it failed the first time, then I went 
back before I started the install again, used fdisk to make  a 500MB 1st 
partition, a 2gb swap next so it was on the outside fast part of the drive, 
and several more partition of various sizes cuz I like /var on its own, /root 
on its own/ and /home on its own, but when I restarted the installer and it 
put it clear at the end of the disk and kept it there regardless.  WTH is it 
with this that it also insists that /root cannot be a separate partition, but 
must be a subdir of /?  Total nonsense, that you cannot even setup a drive 
the way you want it, skip that part of the install & just go do it.

I have never figured out why you people hate fdisk so much.  Back when you 
called it disk druid or some such it was a PIMA, and while the face is now a 
lot prettier, it is just as terminally broken in its heart as ever.

Probably not and will remain so until all are using fdisk or (g)parted to do 
the disk configuration.

Perfect here.

This time it will be on a 400GB deathstar.  Distro yet TBD, but likely ubuntu.

And I just got finished half an hour ago, moving my complete amanda vtape 
archive to a new 1TB drive, so yes, you could say I'm reasonably familiar 
with such, as long as the supplied tools don't override what I want.  In the 
F8 case for both installs, they did, either resetting my choices to what they 
wanted, or by refusing to recognize them at all.

If I was to reinstall on this drive, I'd just move the end of boot/swap border 
in about a half a gig.

And all you have to do is get past the 199meg limit for /boot that the F8 
installer insisted on.  Use fdisk to set it up bigger, and the installer 
would not recognize it.
