Hmmm, interesting point. I didn't even think of that. However, if I do
that successfully, then reboot the system and it fails, there is no way
to 'undo' the installworld...right? Either way, I'm going to try it, so
I can use that experience for when I have to do a production box.

Eventually, if all else fails, I will.

The Samba box is a SMP unit, but the 4.11 is a uni-proc box. I've been
running it that way since 4.5, moving the system to new disks a few
times, and periodically more powerful boxes. I have really no reason to
upgrade this one to 5 or 6 at this point...and BTW, I always do backups.
System is on a RAID-1, with a second RAID-1 setup that gets a mirrored
copy of the primary RAID every day. Further that, I have it taped up
too. Call me paranoid, but having the backup RAID ensures that I can
just move it to new hardware and continue right on trucking.

Indeed. I just got familiar with portaudit a few weeks ago, and I find
it quite handy.
Tks for your input.
