I should have mentioned that I'm a "commandline kinda guy". I hardly use configuration GUIs (and I live in emacs 95% of the time, including now as I type this :-). If one does their system configurations with GUIs then my trick will be worthless. : I do see the advantages of a fresh install; As for installing vs. upgrading, I've been badly burned twice in the past (on Mandrake systems) and so I always do a fresh install. The main advantage for me is that I am not left wondering if the bug I'm seeing is due to a fouled upgrade or a true system bug. That assurance is worth its weight in gold to me. And since I have a nearly complete record of the changes I made on the previous system (I always forget something :-), I can just go down the list and make the same changes (or not) as I wish. I might also mention that I have lots and lots of disk on my machine. So I have room to store a previous installation in a single partition indefinately. I usually keep the previous install around (by copying /, /usr, /var, and /tmp to a single bootable partition at the end of one of my disks) for at least 4 months until I'm sure I have everything. And (of course) I have a backup of these directies on 4mm tape or DVD before I blitz them. : but there are a several advantages in the opposite direction too. I don't know of any, other than speed, but ... : I don't think anyone should say one or the other is "better". I completely agree---unless an upgrade is a known show-stopper as it was on several Mandrake releases. Dean
