Seriously. Wouldn't it be a much more reliable path, and consume much

Briefly, No.
Hi Timothy,
By what you write later, I don't think a full "no" is correct. Your
solution,
which I approve and sometimes do myself, is perfectly compatible with
mine,
if not the same thing in practice.
What I REALLY wanted to say in my first email (and yes, I should have
said it
better!) is that upgrades can be much more painful and slow than
installing
from scratch and re-configuring the resulting new environment.
Regardless of
whether the new install is done on the same disk/partition as the old
one
(i.e actually erasing it, as I wrote) or on another one.
But of course in both cases, even if I didn't write it explicitly, it
would
be stupid not to copy/reuse as-is, whenever possible, the configuration
files
from the old installation.

Surely we all have enough space on our disks nowadays
to create a new partition, and install the new version there?
This gives you a safety net, as you can go back to the old version,
if things don't work out.
Also, you can copy /etc/hosts and similar (with some care)
from the old version.
I did this recently, with an ancient computer (Thinkpad T43),
which I'd left in another house for a couple of years,
and which was running an old version of Fedora, I think Fedora-16.
I was quite surprised it still seems to work fine -
the internal speaker is much louder than any of its successors,
so it's better for listening to the news, etc.
