There is something to be said for fresh installs,
and something to be said for upgrades.
(The main advantage of upgrades is that you do not have to re-enter
information about your system.)

In my experience, upgrades and installs of Fedora
are both completely "stable".

That verges on paranoia, in my view.
I'm not sure what a "bot network" is,
but I would have thought it was fairly easy to construct a firewall
which prevents your computer being taken over.

How do you know which files in /etc to copy to your new system?

Hi again Timothy Murphy!

The "bots" mentioned are networks of "zombie" computers created by
obtaining the ability to install your applications on the computer
(root kits an examble).  The ones reviewed shut down the computers of
a local hospital (DOS even for the bots trying to find more prey!),
thousands of military computers, a CA school system etc..  The ones
who control the "bots" can make them do basically whatever.

I will try to remember to send you a link (little time now).

I copy such things as /etc for reference.  I would only use a file
from an old /etc to tell me how to make one in my new /etc work.
