I have done CD installs, HDD installs and FTP installs, if you are upgrading 
in place its much of a muchness (assuming you have a stable Internet 
connection). 

The safest method of all is to install the OS to a new HDD, then bring over 
your data from the old HDD afterwards.  Its often the case that you ran out 
of space anyway and need a bigger HDD.  In this case you can at all times 
return to your pre-install state just with a HDD swap.  If you are upgrading 
to the same HDD then even if the install is a disaster, you can still install 
fresh to a new HDD, mount the old guy and recover the data... its hard to 
imagine that the install would destroy the filesystem, unless you are dumb 
enough to nuke it with fdisk during the install action.

I have upgraded RH9 -> Fedora in situ several times and not had a problem, but 
the new HDD method is guaranteed not to kill your data if you consider it 
critical.

Installing from HDD is actually less error-prone than from burnt CDs, since 
there is no possibility of burn/read errors, which are a very real factor.

William has sent out a lot of helpful advice on the list, it doesn't sound 
like a good idea to complain at him (especially when he was right).  Better 
to admire superior advice than deny it, even if it stings for a minute or 
two.
