[ltp] HELP..Installing RedHad 7.2 on a Thinkpad 600E

[Tod Harter]

I'm saying that upgrades in general are not 100% reliable, and personally I 
always reinstall. Doing a piecewise upgrade on your own is as I said likely 
to be a really annoying process at best... I haven't played with RH in a 
while, but I assume they have a tool somewhere to give you a list of 
installed packages, compare it to a list somewhere else, and do an rpm 
--upgrade on any that are newer. The question then becomes whether or not 
thats enough. Many subsystems create files here and there that aren't 
strictly speaking managed by any package. Also the specific order of package 
installation can be fairly significant, and you can't guarantee that you can 
get that right. Some packages even behave differently depending on the 
presence/absence or versions of dependencies. 

Overall your usually best off reinstalling. If you have stuff on your machine 
you want to keep you can move it to /home (if thats a seperate partition) and 
just choose not to reformat that partition, in which case your files will be 
there. Most of the time thats the best strategy I think.
