This is your site policy, and is not necessary how everyone runs their 
machines. I, for one, take it that each drive that is added to a machine 
is going to be empty - its trivial to remaster a machine on the fly with 
tools like cobbler+koan and use puppet to manage the machine, Capistrano 
to manage app rollout.

The concern you raised was about network interfaces not coming up in a 
predictable manner when people move from centos-4 to centos-5, the 
answer to which is, use hwaddr's in your network scripts.
