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. - KB -- Karanbir Singh : http://www.karan.org/ : 2522219 at icq
