Let us know when you are said system admin faced with such a problem. Or you can listen to people who have been there and done that.

You have already said RHEL defaults with / on a lvm partition and here is someone telling you that caused problems. I highly doubt he is lying about his first hand experience. > Interesting than that many enterprise environments I see use LVM. No one is disputing that LVM is invaluable in enterprise or non-enterprise environments. But like anything there is a time and place for its use. It is not a one solution for all things, and that approach can cause problems. Clearly it has for people, otherwise documents would not exist suggesting to do things other ways. Much less first hand experiences with systems that won't boot. -- William L.
