I think you are totally missing the point that Theo just made. Marking partitions as read-only is useful, when and only when appropriate. I have: /var/www/var /home /home/user1 /home/user2 /usr/local
all marked as read-only. Why, because when the power fails, no data is lost and I'm quickly back up with minimal fsck'ing. When user1 or user2 logs in, There is a big message telling them to mount their partition rw and right before logging out or shutting down, to mark as ro. When the lights start to flicker, Ctrl-Alt-Backspace slams you out of X and ro alias slams that partition safe much faster than shutdown. This has saved my ass twice now. Backup your data and re-install that snapshot if you lose /usr, etc. Works great for me. Many times. You are backing up etc and root, right? Chris
