Hi all -- I just installed my first btrfs-based linux tonight, and I must say it gives me a very warm feeling! Congratulations on all your hard work and your fine product.
I administer laptops for a small school, and we want to implement what Deep Freeze (http://www.faronics.com/enterprise/deep-freeze) does for Windows -- no matter what a student does after they log in, when they reboot it is all forgotten and the computer has returned to a standard state. I would think this would be a FAQ, but I have searched the web and mailing list for the past couple of hours. Of course it's easy to mount a snapshot, but then if students make changes the snapshot changes. The plan that occurs to me is to make a snapshot of the system in the state that I want to always boot. Then, I would rewrite the init script in the initrd to (a) delete any old tmp copy of the snapshot; (b) copy the static snapshot to a tmp copy; (c) mount the tmp copy. That's a little harder than I was hoping to work -- is there an easier way to get this functionality? I have a small ext4 boot partition containing grub, vmlinuz and initramfs. Everything else is in a big btrfs root partition. I am running Fedora 14, with Fedora-patched linux 2.6.35. I could upgrade if necessary.
