We use a local variant of the F11-XO1 images by Stephen Parrish, signed
with the deployment keys.

The procedure for each laptop is:

(1) backup the lease.sig to a USB stick
    ("cp /security/lease.sig /media/PENDRIVE")

(2) reboot while pressing all 4 game keys

(3) wait for about 3 minutes to load the image

(4) boot with the USB stick still fitted to re-activate the
    laptop

If your laptops are unlocked, you can save steps (1) and (4) and you
don't need a signed build. The procedure would become:

(1) press ESC on boot to get to the ok prompt

(2) type "copy-nand u:\osNN.img"

(3) wait for about 3 minutes to load the image

See my reply to Bert in this same thread for some considerations about
Journal backup/restore.

The scripts I mention in that post are available from our public
repository, but atm I can't reach the office to retrieve the link. 

They're really crude scripts, no big deal. It would be really cool if
someone could work on a bootable USB stick which would automatically
perform full backups and restores. Not only it would save time, it would
make students and teachers more autonomous from us techies.
