If you: * resize the (unused) root-c partition (use the chrx script to do it for you, if you like) * mount it somewhere under /mnt/stateful_partition * use that for your chroots, etc Then you can safely use chromeos in dev mode, and not worry about the "deadly spacebar at bootup" problem. Pressing the spacebar takes you out of dev mode, which will involve rewriting the contents of the rootfs partition currently in use. It will NOT repartition the entire drive, so your separate partition will be safe. Just revert back to dev mode, and you'll see its still there. Or ... put everything on a mini usb stick :)
