    The best I came up with, was copying the failsafe image, mounting as an FS, putting in new versions of kernel and driver files from the running system, and packaging that back. Details in my comments on Alex's blog where he announced Firefly.

    Yes, it is a rather perverse way, and a more straightforward, maintained (e.g. what if other drivers become needed?) and automated one would be welcome ;)
