Ouch !!! Do you by any chance have a worklog of this setup Jason ? I'd be
willing to setup and test this myself. BBBlfs is pretty interesting, but I
was under the impression this was an Android only thing - As per the GSoC
project . . . granted, Android is (sort of ) Linux too . . . I did find the
github project page, the instructions seem complete, but I was more
interested in knowing what you had for a run script off the udev rule
mentioned above.
