    I think it would be _very_ helpful if bgfsck could be made to only run
    once. Currently, you can have the following:

    crash -> boot -> defer for bgfsck -> multiuser -> bgfsck -> crash

    (loop until manual intervention)

    ... this happens when bgfsck can't fix something. I'd like to see:

    crash -> boot -> defer for bgfsck (but mark disk as having tried)
          -> multiuser -> bgfsck -> crash -> boot -> fsck in foreground
          -> multiuser

    ... but I believe this would require fsck support unless the startup
    scripts were writing to the filesystem to indicate no bgfsck.

    Dave.
