I'd bisect :)

However, try to update to just before this commit:

    Create interp class.

    Create an interp class. Use it to separate out the different types of
    interpreters: forth and simple with function pointers rather than
    via #ifdefs.

    Obtained from: lua boot loader project
        (via lua-bootloader)
    Sponsored by: Netflix

    git-svn-id: svn+ssh://

would be a good place to start.

It's a shame we can't create zpool images with an unpriv'd user command.
Would help out the ZFS testing of the boot loader refinement.
