    <p>Sebastian,</p>
    <p>Hagfish is a custom loader for the Barrelfish CPU driver, which
      operates under a few unusual assumptions: Mainly, the CPU driver
      (kernel) itself is not self-relocating, but relies on the
      bootloader (Hagfish) to do the relocation for it.</p>
    <p>It would definitely be possible to modify Hagfish to load an
      arbitrary ELF, however.  You'd have to make a few changes in the
      relocation code to not look for Barrelfish-specific segments and
      so on, but there's nothing particularly weird or non-standard
      about it.</p>
    <p>Hagfish is pretty static, and doesn't change much from version to
      version.  We'll update the repository shortly (which we should
      have done together with the release).  Feel free to ask more
      specific questions if you decide to use it - we're happy to help.</p>
