   2 Enbedded target, similar to the stage2 target, builds upon a stage2 tarball.

   4 A stage2 tarball is unpacked, but instead
   5 of building a stage3, it emerges @system into another directory
   6 inside the stage2 system.  This way, we do not have to emerge GCC/portage
   7 into the staged system.
   8 It may sound complicated but basically it runs
