Hi Suleiman,

  Patch attached: let me know if it works and I'll commit it.

  Also, you can avoid hard-coding ROOTDEVNAME by forcing the root dev
at the loader prompt:

	OK set vfs.root.mountfrom=<root spec>

  where <root spec> is what you would have typed at the mountroot>
prompt.

later,

Peter.
