Actually - pathname *is* the fixed mapping.  The filename:pathname scheme
is to bridge the gap between a real world filename (like say, filo.elf),
and the mapping within the LAR that LinuxBIOS understands (normal/payload).

Sure - we can use the term filetype if you want.  Pathname is a little
bit more descriptive, since the LAR can technically hold arbitrary blobs
of data - what ever the loader needs ('vsa') comes to mind.

But its just a term - I would be happy to use filetype if thats a better
way to think about these things.
