Someone suggested bootdevice on IRC.  I like that one, while is not
that generic.

This is really important, I think.

This should not be the case.  Not if both tab, ls, linux, etc work
from pwd.  In that case you can cd somewhere and everything you use is
in the current dir.  And there are relative (../foo) and absolute
(/foo) paths.

This is all consistent with bash.  And it should work with all
filesystems I have implemented.  I would like this approach.  You
could even parse `.', `..' and `/' in fs.c so it becomes generic and
you don't have to pass idiotic strings to the filesystems.
