I think that opendisk should do something like this:

   if (path contains a slash) {
       use specified path, do not search in any way
   } else {
       try /dev/[r]foo
       try /dev/[r]fooX, where X is "c" or "d" depending on kern.rawpartition
   }

If the user wants to open a file in the cwd, then let the
user pass "./foo" instead of "foo" to opendisk.
