      The code is:
 
         if (bootpath == NULL)
                 bp = strdup(DEFAULT_BOOTDIR "/" DEFAULT_BOOTCODE);
         else if (*bootpath == '/')
                 bp = strdup(bootpath);
         else {
                 if (asprintf(&bp, "%s/%s", DEFAULT_BOOTDIR, bootpath) < 0)
                         bp = NULL;
         }
 
 It would be easy enough to change the second part to see if the
 path starts with "." which is a common way of stopping the prepending
 of a default path.  I'm undecided if it should check for "/" anywhere
 in the path.  However, if that's what people think is best, I'm
 willing to make either change.  I checked the installboot source
 to see what it does, and it just uses the path as given.  I think
 adding a default path makes it somewhat more convenient to use.
