 I think that opendisk(3) should do something like
 	/* assume it's a disk name, until proven otherwise */
 	if (arg contains "/") {
 		interpret it as a file name;
 		do not fall back to any other interpretation;
 	} else {
 		try various combinations of /dev/{,r}foo{,rawpart};
 		if that fails, try interpreting it as a file name;
 In this scheme, users who want "./wd2" can ask for that explicitly,
 while users who want "/dev/rwd2d" (where "d" is the raw partition) can
 ask for any of "wd2", "wd2d", or "/dev/rwd2d".
 I don't think it's un-unix-like for an interface that's intended to open
 a "disk" to interpreting its argument as a disk name in preference to a
 file name.
