On FreeBSD /bin/unlink is a link to /bin/rm
/*
* Test for the special case where the utility is called as

* simplified.
*/
if ((p = strrchr(argv[0], '/')) == NULL)
p = argv[0];
else
++p;
if (strcmp(p, "unlink") == 0) {
while (getopt(argc, argv, "") != -1)
usage();
argc -= optind;
argv += optind;
if (argc != 1)
usage();
rm_file(&argv[0]);

Hmm the code in rm does more than a simple unlink(2).
