Ultrix 1.2:
-rwxr-xr-x  1 root     system       9216 Feb 19  1986 /bin/mkdir
-rwxr-xr-x  1 root     system       9216 Feb 19  1986 /bin/rmdir

Sun 3.2:
-rwxr-xr-x  1 root     staff       16388 Sep 15  1986 /bin/mkdir
-rwxr-xr-x  1 root     staff       16384 Sep 15  1986 /bin/rmdir

So why does SysV need them suid and not 4bsd?
