I personally don't remember the details about 4.1BSD, but UNIX 32/V and
all those all the way back to the beginning (or V5 at least :-) (and on
the ATT/USG branch all the way back from SysVr2x.), there was no
mkdir(2) system call, and /bin/mkdir was a setuid binary that did the
mknod,link,link thing....  (well it was makdir,link,link in V5 and V6)
