Nope, much older. It was a BSDism -- Cory Hall 11/70 actually (V6
originally) - wnj probably, but it may have been somebody like Asa
Romberger or Bob Kriddle who were the admins. VAXen distributions picked
it up and Sun got it from there.
Also, I don't think it's been
mentioned, but there's the setuid bit on
directories - otherwise known as the sticky bit. When set, even if you
have rights to "write" the directory (meaning, delete files), you can't
delete those owned by other users. Useful for /tmp
Also a SunOS invention, IIRC.
