Re: Chroot and ".."

   In the really early versions of UNIX, the "dvd" command was used to
   execute "rm -r".

So now for a correction, no, `rm -r' did not use dsw (or as you call
it, dvd).  dsw needed intractive input from the front-panel on the PDP
to do anything.  The way rm -r was implemented was by calling `rm -r
*' for each subdirectory it traversed.  This had been the case ever
since the 1st edition.

Infact, what you got as a result of running dsw was a coredump which
you later executed to actually remove the file.  :-)
