[Discuss] Issuing the 'sync' command more than once (and a tangent on how not to run a high-tech company)

[Jack Coats]

It may have been folk-lore, but the 'standard procedure' where I
worked, before shutting down a server on purpose, was, from root,
issue 3 commands separately when we wanted an orderly shutdown, but it
was 'urgent'.

   sync
   sync
   halt

I am sure there is some basis in history that had a basis in fact at
the time.  Even if the 'fact' was based on 'observation' rather than
reality.
