4.2 Request - readonly ROOT filesystem

[Joseph S. D. Yao]

The Air Force Data Services Centre (AFDSC) at the US Pentagon long
ago set up their system like this, so that they could distribute a
version of UNIX that they could also maintain.  It was on one of
the early UNIX Users' Group software distribution tapes.  I believe
that they did move a bunch of stuff out of /etc.  I'm not sure.
I know the current net address of one of the implementors, but am
reluctant to broadcast it without his permission.  Would someone at
MITRE ask Walt if he minds saying a word about this?
