Thanks, Chuck.

Excepting my amd64 the computers are servers at work, so I will use
'securelevel = 0' to facilitate system upgrades while "up"- only shutting 
down now for install world.

6.2 rc1 'install world' failed on my amd64.  I can csup next month
and try out 'securelevel = 3' on that.  Probably build the world,
etc., installkernel, mergemaster and installworld could all be run
from single user then.
