Nobody has mentioned the environment variables set up automatically
in Domain/OS processes:

SYSTYPE=bsd4.3
ISP=m68k
TERM=apollo_1280_bw
NODETYPE=DN4000
NODEID=14E4F

SYSTYPE,  ISP, and NODETYPE can tell you a lot about what kind of 
machine you're running on.  Avoid depending on TERM, because a lot
of the newer display devices just use the value "apollo."

Beware if you hardcode dependencies on NODETYPE -- sometimes 
beta and early bird versions of new hardware have strange nodetype
values like "DNEXYZ" (which later became "DN2500").
