Yes, but following that line of thought a few steps further, a
commonized configuration and service management infrastructure lends
itself to being plugged into larger-scale management frameworks,
including multi-system management tools.
It would be (relatively) easy to layer a multi-system management tool
that could tweak any parameter or enable or disable any service on top
of SMF. It would be quite difficult to do that with a traditional
administration model.
for i in `cat hosts`
do
scp myfile ${i}:/etc/myfile
done
is simple but it's a really crummy model for multi-system management.
Heaven help you if you need to update only a single parameter in that file.
