it depends how you build them. you could do any of the following:
1: scripted cvs/http/ftp download of the needed files
2: cfengine script
3: something else mentioned on this list, I think it started with hf,
and got good reviews
4: other stuff in ports
and others, what would work for you given your existing/planed infrastructure
"We trained very hard, but it seemed that every time we were beginning to
form into teams we would be reorganized. I was to learn later in life that
we tend to meet any new situation by reorganizing, and a wonderful method it
can be for creating the illusion of progress, while producing confusion,
inefficiency and demoralization."
-Gaius Petronius, 1st Century AD
