By OCAP I was thinking of things like not having global state, or at
least not having it implicitly. Something more functional. The lambda
calculus supports the OCAP model, and Guix is all about being
functional, so service management should not be any different.
Would also be nice if replacing running components was supported, a la
Erlang. Maybe steal the supervisor tree idea as well.
