``All of that work'' usually consist of three commands:
pkg_add (or make install)
Which corresponds exactly to the three actions I want to perform:
- install package
- enable server
- start server
I do *not* want to have to do any more, or make any of the steps
more complicated. And, with the exception of installing, this is
exactly what I do to enable a server that is part of the base system.

It is also reasonable that the servers installed via pkgsrc need to
be explicitly enabled: as others and I have noted, there are packages
that install more than just a server. Some install two or more
servers, some install a server and a client (or client library).
Simply because I need part of that package (and thus install it),
doesn't mean I want all of it's servers running.

No, that is *exactly* the issue! Servers in the base system and
servers from pkgsrc should be enabled in the same way.

Because some program needs the cups client libraries?

No, it's a not quite so simple matter of interface design: How do I
specify which of the possibly multiple servers the package provides I
want to start? We already have a method to specify which servers to
start (edit rc.d), why invent a new one?

True. Which leaves us two ways of dealing with it: either place
pkgsrc rc.d scripts on the root file system, or enable the rc
subsystem to recalculate the order after reading in the additional
rc.d scripts. Both are fine with me.

I'd prefer that we discuss what is wanted and then implement it.
And yes, I'm willing to work on it.
