That's not the statement to which you were replying.
"the packaging system is who manages files and keeps track of them"
This is definitely an objective, a goal, a policy, whatever the Hell you
want to call it. It does not specify where things go as it is. It only
says that the packaging system, not the admin, should keep track of
installed files regardless of their filesystem location.

Sure, but that sort of thing isn't implemented yet. And now that we've gone
from objective back down into implementation details: which is easier to
implement as a first step -- just installing the scripts in a default-off
state and standardized location, or adding a whole new tool with which no
one is familiar yet and rubs against the grain of established experience?
(See below for what I mean about "established experience".)

My desired default would be for there not to be PKG_RCD_SCRIPTS variable.
Such a change would treat rc.d files no differently from all other
configuration and support files, all of which (including rc.d scripts) can
already be turned off today using PKG_CONFIG=NO.

With what sort of users do you interact?
I'm working with the assumption that most new NetBSD and/or pkgsrc users are
actually migrants/users from other Unix-like OS's. This jives with what
I've seen of discussions on netbsd.org mail lists. Given that:

Oh, it's not subconscious. I've said it explicitly a few times.
Where I work, we have some pretty genius-level Linux and Solaris admins who
would all be caught off guard by rc.d-type scripts not appearing in a
standardized "etc"-rooted place, typically in etc/<something>.d. They may
be great at Unix-like OS's, but they are themselves na´ve about NetBSD and
I'd put money down that at least one of them would try running daemons in
/etc/rc.local using the manpage as an invocation reference, before
discovering that the third-party software startup scripts were present after
all, scuttled away in /usr/pkg/share/examples/rc.d. After all, the config
files were installed, so why wasn't the rc.d script right there with them?
This is why I see the current state of affairs to be *more* confusing than
installing the rc.d scripts by default. I'm trying to consider the audience
as somewhat Unix-like-OS knowledgeable, at least enough to know that startup
scripts live somewhere in <some_top_level_dir>/etc. (/etc, /usr/local/etc,

Oh, that's just FUD. We have config files in LOCALBASE/etc rather than
/etc; there's no reason rc.d scripts can't live there by default. That
pathname is still configurable if you want them elsewhere.

Sure, or you have to do some sort of manipulation (which is required for all
non-NetBSD platforms anyway).
Note this: I am **not** requesting that it be integrated by default into
the NetBSD-specific startup; that would indeed need to be the job of another
tool capable of knowing OS-specific differences. I only want to see the
files be installed and tracked by pkg_* by default. The easiest and most
predictable way to implement that is to follow the PKG_SYSCONFBASE-root

And we go and add unpredictability by not installing the scripts to any
active location by default. This helps things... how?
