All it takes is one extra line at the top of the scipts to source
/usr/pkg/etc/rc.d as well... rc.subr doesn't depend on the control
variables being set in rc.conf.
My current xfstt reads:
# PROVIDE: xfstt
# REQUIRE: DAEMON LOGIN
# BEFORE: xdm
command_args="& sleep 2"
...and /usr/pkg/etc/rc.conf is a mundane:
xfstt=YES xfstt_flags="" # X11 True Type font
(I'd have it sourcing /usr/pkg/etc/rc.conf if there were defaults, but
this is homebrewed rather than from pkgsrc, so there aren't)
That's one extra file (per system) and one extra line (per package
script)... what's so bad about it?

No, no, no... my script uses configuration from /usr/pkg, but some people
said that people using NFS-shared /usr/pkg (in a cluster for
example) might want per-machine configuration, so I just demonstrated that
***/usr/pkg/etc/rc.conf*** could be written to have conditional code based
on hostname, source files in /etc, etc. in that special case. The
/etc/rc.d scripts stay unchanged!

The example script I gave before was written without a nearby NetBSD box
to look up the right names of variables on :-)
The example I've copied out above is what I'm using right now on my
laptop. The rc.d scripts from packages live in /etc/rc.d, are
rcorder-marked to not be run until after /usr/pkg is mounted, and have
just one extra line added to them to pick up the configuration from
/usr/pkg/etc/rc.conf. I haven't thought about making
/usr/pkg/etc/rc.conf.d/ - I didn't know that existed until recently :-)
