	Yes, that's why I started a discussion on it ;-)

	I'm not exactly sure the best way to implement this in the
	package system.

	From a functionality point of view, I think that the rc.d
	script should be copied to /etc/rc.d at some stage of `make
	install', as long as the file doesn't already exist. If it
	does exist, bitch a lot. If we go separate configs per file
	similar rules for the config file should apply.

	Now, if the best way to impleement this is to first put the
	script into /usr/pkg/etc/rc.d, and then copy it postinstall
	if the /etc/rc.d/foo doesn't exist, then that's fine by me.
	I suppose that has the benefit that you always have a copy of
	the `virgin' script around too...

	I'm not sure exactly how to do it; you're the package gurus ;-)
	I was trying to highlight the functionality, which I had
	determined by talking to a few people about various
	requirements. E.g, some people wrote that they didn't want a
	package on by default because they built packages, but a lot
	of people have also expressed the desire to make things easier
	for users who expect to be able to
		* extract pkgsrc
		* cd www/apache
		* make install
	and have it just work by starting up at next boot.

More food for thought :-)
