Ah ok, I guess I missed that. The qa document says there is an automagic
dependency if the builder can't turn this off. But, you are asying that
the builder can turn it off with the --without option.

In that case, the dependency is not automagic.

This is another topic I may bring up at some point, if you are using
systemd, etc, and openrc is not even installed on your system, do you
need /etc/init.d at all? Once openrc goes stable, I might bring that up
for discussion.

heh, actually I like this idea also. :-)
