The bluetooth checks are done on /etc/rc.conf through eval. Given that
/etc/rc.conf inherits its settings from /etc/defaults/rc.conf (see the
beginning of the file), I can't simply check whether the wannabee
powerd=NO line comes from /etc/rc.conf solely, or inherited from
/etc/defaults/rc.conf via ". /etc/defaults/rc.conf".

Have a look to a rc.conf, it will set its environment by executing
/etc/defaults/rc.conf first.

Well then, just show me how you would do that. Have a look at
rcvar_is_enabled():

http://nxr.netbsd.org/xref/src/usr.sbin/postinstall/postinstall#360

It executes /etc/rc.conf first (so that variables are set), which will
also executes /etc/defaults/rc.conf internally. Now how the script is
expected to know that "powerd=NO" came from /etc/rc.conf, and not
/etc/defaults/rc.conf?
