I haven't figured out the proper way myself, but the problem is that the 
defaults you set at top, override the rc.conf variables, because they don't 
exist yet. What I do is move load_rc_config before setting defaults. General 
order becomes:
name=foo
rcvar=`set_rcvar`
load_rc_config ${name}
foo_default=${foo_default:-"default value"}
run_rc_command "$1"

Seems to work, maybe I'll figure out the proper way once I finish reading:
