No, the script is rcNG _aware_. If rc.subr is not present in the two
locations where the scripts expects it to be, the script will just
behave like any other rc script. An added bonus is that you get reload,
restart, and status functions from rcNG.

I deliberately avoided this dependency for the squid ports since rcNG is
not needed for this port to work. If users want rcNG on pre-rcNG
systems, they can install the rc_subr themselves and the squid start
scripts will then use rcNG.
