in FreeBSD, the bulk of the rc.d scripts are basically the same format,
inhaling a standardized library of functions, populating some variables,
maybe adding a few custom functions, then jumping to "main".
all largely driven off variables which have preset defaults in /etc/default/rc.conf, and over-ridden by /etc/rc.conf.
something i saw in various linux systems, which i now see moving into FreeBSD,
is the concept of the .d config directory, where the files in /etc/myapp.d are
effectively concatenated to /etc/myapp.conf.
this is quite nice from a sysadmin perspective, as you can set defaults in
/etc/myapp.conf, and then over-ride them with server/environmental specific
(and appropriately named) files in /etc/myapp.d/....
