It would be really handy to have a place to hook in overrides for the system defaults
for daemons to be enabled, and their flags. Vendors who ship products based around
FreeBSD typically have to enable a bunch of product specific overrides to the daemons
that need to be run.
Rather than putting all these settings in /etc/rc.conf, which might also have a
bunch of per-machine settings. Standardize this by adding a /etc/defaults/vendor.conf settings file.
