This sounds like a nice way forward :).

This can work, rcconf then needs to be aware of what OS it is running on
since OpenBSD uses a different approach than FreeBSD and NetBSD (it does
not use the YES/NO boolean flags).

For example, enabling a service (configuring that it should start at boot)
is not possible on OpenBSD when the rcctl utility is missing because of
this. This basically means "rcconf" will not actually be able to modify
rc.conf.local on OpenBSD, but only call rc.d scripts directly to
start/stop services.

Under any circumstances, I would be happy to help out on the OpenBSD
side of things if/when this gets going.

Seems the cleanest way forward would be to remove classes from the
service module in a step-by-step fashion as new modules are ready to
take over.
