I don't think this is a major problem to be honest.

The issue I had back in January is that the behaviour changed with an 
upgrade to 10.1 from 8.something as the interaction with devd wasn't 
well known.

I don't know how this can be dealt with unless we have a load of 
special-cases that log warnings when, for example, forwarding is enabled 
in sysctl.conf but there isn't a gateway_enable in rc.conf.  That sounds 
like a messy solution to be honest.
