Well then the current setup for local_unbound is counter to that, as it is BEFORE: NETWORKING > I think we're in an edge case here and, perhaps, a better solution might > be to have someone(tm) add in support in rc.conf to specify dependency > overrides. dns and configuration are a chicken/egg problem, not really an edge case, and a person must make a decision as to how to deal with that. > > So, perhaps you could set: > > dhcpd_after="unbound" > > Which would factor into the rcorder processing and make sure that dhcpd > starts after unbound. > > This would allow people to fine-tune things when they run into cases > like this.
