as MIaB takes over the nameserver roles for my domain I’m somehow nervous about loosing access and services to my boxes. Therefore I would like to split ns2 from the MIaB box and mirror the config on another host.
Is there anybody who has tried such a setup or has it running in production?
I’ve found https://ethitter.com/2016/01/authoritative-dns-slave-nsd-debian-wheezy/ as an starting point, but it requires to change the main config on the master node (MIaB) and I’m unsure if this may break the admin portal or gets overwritten by next config change. Can someone comment on this?
Would others support a request for the improvement?
