Personal note on the state of Gluetun

I have been focusing my effort since mid November on a DNSSEC validator to finalize a Go library on par with the usage we have of Unbound, in order to replace Unbound in Gluetun and add DNS special features for Gluetun. For example:

• automatically diverting local hostnames questions to the local Docker DNS server (a long overdued problem) - already implemented
• allow resolution of VPN endpoint hostname to ips in a very restricted DNS server + firewall to only allow a specific hostname to resolve (not implemented yet)

This is a tough problem not so well documented with few complete and valid implementations, so it's taking some time. There is likely 2 more weeks of work left before finalization.
