NetworkManager documentation does not document proper way to use different tools for dns /dhcp management

[nivlac]

The only mention of dnsmasq in the manpage only refers to resolver.conf. This is misleading
since dns=none would appear to stop NetworkManager from running dnsmasq, yet it does not. So
until the non-existent "disable dnsmasq" checkbox/radio button appears in the NetworkManager gui interface (edit connections) the documentation MUST include narrative on proper way to use NetworkManager with dhcpd, bind9 and friends. The amount of confusion and wasted time caused by this can easily be seen on google. After three days of work I am still uncertain that its even possible.

This applies to 16.04 specificly but has been an issue since NetworkManager started using dnsmasq.

From the manpage:

man NetworkManager.conf

       dns
           Set the DNS (resolv.conf) processing mode.

           default: The default if the key is not specified. NetworkManager will update resolv.conf to reflect the nameservers provided by currently active connections.

           dnsmasq: NetworkManager will run dnsmasq as a local caching nameserver, using a "split DNS" configuration if you are connected to a VPN, and then update resolv.conf to point to the
           local nameserver.

           unbound: NetworkManager will talk to unbound and dnssec-triggerd, providing a "split DNS" configuration with DNSSEC support. The /etc/resolv.conf will be managed by dnssec-trigger
           daemon.

           none: NetworkManager will not modify resolv.conf.
