Após a inicialização, eu tenho que reiniciar o NetworkManager do Ubuntu 16.04 para que ele funcione. Eu me pergunto por que e como posso evitá-lo.
Eu fiz as seguintes alterações:
Na GUI, para a conexão Ethernet com fio que estou usando, na guia IPv4 Settings , selecionei como Método Automatic (DHCP) addresses only e não tenho entrada em DNS servers .
Eu adicionei um arquivo em /etc/NetworkManager/dnsmasq.d/unbound.conf com o conteúdo:
server=127.0.0.1#5553
enquanto estou executando um servidor DNS alternativo nessa porta, que está funcionando bem.
Analog to unbound.conf descrito acima, tenho mais dois arquivos conf para usar servidores DNS alternativos para .lxc e .lxd domains, por exemplo, para .lxd :
server=/lxd/10.0.8.1
Este é o log gerado ao inicializar:

Como solução, o NetworkManager pode ser reiniciado após a inicialização adicionando automaticamente essa linha a /etc/rc.local (antes da linha exit 0 ):
systemctl restart NetworkManager.service
