Iniciando o servidor DNS dnsmasq do Ubuntu com opções personalizadas

Question

Como iniciar o servidor DNS dnsmasq do Ubuntu com opções personalizadas? Eu simplesmente comecei como:

dnsmasq --log-async --log-queries

No entanto, não consigo mais acessar o Google Drive:

This site can’t be reached
drive.google.com’s server DNS address could not be found.

$ dig drive.google.com

; <<>> DiG 9.10.3-P4-Ubuntu <<>> drive.google.com
;; global options: +cmd
;; Got answer:

Eu acho que existem algumas opções de dnsmasq padrão do Ubuntu também, certo? Então como? THX.

Encontrado o caminho correto,

$ printf 'log-queries\nlog-async\nmax-cache-ttl=10800\n' | sudo tee /etc/dnsmasq.d/dnsmasq.cache.conf
log-queries
log-async
max-cache-ttl=10800

$ sudo /etc/init.d/dnsmasq restart
[ ok ] Restarting dnsmasq (via systemctl): dnsmasq.service.
