journalctl -xe errors: dnsmasq: failed to create listening socket for 127.0.0.1: Address already in use.

see https://serverfault.com/questions/617205/dnsmasq-failed-to-create-listening-socket-address-already-in-use

Questions:

• what port is it using? -- /nix/store/y30wq9zxc2r7xmkj0qnj1cvcmxfpw9p6-dnsmasq-2.79/bin/dnsmasq --help | grep port: defaults to 53
• what else is using this port?

  $ sudo netstat -nlp | grep dnsmasq
  tcp        0      0 0.0.0.0:53              0.0.0.0:*               LISTEN      1354/dnsmasq
  tcp6       0      0 :::53                   :::*                    LISTEN      1354/dnsmasq
  udp        0      0 0.0.0.0:53              0.0.0.0:*                           1354/dnsmasq
  udp6       0      0 :::53                   :::*                                1354/dnsmasq

• ~how to make it use a different one?~
• ~does anything else need to know it's on a different port?~

So... it's already running?

Disabled this -- seems to still be running, without spamming the log with errors...
