[dnsmasqyq.xpt at neverbox.com]

Hi, I'm installing in Debian the normal way with

sudo apt install -y dnsmasq

and it fails out of the box with:

------------------------------
Created symlink /etc/systemd/system/multi-user.target.wants/dnsmasq.service
-> /lib/systemd/system/dnsmasq.service.
Job for dnsmasq.service failed because the control process exited with
error code.
See "systemctl status dnsmasq.service" and "journalctl -xeu
dnsmasq.service" for details.
invoke-rc.d: initscript dnsmasq, action "start" failed.

Is it that my network device is not eth0 but br0 instead?
