A bug in dnsmasq 2.86-10 would render the whole DHCP system down. Once you modify the /etc/dnsmasq.conf with additional line:

conf-dir=/etc/dnsmasq.d/

Your dnsmasq will refuse to start

Workaround: Add following lines to /etc/config/dhcp to bypass this bug:
option confdir '/etc/dnsmasq.d/'

This workaround will change the default behavior which dnsmasq was including the conf files in the /tmp/dnsmasq.d
And I'm not sure if the option confdir '/etc/dnsmasq.d/' actually works.


The dnsmasq 2.85-8 package shipped with 21.02.1 has no such bug.
