DNS over TLS configurations broken in Turris OS 3.11
To reproduce, set up a DNS over TLS configuration on Turris OS 3.11 as documented at this link. Then reboot the router. All DNS name resolution via kresd will be broken. This worked in 3.10.8. Oddly, if you then restart kresd using
/etc/init.d/resolver restart
then DNS over TLS works. Not sure if this is some timing or dependency issue.
