OSMC ships with DNS proxying disabled. We have noticed that some users report DNS priorities to not work as expected. It seems that nameservers are written in reverse order in /etc/resolv.conf. I checked resolver.c:
* Domains and nameservers are added in reverse so that the most
* recently appended entry is the primary one. No more than
* MAXDNSRCH/MAXNS entries are used.
I think this is non standard behaviour -- DNS servers should be written in the same order received from DHCP. If this is not the case, then DNS ordering should at least be identical regardless of whether DNS is being proxied or not.
