I have no idea when I have previously looked into those two files (git
history would probably tell me), but I don't think they make much sense,
while the important parts can be cut into conf.d/ and applied
individually as needed.
Strangely Itwjyg is a special case system where I need systemd-resolved
and its opportunistic DNSSEC/DoT. I also accidentally forgot
dns-none.conf (then dns.conf) there, but systemd-resolved.conf appears
to have overridden it, so it was fine and I have now removed the extra
one.
I want DNSMasq to behave a little differently from the NetworkManager
defaults.
The default cache size of 150/400 seems a little small and 10 000 probably
won't be full soon and I am sure modern systems at least at home where I
am using dnsmasq again won't suffer from it.
By default dnsmasq started by NEtworkManager only listens on 127.0.0.1
while ::1 also exists, I want it to be also listened on in case anything
decides to try querying with it.
DNSSEC is not checked by default while I want that behaviour, but as I
am using OpenDNS I cannot make it verify unsigned zones are unsigned :(
Also add symlink to trust-anchors.conf that should ship with DNSSEC to
avoid having to deal with it manually. It should work as a reminder that
it's also needed.
