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.
It fails on laptops thanks to not being able to do DNS resolution thanks
to network connection not existing during boot.
Now it fails to `Download snap "ubuntu-core" (423) from channel "stable"
(cannot authenticate to snap store: Provided email/password is not
correct.)` which is process and appears to not be my issue.
Only oidentd.socket and miredo.service were copied instead of being
units that exist in the system and they don't need to do anything
else than fix the issue I have with the stock units.
* oidentd.socket is IPv6-only on my systems unless is BindIPv6Only=both.
because of net.ipv6.bindv6only=1
* miredo.service is here because it starts before there is network
connection (network-online.target) and there is never network
connection with laptops before they are connected to WLAN even if
NetworkManager might be up seeking/connecting to network.
