Connect home network with IPv6 addresses 
It adds a bit of latency (and is definitely not the best solution in
theory), but finally allows dropping IPv6 NAT and it works within the
constraits my home network has to live in.

shinobu: Add NTP server 
This also changes the firewall rules for the IoT network to no longer
accept connections to ntp.org pool hosts over 123/UDP. All clients
should use the local NTP server.

Relicense 
This applies the REUSE specification to the repository, so the licensing
information can be tracked for every file individually.

Switch home domain to shinonome-lab.de 
When having DNSSEC activated (as it is the case on sbruder.de), dnsmasq
interfering in queries for hosts on the LAN often causes problems.

This domain is specifically for the case of not having DNSSEC on it.

shinobu/router: Disable hostapd 
The wireless card only supports one AP, so I switched to an OpenWRT
stanadlone AP.

restic: Use QoS instead of uploadLimit 
This implements a crude mechanism for signalling my router to add the
packets to its own qdisc.

The way in which this is implemented with nftables is hacky because of
NixOS’ limitations on build-time checking (which obviously can’t know
about the existence of cgroups on the target).

shinobu/router: Implement QoS using HTB 
This is an initial implementation and probably still needs tuning.

shinobu/router: Disable wg-upstream 
This only complicates many things and creates too much overhead on such

Some of my learnings are documented as comments in the rules.

Revert "shinobu/router: Switch provider for wg-upstream" 
This reverts commit 0bcc5d6141.

This leaves MSS clamping in place.

shinobu/router: Fix IPv6 networking 
Previously, I did not have IPv6 upstream, so even a wrong configuration
worked. Now it uses a different routing table for IPv4 and IPv6, so it
also works on dual-stack upstreams.

However, how it worked without IPv6 forwarding enabled, is still a
mystery to me.

shinobu/router: Switch provider for wg-upstream 
The old provider was doing weird stuff with DNS that I wasn’t able to
debug well.

However, apparently, the old provider did MSS clamping on their side.
Therefore, it is now required that I do this on my side.
