Previously, it was hosted on Ionos’s VMware-based infrastructure. I
already had a VPS on their new KVM-based infrastructure, as I was
planning to migrate okarin to it eventually (as it is cheaper). However,
the new infrastructure does not offer PTR records for IPv6 addresses.
Therefore, I was waiting until they would implement that feature (as the
support promised me they would to in the near future).
However, they are now migrating the (at least my) guests from their
VMware hypervisors onto the KVM ones, assigning new IPv6 addresses to
them. This makes the old VPS essentially the same as the old one, but
with less memory and more expensive. So I decided to migrate now.
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.
This is needed for Intel Arc support (Mesa 22.3+).
This also makes changes so the nixpkgs system evaluates without
errors/warnings (caused by my configuration).
