Just a quick post to catalogue some of the errata they haven’t posted about yet.
The DNS (configuration) is a lie
The DNS settings in LuCI are almost completely non-functional – with no indication, because the Omnia is using some combination of Unbound and Knot for DNSSEC. This means I’m currently getting less features out of the resolver on my router than I was running dnsmasq on FreeBSD.
Some solutions are listed at https://forum.turris.cz/t/how-to-configure-local-address-dns-resoultion-on-omnia/, but many would involve me having to re-configure IPv6, which is a pain.
