NixOS copies mode-carrying /etc entries such as authorized_keys.d during
stage-2 activation, which runs before systemd starts. preservation mounted the
persisted /etc/ssh from preservation.target afterwards and hid that copy, so a
key change only took effect on `switch`: revoking a key and rebooting silently
restored the old one.
Prepare the mount in initrd, before activation runs, and cover it with a VM
test that seeds a stale authorized_keys file, reboots, and asserts the declared
key replaced it. The same test fails on that assertion with inInitrd disabled.
Verified on all four hosts: /persistent/etc/ssh/authorized_keys.d/root is now
rewritten at boot instead of keeping the timestamp of the last switch.

* chore(nix): update nixpkgs to e62746b and fix 26.11 breakage
Bump nixpkgs to e62746b and preservation to 00be7f7, then adapt to the removals and renamed options in the new revision: drop the removed boot.initrd.systemd.enable settings, trim the stale emSign CA blacklist on Linux while keeping it for the older Darwin input, and migrate Avahi publishing to settings.publish. Work around sunshine still setting the legacy Avahi options and keep dsh-nu on its tested Nushell 0.115.1. Patch NUR dsh's pnpm call to pass nodejs = null, and update pyclipsync for the stdenv.hostPlatform.system rename.
* chore(nix): refresh flake inputs for 26.11
- update nixpkgs-darwin to the same e62746b revision as nixpkgs
- make dsh-nu follow main nixpkgs and patch its testedWith manifest for the resolved Nushell
- refresh floating inputs; update lanzaboote, tuios, and ponytail
- drop the nixpkgs-2505 and rust-overlay workarounds
- keep pyclipsync on main and simplify the cross-platform CA blacklist
- adopt home-manager's Nushell loadSessionVariables default
* fix(gitea): use ROOT_URL for nixpkgs 26.11
nixpkgs removed the legacy settings.server.DOMAIN option; the existing ROOT_URL already carries the public URL.
* chore(nix): update dsh-nu to 0.7.0

Add Immich via the native nixpkgs services.immich module on youko, reusing the host PostgreSQL 16 (pgvector + vectorchord) and a shared Valkey instance for Redis-compatible caching and BullMQ queues (Dragonfly rejected BullMQ's dynamic Lua keys). Media lives on the encrypted HDD at /data/apps/immich; Caddy publishes immich.writefor.fun with a publicly-trusted Let's Encrypt cert (security.acme + Cloudflare DNS-01) so the mobile app connects. OTEL metrics are scraped by VictoriaMetrics, and /var/cache is now preserved on the tmpfs-root hosts so the ML model cache survives reboots.
Drop the now-meaningless kubevirt- prefix and move the hosts out of
hosts/k8s/, following the existing 12kingdoms-shoukei layout: the
directory and output carry the theme prefix while the configuration,
hostname and colmena target are the bare name (shoryu, shushou, youko).
- hosts/k8s/kubevirt-* -> hosts/12kingdoms-*; the shared disko config
becomes host-disko-fs.nix; the now-different relative imports are fixed
- outputs, vars/networking.nix keys, the Justfile recipes/tags, the eval
tests and the docs follow
- colmena reaches these hosts by IP (a new targetHost override), since
their DNS name changes with the hostname and is not resolvable until
the router learns it
