* security: make firewall secure-by-default, disable explicitly on servers
Flip the base firewall default to ON so new hosts are protected by default. Servers keep the firewall off (trusted internal LAN, WAN protected at the router) via explicit overrides in modules/nixos/server/{server,server-aarch64}.nix. Behavior-preserving for all 18 current hosts; adds a security-firewall eval test guarding the per-host state.
* test: fix security-firewall eval test to scalar per-host values
* security: enable AppArmor (complain) on all Linux hosts
* security: bind aquamarine metrics exporters to loopback
* security: restrict k3s kubeconfig file mode to 600
* security: disable SSH X11 forwarding on servers, keep on desktops
* security: add conservative systemd hardening to aquamarine services
* docs(apparmor): correct FHS-alias comment (nixpkgs has no broad FHS layer)
nixpkgs only creates /run/current-system, /usr/bin/env and /bin/sh; it does not
provide a broad FHS->store alias tree, so FHS-oriented abstractions are incomplete
on NixOS. They are safe only because the profiles run in complain mode.
* fix(aquamarine): scrape same-host exporters over loopback
The v2ray/postgres/sftpgo exporters were bound to 127.0.0.1 but VictoriaMetrics
scraped them via the host's routable IP, so those scrapes refused connections.
Point the three same-host scrape targets at 127.0.0.1 (VM runs on the same host).
node-exporter keeps the host IP since it binds 0.0.0.0.
* Revert "security: add conservative systemd hardening to aquamarine services"
This reverts commit f9cf99dadb.
At login the xdg-autostart-generator starts apps at
graphical-session.target, racing the portal user services. Sandboxed
apps (nixpak firefox/telegram) end up with broken FileChooser/OpenURI
until manually restarted.
Add a template drop-in on app-@autostart.service that makes every
autostart app wait for the portal stack.
Nixpkgs removed services.kmscon.fonts and services.kmscon.extraConfig, so the old font module failed evaluation on current nixos-unstable.
Move the selected font, font size, and hardware acceleration settings into services.kmscon.config while keeping the existing terminal type option.
* feat: comment out nixpkgs-unstable, we use unstable by default
