The file is not KubeVirt-specific: it is the hardware configuration for
any QEMU guest that boots from a disk (KubeVirt or libvirt). All it does
is pull in qemu-guest.nix and set fileSystems."/" from the disk labeled
nixos.
English stays the default (LANG=en_US.UTF-8). Drop the Chinese overrides for
LC_TIME, LC_NUMERIC, LC_ADDRESS, LC_NAME, LC_TELEPHONE and LC_IDENTIFICATION:
LC_NUMERIC matches en_US, the others are effectively unused, and LC_TIME forced
Chinese date and weekday names.
Keep zh_CN only where the en_US default is wrong for China: metric units, A4
paper and CNY.
Noctalia v5 is the native C++/Wayland rewrite; the Quickshell-based v4 line (pkgs.noctalia-shell) is EOL and its JSON config is not migrated upstream.
- use the upstream home-manager programs.noctalia module (present at our pinned HM revision) instead of the hand-rolled package + symlink module: it installs pkgs.noctalia, validates config.toml at build time via checkConfig, and supports customPalettes; drop the v4 Qt/Qt6ct session setup
- replace the v4 settings.json/plugins.json with a minimal shared config.toml (font, Catppuccin shell palette, templates off, screenshot annotation, accessibility/bar scale, night light, wallpaper, location/weather); host-specific bits live in per-host files (shoukei's eDP-1 backlight in noctalia/host-shoukei.toml), which merge after config.toml. Application theming stays with catppuccin/nix
- treat config.toml as the single source of truth: do NOT persist ~/.local/state/noctalia and set setup_wizard_enabled = false, so UI tweaks are promoted back into the repo instead of accumulating in app-owned state
- port niri keybinds to 'noctalia msg ...', update spawn-at-startup and the backdrop layer namespace, fix the broken 'octalia-shell' media-previous bind, and replace the grim/slurp/satty screenshot stack with Noctalia's native region/fullscreen/annotate commands (drop the unused packages)
- drop the now-redundant swaybg and swaylock (Noctalia owns the wallpaper and lock screen, the latter authenticating against the PAM 'login' service) and its PAM entry; keep wlogout as an emergency fallback
- update hypridle's lock commands and the matching eval test
- refresh the noctalia docs
networkd enables systemd-resolved by default, and resolved's own mDNS responder conflicts with avahi (duplicate answers, avahi logs 'Detected another mDNS stack running on this host'). Keep avahi for DNS-SD (cups-browsed depends on it) and turn resolved's mDNS off.
trash-empty lacked Persistent=true, so a host that was off or suspended at the scheduled time never ran the purge and trash retention silently stopped.
Guix was enabled on every desktop host, but shoukei had no /gnu mount (store and state lived on the tmpfs root) and it was not used. Drop the module, the modules.guix option, the @guix subvolume and the /var/guix preservation entry.
* feat(btrbk): make snapshots explicit and guarded
Replace the always-on, hardcoded module with modules.btrbk options (enable/volume/subvolume/snapshotDir/target/onCalendar), and assert the btrfs top-level subvolume is mounted so a missing mount fails evaluation instead of silently failing at runtime.
Store snapshots in the @snapshots subvolume (snapshot_dir=@snapshots) rather than next to the live subvolume, make the off-host target explicit and off by default, and document that local snapshots are not off-host backups.
Enable the feature explicitly on idols-ai, shoukei and the three kubevirt hosts; qemu-guest now disables it through the option. Add eval tests for shoukei and ai.
* feat(monitoring): alert on btrbk snapshot failure
Add HostBtrbkSnapshotFailed on node_systemd_unit_state for btrbk-btrbk.service, so a broken snapshot schedule alerts instead of only surfacing in the journal.
Install microsoft-edge on x86_64 Linux via Home Manager and on macOS via
a brew cask. Enable the chromium and brave-origin Home Manager options
alongside google-chrome, dropping the google-chrome aarch64 fallback to
chromium since google-chrome supports aarch64-linux.
Persist the Brave Origin and microsoft-edge profile directories on the
ephemeral-root hosts.
- render Niri on the Intel iGPU while retaining NVIDIA-connected physical outputs
- encode Sunshine streams with Intel VAAPI and wait for a Niri output before startup
- load VKMS persistently for headless sessions and configure `Virtual-1` at 2560x1600@60
- let Moonlight request the stream bitrate instead of enforcing a 20 Mbps host cap
- remove unsupported Dynamic Boost and global NVIDIA session overrides
- grant Sunshine access to virtual input devices
- add a Nushell recovery helper that starts a temporary greetd/Niri session from SSH
- identify and safely replace normal, standalone, or previous transient Niri sessions
- launch the transient service in the background and verify greetd, Niri, and Sunshine before returning
- ignore local `.worktrees` directories and keep eval regression coverage focused on structural behavior
Enable gnomeKeyring for the passwd PAM service so pam_gnome_keyring
updates the login keyring password when the login password changes.
Fixes 'Unlock Login Keyring' prompt desync after changing the password
via passwd (greetd session unlock alone does not update the keyring).
The zram module was auto-imported on all hosts via base scanPaths, and its
swappiness=180/page-cluster=0 tunings leaked onto hosts that disabled zram
(e.g. idols-ai with a disk swapfile, pushing cold anon pages to disk swap).
Wrap the whole module in modules.zram.enable (default true); idols-ai now
turns off zram and its tunings with a single switch.
* 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.
* feat(nushell): add trash command using the home trash can
On a tmpfs root with persistent dirs bind-mounted in, `rm --trash`
scatters items into per-mount .Trash-$uid dirs that file managers never
show, and gio refuses to trash on those internal mounts.
Add a `trash` command implementing the freedesktop trash spec
'failsafe' mode: items are moved to ~/.local/share/Trash with
spec-compliant .trashinfo entries, so Thunar can list and restore them.
Also preserve ~/.local/share/Trash on idols-ai so the trash survives
reboots.
* feat(nixos): manage scattered trash dirs with trash-cli retention timer
Replace the hand-written nushell trash command with the established
trash-cli tooling. On a tmpfs root with persistent dirs bind-mounted
in, the trash crate (nushell rm --trash) scatters items into per-mount
.Trash-$uid dirs that file managers never show and nothing cleans up.
- add trash-cli to system packages: trash-list scans/trash-restore
handles every mount point's trash dir
- daily systemd timer runs 'trash-empty 30 -f', purging items older
than 30 days across the home trash and all mount points
- drop the hand-written trash.nu module
- note in preservation.nix: do NOT persist ~/.local/share/Trash; a
bind-mounted trash dir breaks the trash crate's home-topdir match
for files straight under $HOME (it would try /.Trash-$uid, EACCES)
* fix(nixos): order trash-empty after preservation.target
The scattered .Trash-$uid dirs live inside the preservation bind
mounts, which use DefaultDependencies=no and are therefore NOT ordered
after local-fs.target. Add preservation.target to After= so trash-empty
only runs once all those mounts are up.
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.
Setting nix.settings.sandbox-paths replaces Nix compiled sandbox defaults. Keeping only /dev/net made local builds lose the sandbox shell that normally provides /bin/sh, which broke upstream scripts with /bin/sh shebangs in packages such as X11-fonts and openldap.
Use extra-sandbox-paths for /dev/net instead. This keeps Nix daemon defaults intact, including the configured sandbox shell, while still allowing builds that need /dev/net.
Add eval coverage for both Linux output sets so future changes keep /dev/net in extra-sandbox-paths and do not reintroduce an explicit sandbox-paths override.
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.
* chore(home): drop AstroNvim bundle and centralize editors
Remove the bundled Neovim plugin tree to shrink supply-chain exposure; keep a
minimal programs.neovim backup. Daily editing stays Helix-first with Yazi and
Zellij.
- Add Helix/Neovim docs, glossary, and cheatsheets under core/editors/.
- Default EDITOR/VISUAL to hx; use SUDO_EDITOR nvim --clean for sudoedit and
other sensitive edits; adjust Nushell buffer_editor accordingly.
- Apply Helix Home Manager settings (keys, editor UI) in core/editors/helix.
- Keep heavy language-server tooling only in home/base/tui/editors/packages.nix;
wire it via an explicit default.nix import so core stays lightweight.
- Extend modules/base packages.nix where that profile sets global editor env.
* docs: link editors, VS Code, and agents from README
Document tui/editors versus core/editors; add root README pointers to GUI
vscode (Home Manager) and agents/. Cross-link heavy packages README from
core/editors.
