* 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.
