From 312dd2b8969ed0a655737a291cac796aac0fb7d4 Mon Sep 17 00:00:00 2001 From: parzivale Date: Tue, 25 Aug 2026 15:55:36 +0200 Subject: [PATCH 1/7] tests: init the finix compatibility suite modules here are minimally maintained by design and finix moves fast, so the question worth answering per module is "what finix commit did this last work with". nothing in the repository could answer it: `nix flake check` had no checks to run. tests live next to the module they cover, one file per test, and each is checked at up to two depths. `eval` imports the module into an otherwise minimal finix system, enables it and instantiates the closure - cheap, and it catches the option and api drift that actually breaks these modules. `vm` boots that same system and asserts the module does its job, using finix's own test driver so a test file here looks like a test file there. every module is covered. the ones that need a gpu, a seat or real hardware are eval-only and carry a note saying why, which the table quotes. a module with no tests/ directory fails `-A registration`, so nothing can quietly drop off. packages come from the nixpkgs finix pins rather than ours, so a result depends on the finix commit alone.

[PATCH 3/7] modules/dinit: boot the user service manager in a vm dinit's job on a finix host is the per-user session - finit is pid 1 - and the module writes `dinit.user.services` to /etc/dinit.d/user, which is one of the directories `dinit --user` searches. that is testable, so test it: boot a host, start dinit as an unprivileged user, and check it runs a scripted service, supervises a process service as that user, applies the env-file the module generated, and restarts the process when it is killed. the system half stays eval-only and says why in its own file: those land in /etc/dinit.d for a dinit running as system service manager, and nothing on a finix host picks them up. notes are now attributed per test rather than per module, since dinit has one of each; the table gained a "what is not booted, and why" section that names the test instead of implying the whole module is eval-only. also copy the generated table with `install -m 644` - copying a store path's mode along left it read-only, and the second run could not overwrite it.

amnezia-vpn and v2rayn are gui clients, but the module ships a daemon in one case and a wrapper that links the xray/sing-box cores into the user's data directory in the other, and both run headless - dinit's system half is supervised under `dinit --container`, which is a system service manager that does not try to be pid 1 - gamescope and river both have headless backends; river's test also covers the rebuild against libudev-zero that picking mdevd forces - openrgb's sdk server does not need a controller to accept clients - pipewire runs with an empty graph when there is no sound card - preservation is checked where it actually acts: the initrd, with a volume mounted for boot and the declared paths bind-mounted onto it by the time the machine is up - soteria gets as far as a headless machine can: polkit up, the service loaded, and the agent started at the graphical runlevel it asks for - steam stops at its fhs environment and the 32-bit driver path, which is the expensive-but-bounded part - the laptop profile is booted and checked for the seat, device, network, power and firewall services it picks console waits are bounded now. without a timeout a machine that fails to boot holds the driver until its hour-long global timeout, which is a bad way to spend a ci run.

the test says what the module actually gets from dbus - nix-ld's loader name now follows the platform instead of hardcoding x86_64 home-manager cannot run activation in the test vm: it sets the generation profile with nix-env and /nix is a read-only 9p mount. the test checks the service the module wires in, the generation it points at, and the managed file built into it, and says so in the file.

drop both, the init script only needs to prove it ran. soteria: two real bugs surfaced by actually booting it (previously eval-only). The module's compiled-in polkit-agent-helper-1 path comes from whatever polkit soteria happened to be built against, which is not the (overridden) one `services.polkit` deploys here - point it at the real wrapper via /etc/soteria/config.toml. And soteria reads XDG_SESSION_ID from its own environment, so it can't run as a system finit service with no login session; it's now installed only, meant to be started from wherever a session already starts other session programs (documented in the option), and the vm test proves this end to end via a real autologin + elogind session with a headless river compositor giving its gtk4 UI a display to attach to. xinetd/steam test tweaks from local debugging carried along as-is.
