Replaces three handfuls of custom code with upstream / static data:
- Per-app Steam launch options now declared via different-name/steam-
config-nix's `programs.steam.config.apps.<n>` instead of a custom
~70-line `apply_launch_options` Python function. The dropped writer
was racy: it edited localconfig.vdf without checking for a running
Steam, so any timer firing while Steam was open would lose its
changes on the next Steam shutdown. steam-config-nix's `closeSteam`
flag closes that race.
Also moves the GE-Proton compat-tool pin to declarative config —
one fewer manual click in Steam UI to remember.
- `mods.<>.launchOptions` option, the `launchOptionsData` aggregation,
and `LAUNCH_OPTIONS_DATA` are removed from desktop-game-mods.nix.
The module now does file-drops only; Steam config lives in its own
`programs.steam.config` namespace, where it belongs.
fh5-vkd3d-no-hvv (which existed only to set VKD3D_CONFIG) collapses
into the FH5 launchOptions block in hosts/yarn/default.nix.
- `unitConfig.X-ConfigHash` on game-mods.service is replaced with
`restartTriggers`. NixOS already emits `X-Restart-Triggers=<hash>`
on the unit; the workaround was redundant. The Type=oneshot,
RemainAfterExit=no semantics make `systemctl restart` re-run
ExecStart cleanly on hash change.
- The awk pipeline that patched OptiScaler's stock OptiScaler.ini at
build time is replaced with a hand-written hosts/yarn/optiscaler-
fh5-rdna3.ini containing only the keys we override (5 of them).
OptiScaler's Config::readString defaults missing keys to "auto"
(Config.cpp:1568), so a minimal file is sufficient. Side benefits:
one upstream-source dependency removed, a key-rename in upstream
becomes a behavior change rather than a silent awk-no-match.

- forza-trigger's three custom Python derivations (pydualsense,
hidapi-usb, fdp) factored out of default.nix into a sibling
python-packages.nix. Same logic, single-purpose file. Bumping a
version is now a one-place hash roll.
- pkgs.dualsensectl removed from the daemon's environment.system-
Packages. Single-shot writes from the CLI get clobbered by the BG
sendReport thread within ~4ms anyway, so the tool is only useful
with the daemon stopped — not worth the unconditional install.
Bring it in ad-hoc with `nix-shell -p dualsensectl`.
stdenvNoCC + p7zip extraction; strips installer scripts and README,
keeps Licenses/. dontFixup since the artifacts are Windows DLLs.
meta.license is unfreeRedistributable to reflect the bundled XeSS
(Intel SLA) alongside the GPL-3.0 source.
Wires lib/overlays.nix into mkDesktopHost (was muffin-only) and adds
"optiscaler" to the unfree allowlist on jovian hosts so yarn can
consume it without flipping the global allowUnfree flag.
new site-config.nix holds values previously duplicated across hosts:
domain, old_domain, contact_email, timezone, binary_cache (url + pubkey),
dns_servers, lan (cidr + gateway), hosts.{muffin,yarn} (ip/alias/ssh_host_key),
ssh_keys.{laptop,desktop,ci_deploy}.
threaded through specialArgs on all three hosts + home-manager extraSpecialArgs +
homeConfigurations.primary + serverLib. service-configs.nix now takes
{ site_config } as a function arg and drops its https namespace; per-service
domains (gitea/matrix/ntfy/mollysocket/livekit/firefox-sync/grafana) are
derived from site_config.domain. ~15 service files and 6 vm tests migrated.
breakage fixes rolled in:
- home/progs/zen/dark-reader.nix: 5 stale *.gardling.com entries in
disabledFor rewritten to *.sigkill.computer (caddy 301s the old names so
these never fired and the new sigkill urls were getting dark-reader applied)
- modules/desktop-common.nix: drop unused hugepagesz=1G/hugepages=3
kernelParams (no consumer on mreow or yarn; xmrig on muffin still reserves
its own via services/monero/xmrig.nix)
verification: muffin toplevel is bit-identical to pre-refactor baseline.
mreow/yarn toplevels differ only in boot.json kernelParams + darkreader
storage.js (nix-diff verified). deployGuardTest and fail2banVaultwardenTest
(latter exercises site_config.domain via bitwarden.nix) pass.
Reset u->freezer_state to FREEZER_RUNNING when a unit transitions to
inactive/failed. Without this, any SIGKILL path to a frozen unit
(systemctl kill, OOM, watchdog SIGABRT-then-KILL, segfault) leaves
the unit stranded at FreezerState=frozen with no recovery short of
a reboot. Complements upstream PR #38528 which covers only the
watchdog path.
xmrig-auto-pause never calls `systemctl freeze` itself (direct
cgroup.freeze writes bypass the bug class entirely), so the patch
is defensive: benefits systemd-homed on lock, user-session freezing
on suspend, or anything else that may freeze units on muffin.
Patching systemd cascades udev-check-hook hash changes into fuse3 -->
e2fsprogs and into fish. Two test-suite workarounds ride along:
drop e2fsprogs m_hugefile (4 GiB sparse file, fails on some build
sandboxes) and fish doCheck=false (cargo pexpect TTY tests). Both
are environmental, unrelated to the patch.
