What maps to what

pm tree (removed)	NixOS	Notes
recipes/10-systemd/linux, losos.config	nixpkgs' kernel, hardware.nix	nixpkgs' common-config.nix already sets what systemd needs, CONFIG_HIDRAW included. zswap is built in and off, and boot.zswap.enable turns it on
recipes/10-systemd/nvidia-open	nvidia.nix: nixpkgs' NVIDIA open module and userspace	chosen per machine at boot from nixos-facter's report; older cards keep nouveau and NVK (Hardware and NVIDIA)
recipes/00-* through 30-gnome, manifest/, share/	nixpkgs	every package the recipes built. Their build-system patches existed only for the CFI toolchain
recipes/30-gnome/gnome-control-center patches	nixos/pkgs/patches/gnome-control-center/	kept and not applied, see What is not done
recipes/90-image/losos-image (mkosi), plugins/	nixos/modules/image.nix (image/repart.nix)	the same systemd-repart; no fingerprint table to get past, so no plugins
mkuki.py, files/cmdline	boot.uki, verity-store module	the UKI carries usrhash=
overlay/usr/lib/repart.d/	systemd.repart.partitions in disk.nix	runs in the initrd, as before
overlay/usr/lib/sysupdate.d/	systemd.sysupdate.transfers in update.nix	UKI plus both /usr halves
overlay/usr/lib/repart.sysinstall.d/, systemd-sysinstall	installer.nix, nixos/installer/	see The installer
overlay/usr/lib/systemd/system-preset/10-losos.preset	the module options themselves	on NixOS a unit is enabled by being wanted, not by a preset
overlay/usr/lib/sysusers.d/losos.conf	systemd.sysusers.enable over users.users	the upstream tool, not NixOS's perl script
overlay/usr/lib/tmpfiles.d/losos.conf	systemd.tmpfiles.settings in services.nix
overlay/usr/lib/systemd/network/20-wired.network	systemd.network.networks."20-wired"	same match and settings
overlay/etc/crypttab, overlay/etc/fstab	environment.etc.crypttab, swapDevices
user@.service.d/10-oomd.conf	systemd.oomd, systemd.slices.user
losos-security.service, its D-Bus files	services.nix	same sandbox, line for line
50-losos-factory-reset.rules	security.polkit.extraConfig in disk.nix	same rule
losos-selftest.service, losos-ota-test.service	nothing	no test booted with either; the selftest made an ordering cycle that could drop boot-complete.target, see nixos/modules/default.nix
recipes/10-core/losos-release	system.nixos.distroId, system.image.*	NixOS writes os-release itself, with IMAGE_VERSION
manifest/architectures.yaml	losos.arch in options.nix	x86_64 and aarch64
tools/configure --version --channel	losos.version, losos.channel	the flake derives the version from the commit date
tools/vm-test	nixos/tests/boot.nix	boots the real image under UEFI
tools/ gates, Containerfile, ./do	nix flake check, nix fmt	the gates checked generated recipes against pm's fingerprint table, and neither exists now
pm, the system manager	pm, the system manager (pm.nix)	the components/pm submodule
