 ## Transition
 
-- **From omacom/omarchy-mac-pkgs (20261004-1).** The package no longer carries the migration engine: `omarchy-mac-migrate`, `/usr/lib/omarchy/mac-boot/migrate`, the `migrate-*.sh` modules and `omarchy-mac-migrate-verify.service`. pacman removes them on upgrade, and the scriptlet drops the verify unit's enable link the engine left. Converting a fork or mx-mac Mac is a separate migration script. A Mac stopped between a migration's reboot and its verification (`/var/lib/omarchy-mac/migration/reboot-pending`) must finish it before this upgrade: afterwards nothing verifies that boot.

 - It provides, conflicts with and replaces `omarchy-apple-boot` and `omarchy-first-boot`. The scriptlet moves a pending `omarchy-first-boot` marker to `omarchy-mac-first-boot`, drops the dangling enable links of the replaced unit and of the removed migration verifier, and points at a customised `90-omarchy-asahi.conf.pacsave`.
 - `pkgver` is the UTC commit date of the pin, so any pin from `20260925` on upgrades the fork's `20260921-10` on mx-mac Macs. The files the fork shipped that the source no longer does (the image finalize tools, the upstream ARM repository key and the GRUB snapshot-menu hook) are removed by that upgrade.
+- **Device tree overlays (omacom/omarchy-mac-pkgs#3).** Other packages may drop overlays into `/usr/lib/omarchy-mac-boot/dtb-overlays/`, which this package owns; `/etc/default/update-m1n1` applies them and the boot check rebuilds `boot.bin` the same way. With none installed, `boot.bin` is unchanged. A Mac with its own copy of `/etc/default/update-m1n1` keeps it (the shipped one lands as `.pacnew`), and then update-m1n1 applies no overlays until it is merged. The overlay hook does not run in the transaction that first installs it.
 - `backup=` covers every `/etc` file and `/usr/lib/omarchy/initcpio`. It includes `/etc/default/update-m1n1`, which pins update-m1n1's device-tree order to the C locale. On a Mac that already has its own unowned copy, pacman keeps it and installs the shipped one as `.pacnew`. The snapshot restore hooks in `/etc/boot/hooks` are symlinks to `/usr/bin/omarchy-mac-snapshot-check`, not files, so they stay out of it.

 `depends` carries what every Mac needs, so an offline first boot has it and an owner can't remove it: the speaker stack with `speakersafetyd` named (its unit is this package's preset), `alsa-ucm-conf-asahi`, `rtkit`, `pipewire-alsa`, `pipewire-pulse`, `vulkan-asahi` and `asahi-alarm-keyring` (the keyring of the `[asahi-alarm]` repository, named in the platform root's `keyrings`). avd-fw, libva-v4l2_request-avd, wf-recorder and widevine stay out: they are removable defaults in the runtime's Apple package list. Runtime dependencies are declared in `package()`, so the builder stages and tests the add-on without installing the desktop.

 From omacom/omarchy-mac-pkgs the package no longer ships the fork's `legacy/` copies (`/usr/share/omarchy-mac/legacy`) or the setup that retired them; pacman removes them on upgrade. The Apple pacman templates, the `omarchy-hw-apple` alias, the copies under `/usr/share/omarchy` and the platform Hyprland files that lab candidates 0.1.0-7 to 0.1.0-10 carried are gone too: Omarchy from omacom/omarchy#13362 owns the templates and the detector, and the Hyprland defaults wait for a core slot. Converting a fork or mx-mac Mac is a separate migration script, not this package.
