The Omarchy payload is architecture-independent, but the package is not.
On x86_64 omarchy pulls the Limine + mkinitcpio hook + Snapper boot stack;
on Apple Silicon the system boots through m1n1 + GRUB from the Asahi
packages on Arch Linux ARM's kernel, so that stack does not apply, and
Wi-Fi on the Broadcom parts needs the iwd backend. The shipped /etc tree
differs too: mkinitcpio reads every file under /etc/mkinitcpio.conf.d/,
so shipping omarchy_hooks.conf on aarch64 injects the Limine hooks into
the Asahi kernel's initramfs, and the zram/zswap/oomd drop-ins and the
zram-tuned vm.* sysctls belong to the x86_64 memory stack.
makepkg only honours depends_<arch> and optdepends_<arch> on
arch-specific packages, so arch=('any') becomes ('x86_64' 'aarch64').
backup=() has no arch-suffixed form, so the x86_64-only entries are
appended under CARCH and each of those paths is removed from the aarch64
package in package(). The x86_64 package keeps exactly the contents it
had; only its filename suffix changes.
The install scriptlet applies the hardened cups-files.conf on every
platform, then on Apple Silicon keeps the Arch Linux ARM system identity
(/etc/os-release stays the distribution's symlink) instead of the
etc-overrides. The -dev pair carries the same change so the pairs stay in
lockstep.
Stable-track counterparts of the -dev packages. Source is pinned to a
single shared upstream commit with a real sha256 (pacman 7 validates
checksums on commit-pinned git sources), versioned per the attached-rcN
convention so vercmp orders rc1 < rc2 < final. Seeded at 4.0.0rc1 from
the quattro tip because no upstream 4.x tag exists yet and the packaging
requires the quattro tree (v3.8.x has no shell/ or etc/).
Both packages stay off the fast ring: RCs publish to edge only; stable
receives finals via bin/repo migrate.
