scripts-arm — aarch64 delta for the x generations engine

ARM-only companion of equislinux/scripts (the x provisioning payload and CLI). scripts is consumed read-only at a pinned commit; this repo owns the aarch64 delta and builds the package that replaces x-scripts on ARM systems.

Why a separate repo

The generations engine is x86_64-shaped: it globs /boot/vmlinuz-*, pairs initramfs-<pkgbase>.img and reads /usr/lib/modules/<rel>/pkgbase. Arch Linux ARM's linux-aarch64 installs /boot/Image(.gz), initramfs-linux.img and no pkgbase file. Keeping the delta here means equislinux/scripts (and therefore x86_64, WSL and everything else) is never modified; every ARM change is a patch over a pinned upstream, reviewed in isolation.

Layout

vendor/scripts.sha                    pinned commit of equislinux/scripts
patch/generations-aarch64.patch       the ARM delta (Image, pkgbase fallback)
build.sh                              pin -> patch -> x-scripts-arm package
out/                                  built packages (gitignored)

Build

./build.sh                      # needs aarch64 + makepkg (or the x-arm Docker builder)

Produces out/x-scripts-arm-<ver>-any.pkg.tar.zst (identity derived from the upstream packaging/PKGBUILD: provides/conflicts/replaces x-scripts).

Install on an aarch64 X system:

sudo pacman -U out/x-scripts-arm-*-any.pkg.tar.zst
x gen new --reason test

Contents of the delta

• xkernel.sh: linux-aarch64 in the known-kernel list; a single xkernel_pkgbase_of() fallback (ALARM ships no pkgbase file), restoring x kernel listing/removal safety on ARM.
• xgen.sh: archives /boot/Image(.gz); synthesizes pkgbase=linux-aarch64 for kernels.tsv; legacy pairing accepts Image*; the dedupe check compares Image* too.

Every fallback is conditional on uname -m == aarch64 or on files that Arch x86_64 does not install, so the delta is inert off-ARM by construction.

Sync policy

• Bump vendor/scripts.sha deliberately when pulling upstream changes; re-apply the patch and re-run the upstream test suite on the patched tree (bash test/validate.sh, headless sections) before publishing.
• Publication: the package belongs in [x]/aarch64 (published from equislinux/x-arm-repo); the installer integration lives in equislinux/x-arm (overlay).
