+This project provides a script for making customized https://alpinelinux.org/[Alpine Linux] disk images for x86_64 and aarch64 footnote:[Supported since Alpine Linux v3.19. See <<aarch64-old>>.] virtual machines.
 You can choose between BIOS mode (using https://syslinux.org/[Syslinux], only for x86_64) and UEFI mode (using Linux https://docs.kernel.org/admin-guide/efi-stub.html[EFI stub]).
 It’s quite simple (400 LoC of shell), fast (~32 seconds on GitHub Actions), requires minimum dependencies (QEMU and filesystem tools).
 
-IMPORTANT: aarch64 currently only works with the kernel (linux-virt or linux-lts) from Alpine edge! See <<aarch64-v3.18>> for more information and a workaround.

 TIP: Don’t need VM, just wanna chroot into Alpine Linux?
      Try https://github.com/alpinelinux/alpine-chroot-install[alpine-chroot-install]!

-=== Create Alpine v3.18 (latest-stable) image for aarch64

-The Linux kernel (_linux-virt_, _linux-lts_ or _linux-edge_ package) in Alpine v3.18 and earlier doesn’t have https://cateee.net/lkddb/web-lkddb/EFI_ZBOOT.html[EFI_ZBOOT] enabled, so EFI stub cannot load a compressed vmlinuz.
-We backported it to v3.18, but then we had to revert it due to a problem with Grub (see https://gitlab.alpinelinux.org/alpine/aports/-/issues/15263[alpine/aports#15263]).
-
-If you want to build an image with a stable branch of Alpine Linux, you can, but you must install the kernel from the edge branch.
-This is relatively safe because the kernel package doesn’t have any dynamic dependencies and the version in v3.18 and edge will be in sync at least until v3.19 is released.

-. Run {script-name} with the options `--repositories-file ./repositories` and `--packages linux-virt@edge` (or `linux-lts@edge` if you use `--kernel-flavor lts`).
