ppc64le ISO does not contain a kernel
The alpine-standard-3.14.0-ppc64le.iso
image does not contain a kernel:
thomas@hoth /Volumes/alpine-std 3.14.0 ppc64le
% cat boot/grub/grub.cfg
set timeout=2
menuentry "Linux lts" {
linux /boot/vmlinuz-lts modules=loop,squashfs,sd-mod,usb-storage,ibmvscsi quiet console=hvc0
initrd /boot/initramfs-lts
}
thomas@hoth /Volumes/alpine-std 3.14.0 ppc64le
% ls -l boot
dr-xr-xr-x - thomas 15 Jun 16:35 grub
thomas@hoth /Volumes/alpine-std 3.14.0 ppc64le
%
Not only is there no kernel to boot, there is also no linux-* package. As there is no kernel package either (see https://pkgs.alpinelinux.org/packages?name=linux*&branch=v3.14&arch=ppc64le), this seems like it might be caused by #12767 (closed).
