FYI, there are cloud-init and tiny-cloud. It looks like you are trying
to use tiny-cloud. doing that from pxe boot is currently not supported,
but should be relatively easy to fix.

Could you please add an issue to
https://gitlab.alpinelinux.org/alpine/mkinitfs/-/issues

I think we can make this work without needing any apkovl, we simply
need to make the initramfs enable tiny-cloud when it finds `ds=3D...`,
similar to what we do when it finds cidata disk label.

Thanks!
