Why not call the recipe systemd-ukify then? systemd-boot doesn't provide more than that.

Then, when using ukify, one needs to have the .efi binaries from target systemd recipe which
for aarch64 are:

/usr/lib/systemd/boot/efi/addonaa64.efi.stub
/usr/lib/systemd/boot/efi/linuxaa64.efi.stub
/usr/lib/systemd/boot/efi/systemd-bootaa64.efi

and these could IMO be in a systemd-boot binary package because these files are not needed
in the main systemd binary package and rootfs.

The recipe itself looks neat and small, thanks!

For secure boot sbsign-native would be needed, but maybe a separate issue.

Cheers,

-Mikko
