@Prototik Thanks for the implementation, seems to work!

One thing, bootctl set-default does not work, when someone doesn't use systemd-boot. This currently prints an error message when generating the UKI. That's why I removed it in my patch. But I don't know if there is a good non hacky way to set it automatically (if the path is dynamic).

@jonas-w latest update adds option to customize UKI image location, now you can use this package without custom patches to store UKI for UEFI default location, can you try it and give some feedback if you wish?

If someone wants to use the EFI directly without systemd-boot, I created a patch which installs the efi to EFI/BOOT/BOOTX64.efi if you set it as default kernel package otherwise to EFI/BOOT/BOOTX64-$pkgname.efi. Feel free to use this, but with no warranty.
