Hi,
I integrated this patch into another tree without the packages feed.
Then I get errors about missing dependencies:
WARNING: Makefile 'package/boot/systemd-boot/Makefile' has a build
dependency on 'python-pyelftools/host', which does not exist
WARNING: Makefile 'package/boot/systemd-boot/Makefile' has a build
dependency on 'python-jinja2/host', which does not exist
and later python3 is missing:

No easy fix :-) I think it will be difficult to integrate all the
dependencies into openwrt in order to compile the entire systemd with it...
Have you thought about integrating the boot cmdline into the kernel
(CONFIG_CMDLINE) and just put the kernel to /boot/efi/boot/bootx64.efi ?
Or the new UKI-Format?
Best regards,
Stefan
