with this patch exlinux.conf boot item looks like
label l0
        menu testing
        linux /boot/vmlinuz-5.15.16-arm
        initrd /boot/initramfs-5.15.16-arm.img
        fdtdir /boot/dtbs/5.15.16-arm/

So extlinux.conf support is
https://systemd.io/BOOT_LOADER_SPECIFICATION/ so please work with
upstream there as well to get kaslrseed added and documented.  Thanks!
