Loading a combined kernel, initramfs, and boot options as direct loadable efi stub

[tbk]

Hi,

I want to load a combined kernel, initramfs, and boot options as direct loadable efi stub. There fore I prepare the kernel.efi as follows:


objcopy \
--add-section .osrel=/etc/os-release --change-section-vma .osrel=0x20000 \
--add-section .cmdline="cmdline.txt" --change-section-vma .cmdline=0x30000 \
--add-section .linux="vmlinuz-linux" --change-section-vma .linux=0x40000 \
--add-section .initrd="initramfs-linux.img" --change-section-vma .initrd=0x3000000 \
/usr/lib/systemd/boot/efi/linuxx64.efi.stub kernel.efi

If I load the kernel.efi direct with the EFI bootmanager everything seems fine.
But if I load the kernel.efi with iPXE the cmdline is somehow missing (the /proc/cmdlin is
empty ... only kernel.efi is in there)
