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

[tbk]

Hi,

I put all peaces together to obtain one file that can be loaded direct from UEFI Firmware (via hard disk or USB stick).
Like hire: http://harald.hoyer.xyz/2015/02/25/singl...rdcmdline/

I know this could be done during the make of the kernel with the buildin initramfs and a cmdlin in the kernel config file (CONFIG_CMDLINE).

But I was curious if a ipxe also could load the kernel.efi file.

I use Linux/x86 4.14.43 Kernel (the config file: https://pastebin.com/qeqkUssu)

To load the kernel.efi I tried

chain -ar kernel.efi

but then when the initramfs loads and failed to progress I and up in the rescue shell.
If I cat the /proc/cmdlin only kernel.efi is in there and not the content of cmdline.txt

If I load the same file via UEFI Firmware then everything is working as expected.
