And of course, the law of asking questions on the internet is verified, and I find the answer minutes after asking a thousand people. A Linux initramfs is a concatenation of cpio archives, so I can just `cat microcode.img initrd.gz >initrd`, embed that in my unified image, and everything should just work.
Please let me know if I'm wrong, and otherwise - thanks for being my rubber ducks!

Hi,I'm exploring systemd-boot and secure booting for an Arch Linux install. To get secure boot working right, I need to build a unified kernel image that I can sign. However, I also need to pass 2 initrd images into the boot process (one for CPU microcode, and the proper OS iniramfs).But, AFAICT from reading the EFI stub source code, I can only have one ".initrd" section in my unified binary.Is it possible to have multiple initrds in a unified kernel image? If so, how do I construct the unified image? If not, can you suggest an alternative that gets me my microcode and my OS initramfs?Thanks!- Dave
