(Get the code!)
This appears to be intended behaviour. The intel-microcode package is prepending an uncompressed CPIO archive, containing just the microcode for the local processor, in front of the existing compressed initramfs archive.
This is (apparently? in some versions?) supported by the kernel as an input format to allow the microcode update to be applied early in the boot process.
Attempting to unpack the resulting combined image with `cpio` will only show the contents of this first archive, and not the second one appended after it. However, if you run `lsinitramfs` on the archive, it will list the contents of both.
