Together with the ARCH specific BJC it will maybe compress a little bit better

Thank you for contributing to Minimal Linux Live! :)

Thank you, that's a really nice observation!

I'll update the initramfs generation as per your suggestions shortly.

I've added the crc32 check, but the --x86 optimization seems to be breaking the QEMU test, so I'm leaving it for now.
