And that's exactly how it should be. I'm not sure about jessie's kernel,
but stretch one has ext support built as a module (CONFIG_EXT4_FS=m).
Meaning - if you want to boot from ext2/ext4 filesystem you'll need
initrd. This qemu invocation does not supply one.

I'm genuinely surprised that such method worked for them.
