Ah indeed.

I think we can continue to uselessly build the cpio archive. As I said,
my long term proposal would rather be to switch all tests to use ext2 +
a hard drive. We still need to define an image size, but at least we
can a hard and clear error if the filesystem no longer fits rather than
these weird errors caused by initramfs being partially uncompressed.

Thanks for the review!
