Calling XZ on the result as we do now=20 is still worthwhile but not efficient.

Cake will be served once I (or someone else) get squashfs boot=20 working reliably. We'll no longer *have* an =E2=80=98uncompressed=E2=80=99= ISO at=20 that point, we'll boot directly from XZ. But that first requires support for (real) unencrypted /boot.
