# This script is our half-baked ad-hoc reimplementation of a minimal

(BTW, I think the best fix here is to generate a minimal initramfs that mounts the host (container) filesystem via virtiofs/9p. Then we really don't need supermin at all, we can use systemd etc. when we're building the ostree-based disk image, etc.)
