The post-processors block below creates the artifacts shown here (package.box, packer-qemu, and packer_qemu_md5.checksum). I’d like to have the checksum post processor run against package.box rather than packer-qemu but I’m not finding a way to specify this. I suppose a workaround might involve using that second shell-local to do it but that seems even more kludgy given the checksum type being available.
How can I get the checksum for package.box?
