[PATCH v5 0/3] Add byhand script to perform code signing for secure boot



Publish the signature of packages automatically when the package is processed based on previous
package prepared by the maintainer with all the efi images and linux modules.

The maintainer prepare a ${package}-code-sign_${version}_${arch}.tar.xz with all the efi images
and/or linux modules, and a changelog file. When processing the package from the queue, the
byhand-code-sign script is called, read this .tar.xz package, sign all the efi or modules inside
it and publish a tarball with all the signatures at
$ftpdir/dists/$suitedir/main/code-sign/$(sha256sum "$IN_DIR/changelog" | head -c 64)_$ARCH.tar.xz
This signature are then retrieved by the maintainers of the *-signed packages (e.g. linux-signed,
grub2-signed, fwupdate-signed) to construct the *-signed versions.

NOTE: The maintainers of the main package and the -signed package will have to coordinate their
uploads to reduce de propagation delay of a security fix to be incorporated in the -signed package

Script used for testing byhand-code-sign-user:

Changes since v4:
