the signed template together with the binary package(s) containing the unsigned
files form the input to our secure boot signing service.
the signed template consists of
- files.json (specifying which files are signed how and by which key)
- packaging template used to build the signed package(s)
the signing service
- extracts and checks the signed-template binary package
- extracts the unsigned package(s)
- signs the needed files
- packs up the signatures + the template contained in the signed-template
package into the signed source package
the signed source package can then be built in the regular fashion (in case of
the kernel packages, it will copy the kernel image, modules and some helper
files from the unsigned package, attach the signature created by the signing
service, and re-pack the result as signed-kernel package).
