[Bug 1821640] Re: Missing pattern for linux-image-unsigned keeps autoremovable kernels on the system

[Balint Reczey]

IMO adding two patterns than keeping the rule of not adding patterns that would only cover versioned kernel packages that could not be installed by installing meta packages from the archive is worth it due to the reduced complexity.
Alternatively I can add exceptions for those patterns in the autopackagetest to ignore the covered packages.
