Bug#982227: gnome-boxes: please stop using cdrkit

[Chris Hofstaedtler]

Package: gnome-boxes
Version: 3.38.2-1
Severity: important

Dear gnome-boxes Maintainers,

your package depends on genisoimage, built from cdrkit sources.
cdrkit does not have a path forward, please switch away from it
rather soon. I'm told xorriso and libburnia are alternatives and are
alive and doing well.

It's been suggested cdrkit should not be in bookworm.

Chris
