Building audiobooks on (Debian) Linux in the m4b format is actually possible and doesn’t have to be a pain. I’ve found numerous recipes with shell instructions, but having a nice simple app to handle the building of the books seems much easier. Most of the apps available for Linux seemed to be in a pre-alpha state, but after a few experiments I’ve settled on m4baker, which - while a bit rough - actually seems to do the job just fine.
Running a modern IT platform is rarely an easy nor isolated task. Most platforms consist of a fairly large number of components ranging from OS level to 3. party libraries and components added in the user interfacing layers - and adding numerous integrations does make it an interesting challenge to quickly identify and correct bugs and errors. While the system complexity does pose a challenge is surely not an impossible task, as several tools exists for most - if not all - platforms to allow instrumentation of the platform and utilize the instrumentation tools to handle the platform and identify issues quickly.
