Clara Kowalsky July 8, 2024, 12:47 p.m. UTC 
In case of ext*, this detects and fixes file system errors in the
partition device before doing the partition mount.
If the partition turns out to be broken, the factory state is recovered.

Why do we need to put the recover logic into a function? If the script
itself is the interface, we can save a lot of boilerplate and can also
avoid that sourcing with the shellcheck annotation.

I suggested the function to allow an way to overwrite the recovery logic
in case another behavior is required by downstream.

You would call the script directly?

Then I'm not yet getting the idea completely yet: You are already
testing for the existence of that script and only source it when
available, and the default function is "do nothing". So, what is the
benefit of that compared to testing for the script directly where the
function is called now?
