Not the original commenter, but no need to apologise my friend. Nice work. Learning tip from me: give PEP 8 a read and save it for reference somewhere. It’s the standard for how to format Python code, and future you will thank you for internalising it early on in your Python journey

And how does that work? How do you unmount the root directory of a live system and invoke a script?

Nextcloud is a FOSS fork of OwnCloud. Both projects are great in their own way, hugely successful and serve a lot of people very well. They just moved in different directions.

This is just one example of many. Ability to fork is super important to ensure that projects stay open source, like in this example.
