Linus: Are you going to say the AI word?

I’m not going to say the AI word, unless you want me to.

No, no, no.

Hahah

You are replacing partitions with subvolumes, as such you have to make these operations on the btrfs filesystem (so as others have already written, deleting the subvolume instead of re-formatting the partition).

Usually, when games and programs natively support 3rd party mods/plugins its done so through a defined API - a modding API - just a bunch of functions made by the devs that allow you to register new stuff, change/override what already exists, react to events, … Example https://lua-api.factorio.com/latest/

Lua is often used as the language for the mods because it’s really easy to embed into a program (most games are done in compiled languages) and so creates a “sandbox” - you can only really call what the devs make available for the lua scripts.
