If they’re asking about this script, they don’t know to even ask that question. The fact is that immutable distros pair best with fixed and very mainstream hardware, which we don’t know this guy has or not.

I think these types of discussion as are always a mess because it is difficult to gauge the user’s knowledge and needs based just on a single, often limited post, but I also think that many Linux distros are for a specific use case or set of use cases, such as the immutable ones.

I think it best serves the OPs of questions like this to ask them follow-up questions before recommending something like that, because they can be quite restricting. It is awesome you’ve never had to ostree, so you must be exactly the type of user that immutable distros are for, but please do understand that what they mean by immutable is “you can’t mess with the kernel at all without a performance impacting ostree”, so asking whether that is a dealbreaker is a good move.
