For once I feel a little out of touch after I took a bit of a break from following the news to focus on studying, and suddenly everyone is talking about immutable distributions. What are they exactly? What are the benefits and the disadvantages of immutable systems?
They also separate concerns better than classical distros. Executable binaries & libraries are separate from configuration which is separate from data. It makes backups much simpler, makes configuring new machines easier than something like Ansible, etc.
