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?

    Immutable distros are locked-down versions of the traditional operating systems. Literally.

    In the normal traditional world, you can use the package manager to remove python as a system package and all its dependencies if you so wished. You could rm -rf / too.

    With immutable, the whole filesystem is on ro mode. Every system program that a user needs is bundled by the OS and no other changes can be made without breaking the model.

    This model of having the OS immutable means less chances of malware getting persistence, high systems availability and reproducible environments since the OS controls the state of the versions available and makes this state available to all users of the distro.
