I recently took up Bazzite from mint and I love it! After using it for a few days I found out it was an immutable distro, after looking into what that is I thought it was a great idea. I love the idea of getting a fresh image for every update, I think for businesses/ less tech savvy people it adds another layer of protection from self harm because you can’t mess with the root without extra steps.

For anyone who isn’t familiar with immutable distros I attached a picture of mutable vs immutable, I don’t want to describe it because I am still learning.

My question is: what does the community think of it?

Do the downsides outweigh the benefits or vice versa?

Could this help Linux reach more mainstream audiences?

Any other input would be appreciated!

    NixOS is immutable and atomic, but it isn’t image-based.

    Immutable simply refers to how the running system configuration can’t be changed by simply putting a file somewhere (e.g. copy a binary to /bin, which is a bad idea).

    For example, Fedora Atomic and derivatives are image based, although they are more flexible than the A/B types like SteamOS.

    OpenSUSE MicroOS uses btrfs snapshots to apply updates atomically, and is more flexible than most image based immutable distros.

    Edit: But I don’t think those terms have a single definition, so how would you differentiate these terms?

      I’m on NixOS right now and just dropped a Chewy in my /bin, only had to sudo touch /bin/chewy.

        That doesn’t make it not immutable. /bin is not a critical directory in NixOS, only the contents of /nix are, which are immutable. /bin isn’t even part of your path by default.

          Well that was an approximation to keep it simple and disprove the given example. There are other directories in the root filesystem that are in the path by default, or used in some other critical way (like /etc). Even if they are links to directories in the nix store you can replace the link.

        Good point. I’ll have to stop using immutable and stay with atomic (and declarative).

        Interestingly /bin and /usr/bin are not in PATH by default, so /bin/chewy can only be executed by its path directly and won’t affect the systems reliability.
