Experiences using immutable Linux desktops?

I am playing around with Fedora Silverblue and openSUSE Aeon and I really like the painless updates.

Still, my daily driver for some years now is Debian, and I have a decent setup via Ansible - everything just works for me.

My question is mostly to long term Linux users, which use Linux in a professional context and jumped from a distribution like Fedora, Ubuntu, openSUSE or Debian to NixOS, Silverblue, Aeon etc.

What is your experience? How did your workflows change on your immutable Linux distribution? Did you try immutable and went back to a more traditional distribution - why? How long are you running the immutable distribution and what issues and perks did you run into?

  • This. It allows me to be incredibly flexible and granular about exactly which software is installed in which environment. I could dream up the most obsolete (or vaporware or anything in between) tech stack imaginable and bind that to a flake and lock it then not have to worry about the rest of my system being contaminated with those unusual dependencies. It’s like what Docker dev environments and devcontainers are attempting to do but 1000x more elegant and reproducible.

    • Lol... as someone who jumps around between toolings all the time, this is anything but "flexible" for me.

      I might write an app that uses web tech for the frontend and golang for the backend, and suddenly decide to throw in a flutter version for mobile.

      But if it works for you, great.

      • Lol!

        Maybe I’m reading that wrong…if not, I’m kind of dumbfounded how you can somehow take away from what I said that this technology doesn’t make that 1000% easier than your current method.

        Say I wanted to suddenly throw in a flutter version for mobile, I could just add a flutter input and output into the flake and suddenly I’d have that tooling.

        I suspect you misunderstand how it works.

        How does your old school manual install method make that easier?

        Full disclosure: I honestly don’t care if you use it one way or another. I’m just hoping to educate you (or anyone reading along) about the true nature of the widely misunderstood tech we’re talking about.
