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?
I think there’s just not enough people who run them. I think the closest you’ll find is the nixos crowd.
I’ve wanted to give silverblue a go, but I know how to manage my fedora install pretty well and don’t feel like taking on a new project like that when at the end of the day I just want to load up steam and decompress. I have a feeling that the majority people who want to try it are in same place I am.
Though it’s getting more and more tempting to switch since the vast majority of my data and packages are installed in my home.
Also, I use VSCode which incorporates all the toolings that I have installed and also frequently use in a terminal. For an immutable system, I'd have to use the Flatpak version of VScode, which cannot access these toolings from the host.
This isnt’t the case for NixOS. I use VsCode and all I need to do is open it by typing “codium .” after direnv loads the flake file which points to all of my dependencies. I don’t use flatpak and I’m able to provision ALL of the tooling in a way that lives with the project rather than on my machine, needing to be manually updated.
You can actually use distrobox to set up a regular version of Fedora, set up VSCode there using the official Microsoft RPM and keep all your code in there.
I dont run fedora silverblue for my maindesktop. But my laptop and my Ybox (my budget itx build for portable gaming and lan partys)
Both run fedora silverblue and Ublue my ybox runs bazzite nvidia because it has a 1060 and my laptop runs fedora silverblue 47 (i like older version better)
And they have been great. There are a few work arounds and tweaks but once you get it setup its rock soild.
my daily driver for some years now is Debian, and I have a decent setup via Ansible - everything just works for me.
Then don't change anything.
Only because there's new shiny stuff every two weeks out there in the FOSS world, doesn't mean "old" stuff isn't relevant anymore.
If Debian suits you, keep it.
My question is mostly to long term Linux users, which use Linux in a professional context
I sadly can't speak for that exactly.
I don't use Linux professionally and would rather consider myself as "noob", but maybe my input has still some value for you.

I used Silverblue now for a few months.
I broke every distro out there and SB is rock solid. If I break something (which basically never happened), I can just reboot and select the image from before. It's a huge gain of peace of mind for me to know I never have to worry about the state of my system again!
My workflow changed to using containers for everything.
As I said, I'm pretty much a "casual" user, so Flatpaks cover 99% of my needs.
If I need some CLI program or something not available on Flathub, I use Distrobox, which gives me access to every distro and integrates perfectly.
Issues: nothing major yet.
If a containered program shouldn't work, I can always install it natively per rpm-OSTree.
Reboots aren't an issue too.
I shut down my PC anyway, so I don't care. Updates get installed and staged in the background, and I boot into a new image everyday.
I never get forced to reboot, even less than on normal Fedora.
Usually, on a mutable system, you should offline-install and reboot your PC anyway for safety and better stability on the runtime.
The only thing that didn't work for me are VPN clients, but the integrated Gnome solution works fine for me too.
Oh, and many install-scripts don't work/ aren't available for SB aswell.
Most might work, but nobody took time to write one, since they need some other approach than Debian or Fedora.
I really recommend you to check out uBlue, it's a great project and really "the future".
It uses the rebase-feature, which enables users to make their own custom images, similar to Nix.
I for example use uBlue-Silverblue, which comes with some QOL-stuff pre-enabled. You can also install a SteamOS clone, images with integrated Nvidia-drivers, "unsupported" DE- and WM-spins, and so on there. With one command. And you can swap out the base anytime you want on an existing system.
Would I recommend you SB or any other immutable distro?
Theoretically, 100% yes! Practically, in your case, no.
Stick with Debian if it fits you. Look into Distrobox if you want. See, if most stuff is in your home-directory, or if you prefer uncontainered stuff.
If the pros outweigh the cons for you, then install it the next time when you have to anyway (new hard drive, etc.).
But you can also wait a few years until immutable OSs get more widespread and mature.
Edit: I just looked up what Ansible is. In that case, NixOS would be fabulous! uBlue is relatively new and probably not as mature.
If you like to install a system reproducible, just share the nix-config and apply it on another PC. But you have to get into it first, which might be complicted and time consuming. It still should be worth it.
I agree with your advice, to not jump ship when everything works and that the new stuff doesn't have to be better.
For Silverblue, I see the potential that it is an improvement over Debian for me. I used Fedora some years back, and it was always the distribution with my favorite community, besides its technical excellence. I played around with openSuse's Aeon/MicroOS, and I love the update system for immutable systems. (Just reboot and be done with it.)
So, where I hope Silverblue will be a clear improvement for me:
Immutable/automatic updates
Updated software packages (No, not interested in running testing or unstable)
Fedoras polish for Gnome users
Containers for work stuff (At the moment I use whole VMs, which was one of the reasons to automate everything with Ansible)
The nice thing for me is, if it doesn't work out with Silverblue, I can setup my Debian system via Ansible in no time.
Debian is great when you're a bit more conservative and want to not change as much, and Fedora is more leading edge for new technologies.
They implemented, for example, Wayland, Pipewire, and much more, as one of the first.
So, where I hope Silverblue will be a clear improvement
Don't fixate to much on SB. There's also VanillaOS out there, which is/ will be based on Debian and aims to be as user friendly as possible.
Many of the pros are universal to most immutables.
Containers for work stuff (At the moment I use whole VMs, which was one of the reasons to automate everything with Ansible)
You can already use Distrobox or Toolbx on Debian.
But they don't replace VMs and are more similar to Flatpak, giving you mostly runtimes and dependencies, but the host OS is still perfectly accessible.
Fedoras polish for Gnome users
Fedora doesn't polish Gnome. They only provide vanilla desktops, KDE for example is also pretty much unchanged.
Difference is, that most other distros modify their DEs, which isn't what the creators intended.
This is why, in my personal opinion, Gnome on Ubuntu sucks for example
i'm running kinoite 39, since a few months, and honestly i'm pretty happy, there is a few bugs of theme consistence that was fixed(and because i'm in beta) i was already running everything on flatpak anyway so not much change, and toolbox is so integrated that i can install software there and use it instantly, so not needing to rpmostree install and reboot everytime, kde is not so instegrsted as gnome so global theme needed to be installed manually, and i changed a few configs to shutdown my laptop after i close the lid, so i can open it and have the system updated automaticly, i don't think it's perfect, i needed a lot of reading to trully know how my system works(and why i can't change the /usr for example) but it's fun to learn and i can install anything inside toolbox that i know not going to fuck my system lol
I’m running silverblue, which works pretty well for a few years now. The only limitation I’ve encountered is getting non-packaged software to work, such as drivers and accompanying software for my racing wheel.
My workflow hasn't changed much except I now find myself writing shell.nix files in my projects instead of having various compilers and build tools installed in my config itself since adding a random one-off dependency for a project is tedious if it doesn't get added to the correct environment variable or something. Ultimately, this is really a benefit tho as it means I have a reproducible dev environment that can be shared with anyone else.
It also simplifies a lot of configuration stuff with sane defaults making it way easier to spin up things that might take a little bit of messing around, e.g. different desktop sessions (currently, I mostly use i3 and GNOME Wayland + Pop Shell, but I've experimented with others).
It's more about how clear it is for me to get to my workflow. The Nix system (language, package manager, and OS) is really just beautiful once you get your head around everything.
I've been on Nix now for a few months coming from Fedora (1 year) and before that Arch (3 years), and I've loved every second so far. I use it for both work (embedded software engineer) and personal. It feels like the last thing I'll ever config
These distros are all about making thing that were easy into complex, “locked down”, “inflexible”, bullshit to justify jobs and payed tech stacks / some property solution existence.
We had Ansible, containers, ZFS and BTRFS that provided all the required immutability needed already but someone decided that is is time to transform regular machines into MIPS-style shitty devices that have a read-only OSes and a separate partition for configs. All in the hopes of eventually selling some orchestration and/or other proprietary repository / platform / BS like Docker / Kubernetes does.
I have to disagree with you on that. You’re missing the point entirely.
It’s not about making something easy into something complicated. It’s about making something that is reliable and reproducible.
Saying it’s just bs to justify jobs, sales, etc is like saying we already have widget X therefore it’s stupid to use widget Y. You’re missing the reasons why someone might need a widget that does something different than widget x.
No one is (should) be saying one is superior to the other. It’s different technology and methods to get to the same goal. That is a working system that consistently and reliably produces results that are required.
So yes, there’s different ways of managing those systems but that’s not a bad thing or is it needlessly complicated for no reason or benefit.
There’s a lot of reasons why someone would choose or need something like nixos or sliverblue. There’s also lots of reasons someone would choose not to use them
Thank you for your reply, although I have different experience/use cases.
For example, I have an old laptop as a dedicated multimedia machine. An immutable desktop is the far better option for me, as an end user. Everything works OOTB and updates happen silently on reboots.
The same is true for a lot of people which only need a browser, IMHO.
No orchestration or proprietary repository needed.
Any distro with BTRFS works for your use case and will be easier to deal with.
No orchestration or proprietary repository needed.
Yes, but guess what happens whenever people popularize immutable distros as the next hype in tech that will make everything better? You get yourself into a totally unreasonable and avoidable ecosystem just because those systems won't cut it for most use cases.... same that happened with Docker/Kubernetes.
Let me fix that for you: we already had reliable and easy to use tools, let's popularize now an alternative solution that is more complex and inferior.
You clearly haven't had any experience with immutable distros before the current hype. Let me tell you something, immutable systems aren't a new thing we already had it with MIPS devices (mostly routers and IOTs) and people have been moving to ARM and mutable solutions because it's better, easier and more reliable.
Ansible isn't a good solution for reproducibility, since when you remove something from the playbook and redeploy, that old state will still be active.
