I’ve been feeling gushy about my setup lately, I think I’ve finally found my home on Linux. For decades I’ve distrohopped each year and never was really happy with it all, but Fedora Atomic has changed that.
Some things I can do with Fedora Atomic that I cannot do with other Linux distros:
-
I can rebase to Bazzite for gaming performance when I feel like having a long gaming session.
-
I can rebase to Secureblue when I think I will not be gaming and would prefer a more secure linux setup.
-
I can update my system and not have to worry about special instructions, its extremely stable. Many times in the past, running a small ma-and-pa distro with most things pre-configed for performance would end with it breaking after a couple of major updates. This isn’t true for configs like Bazzite and Secureblue, they are remarkably stable across many major updates due to how rpm-ostree functions.
-
Distrobox and Flatpak are more than enough at this stage for most programs and they help you avoid making too many alterations to the base image, greatly speeding up the swaps between major images.
The kicker? Your user configs and home files are never changed when you ‘image hop’. It always feels like you just installed a fresh distro whenever you upgrade, and the performance benefits are noticeable. You don’t have to tinker and do the same changes over and over, its all handled for you by rpm-ostree.
10/10 this is the future of Linux. I hope for a future where I can rebase entire Linux distros while maintaining my configs with one simple command, but for now, Fedora Atomic is fantastic.
The downsides:
-
There is one major downside, and its that all of your system files are read-only. Personally, I’ve found a dozen ways to get around this, it requires thinking inside the Distrobox. It is a notable issue for many people, though. This means you cannot make specific tweaks without making a whole new image for yourself. Though in practice, I have found the ecosystem has grown a lot. Other people have already made the best tweaks available for you with only a few simple commands.
-
Rpm-ostree also is slow to update because its essentially building a whole git tree to make sure your updates never break and are as stable as possible. You also have to reboot each time you alter it, which can be annoying, but if you stick to flatpaks and distroboxes, this issue is mitigated significantly.
I appreciate your mentioning the downside. I am way too much of a tinkerer for a read-only root to be acceptable for me, but I’m glad you found something you like.
10/10 this is the future of Linux.
I hope it’s a future of Linux, not the future. I’m not a fan of atomic distros, mostly because if their reliance on flatpak and the like
I think this approach is going to fair the best for mainstream adoption (i.e. Windows refugees). So I would agree that the “future” is going to involve immutable distros as a large, possibly majority, of all Linux installations.
I agree. Fundamentally, you still need good distros to plug into distrobox to make swapping between immutable systems quicker. In general I feel like running Fedora Atomic has really opened my eyes to the possibilities of using distrobox + boxbuddy to get quick and easy installs from AUR or something and saving annoying-to-make configs in a backup file somewhere.
Atomic is also absolutely fantastic for throwing on an old computer that you use rarely. The update will not break after letting it sit for so long without them.
My biggest disadvantage of atomic distros is flatpak reliance too. I hate how bad the terminal interface for managing/running flatpaks is. But I still hope that this will improve in the future.
I feel like flatseal mitigates this a bit but I do agree that flatpaks have room to improve. Particularly with making sure flatpaks are verified against the open source projects they are made from.
Sounds like a good way to do Linux phones.
An image-based system would be the bare minimum to achieve basic security, but there would still be so many security issues compared to Android and iOS, that I don’t think Linux phones are worth putting time and development effort into.
AOSP is a fantastic base for open source mobile systems. The FOSS mobile development community should rather shift its focus to AOSP, develop a good understanding of it and get familiar with the code, instead of trying to reinvent the wheel with mobile Linux distros.
We really cannot rely on aosp because while google in control of source code and not take any contribution to code we have in relastic case "u permitted to read code and clone " and back feedback and as result we will have aosp as google wish it only for their own profits and theirs views how they see it.I am not even talking that they not use any enforce policy that manufactures cannot lock bootloader without ability to unlock
Honestly, I haven’t considered this before but it sounds like a great idea.
I think i’ll be heading back to Pop!_OS for my main rig. While i like Bazzite, i can’t get VR to function on it, or get my 5.1 surround sound system working. I think it’s great for a hand held, but not for a main rig.
You might want to look at the ujust commands on Bazzite, they have some options for setting up surround sound and VR I’m quite sure. I have a pretty simple setup personally so I’ve never used those things.
wonder how it is on aarch64, I might try it
Distrobox and Flatpak are more than enough at this stage for most programs
Maybe for you, but personally I could never get by with only that. I have zero interest in atomic distros. To me they look like an inferior version of NixOS, which I have yet to fully wrap my head around. Until then I’ll stick to Arch (BTW)
Same here. I have and will always periodically reinstall no matter which OS I happen to be using. Arch is the only distro that keeps me coming back because installation and setup is such an active process. Every time around I learn something new and get more effecient at the process, which is so much more rewarding than filling a few boxes and waiting on a progress bar as is the case with most distros I have experienced.
It’s not the future… it’s the present for all users running mobile linux-based computing devices called Android smartphones. The paradigm is very similar to Atomic distros. As for what the future might hold for linux, that remains to be seen.
The Atomic UX has proven very popular with mainstream users running by Steam Deck and similar devices as running Bazzite. They may not be aware how they are built, they just know it just works and that’s all they need.
As for the maintainers, containerized development removes a lot of development time, provided they have experience in cloud native development environments. Old school developers get annoyed by this constraints.
All in all, it’s just another alternative, don’t diss it out of fear it might take over the Linux scene… let others have what they need, provided by Linux and open source software.
Why not just run a hypervisor and use containers?
