Linux

I need to run immutable distros more, and I need to figure out how to roll my own images.

Desktop side, I need certain things in the base image rather than adding more layers or using a container. Things like rsync, nvim, git, curl, lynx, etc.

Would immutable distros help reach more desktop audiences? Perhaps. It’s more about applications though. The biggest help has been electron apps and the migration to web apps. The Steam Deck is successful because it has applications people want.

Server side, they look really promising for bare metal servers. Provided, there is an easy way to compile custom images. Being able to easily rollback to a known good image is very enticing, as you point out.

TL;DR: My desktop PC uses EndeavourOS and the only immutable experience I have is SteamOS 3. I can't say one approach is better than the other, but I like having the newest software and packages in my system. And that's best provided with a rolling release. I also think that sandbox systems like Flatpak and the several alternative installation methods besides the system package manager is an added complexity for a new user in Linux.

I don't mind using an immutable system (BTW another term that describes this kind of system is Atomic, which comes from Fedora), as long as it is designed around it and works well. The only immutable system I use is on my Steam Deck with the pre-installed SteamOS 3. My generic desktop personal computer is using an Archlinux derivative EndeavourOS with a rolling-release, where I have much greater control over the system.

Both systems have their strengths. I don't think that my mutable and always up to date system is breaking more often than the other system. The best part of it is, its always up to date and I get the newest applications. I try to not use much Flatpaks or AppImages (but do for certain apps, where I have no other choice for ease of use). And an immutable system naturally basically asks me to use Flatpaks and other user space package formats that is not handled by the distribution itself.

Even though I have some thoughts on it, I am not excluding one approach. Many say that immutable distributions are good for new users to Linux. I think this adds some complexity and problems, because they need to use sandbox systems like Flatpak. And that's if they know that they are using Flatpak, because sometimes the app distribution gives options like AppImage and custom installer scripts as well. This is all confusing for someone who just starts with Linux. On top of it, the sandbox of Flatpak requires some additional setup and configuration for some apps, to access certain hardware or filesystems in example.

All in all, I tend to like the traditional "mutable" distribution system as a rolling release model the most. But I'm an not excluding any other and would use a good "immutable" one; I just didn't try any other than the one in my Steam Deck.

I wonder if you can download Apparmor and Apparmor-d on mutable distros, But I faced issues of bwrap and I couldn't find a SELinux equivalent for Apparmor-d i tried allowing Bwrap but it didnt work so i uninstalled Apparmor.

Could you share some pics (without anything private ofc) of bazzite? I wanted to try it but I couldn't use it as live distro. My main problem is arch because I'm used to apt and I find pacman or whatever it uses difficult for me (nothing I can't learn ofc)

I love the idea of getting a fresh image for every update

What do you mean? Thanks

I am a huge fan of immutable distributions, not for my personal daily driver but for secondary systems like my living room/home theater PC.

what does the community think of it?

Everyone has their own opinion, personally I think they're a great idea and have lots of great applications. But just like rolling vs non-rolling release it's a personal and application dependant choice.

Do the downsides outweigh the benefits or vice versa?

Again, depends, for my personal computer I wouldn't use it because I think it could get complicated to get specific things to work, but for closed hardware like the Deck or even a fairly stable desktop used as a gaming system it's perfect.

Could this help Linux reach more mainstream audiences?

It could, it can also hamper it because people might start to try solutions that only work until next boot and not understanding why, or having problems getting some special hardware to work (more than it would be a mutable distro). But there is a great counter to this which is that once it's running it will be very difficult to break by user error.

At the end of the day I think it's a cool technology but that people should know what they're getting into, just like when choosing rolling vs non-rolling distro, it's not about what's better, but what suits your needs best.

I don't mind flatpaks in a pinch, but having to use them for literally every app on my computer is an unreasonable amount of bloat.
