Thanks very much for the detailed response - this was very insightful!

The biggest issue with immutable OSs is the lack of containerized apps. Most devs simply don't distribute their apps in flatpaks etc. Install fedora atomic. Fist think I want to do is install xpipe to manage my servers. Can't be don't in an unprivileged flatpaks. Great layer it on.

Let's try seafile next to sync my files and projects...the flatpak is maintained by a random volunteer and most up to date version is from a year ago. Great, layer that in as well.

Let's install a command line tool, before it was 1 line, now it's a whole lot of googling only to discover that the best way is probably to just have a whole other package manager like brew

The concept is great and it has lots of potential, just it will only work if devs start packaging their stuff in a format that works with the new paradigm (containers)

astOS and Arkane Linux too.

For me:

• atomic updates
• reproducibility
• (to some degree) declarative system configuration
• increased security
• built-in rollback functionality

and their consequences;

• rock solid system even with relatively up to date packages
• possibility to enable automatic updates in background without fearing breakage
• (quasi) factory reset feature
• setting up a new system in just a fraction of the time required otherwise

are the primary reasons why I absolutely adore atomic/immutable distros.

Furthermore, it minimizes all kinds of issues related to or caused by bit rot, configuration drift and hidden/unknown states. (Note that you won't reap all of these benefits on all atomic/immutable distros.)

Honestly, IMO the end-user benefit is mostly that it sounds cool.

All the benefits I've heard (including the ones in this discussion) don't actually derive from "immutability" but from releases that stay the same for longer (which is what "more stable" used to mean), or the ability to roll back your system to some "known" working state (which you can do with snapshots and in a plethora of other ways).

What immutability means is that users are unable to alter their system, or at least not expected to... basically, it means what in corporate lingo would sound "altering your system is not supported" and that the distro actively makes it hard for you to do so.

This means users will not break their system because they followed badly some instructions they found on some badly written forum post anymore and blame the distro for it, but it also means that users who actually have a reason to alter their system and know what they are doing will have a hard time doing it (or be unable to), which is precisely why I left macos and went back to linux for my work computer some ten years ago (I spent half a day doing something I could have be done with in five minutes and said to myself "never again").

For the team/company that builds it, an immutable distro will likely be easier to test and maintain than a "regular" one, which should then indirectly benefit the users (well... as long as the team/company interests are aligned with the users' of course: shall windows get easier for microsoft to maintain, how much benefit would trickle down to its end users?).

Users who switch to an immutable distro should see a decrease in bugs short-term. In the longer run, I'd expect distros (especially the "commercial" ones) to reduce the effort they spend in QA until quality drops again to whatever level is deemed appropriate (if bread costs less I'm still not gonna buy more bread than I need... same goes for quality).

Basically, it all boils down to "immutable distros cost less to maintain" (which, don't get me wrong, is a net positive).

I must say I find it slightly concerning to have heard several "veteran" linux users say that immutable distros are so great that they will install one on their parent/child/SO/friend's PC but on their own.

It's also a bit unnerving to notice that most of the push for immutability seems to come from companies (the likes of debian/arch/gentoo/etc. are not pushing for immutability AFAIK, and they certainly don't have the initiative in this field).

I'm not sure how much immutable distros will benefit the community at large, and... I'm not even sure they will end up being very successful (windows/macos follow in whatever makes is more profitable for microsoft/apple, linux users have choice).

I hope that immutable distros will prove both successful and good for the user community at large.

edit: Forgot to explain the positives I hope for: since immutable distros should require less effort, I hope this will lead to more/better "niche" distros from small teams, and to distros with bigger teams doing more cool stuff with the extra manpower

I could see it being useful for like an office or something, where you do a big roll-out to a bunch of people. I'd assume having the system files be read-only and (presumably) the same on every system would eliminate a lot of guesswork for IT troubleshooting.

Essentially: read-only system files.

In immutable distros, you or any other programs that are installed on the system cannot modify the system files. That includes the system configuration files as well as applications. Its goal is to solve the problem of an entity gaining admin privlieges to your system and cause loads of damage. There are some addtional benefits too:

• Updates apply at reboot
• Root partition is read-only
• Considered very secure
• Sandboxed applications via flatpaks, snaps and appimages.

Have actually tried it! And while I love the concept and how it works, its a bit too much to learn for me at the moment. It's defo something I am going to pick up again in the future though! Also amazed me exactly how many more packages it had available than the AUR, mind blowing.

Thanks for insight!

You don’t have to install everything as a flatpak if you don’t want to. You can totally install most things in a rootless distrobox container, then use distrobox export (if you’re using distrobox instead of toolbx) to get a nice desktop entry. It’s how I run VSCode and Quartus Prime, for example.

Its honestly not that bad installing apps on these distros. Yeah the main one is flatpak, secondly appimages as easy as ever, and any other app can be installed via distrobox and exported if needed. If not that, then apps can also be layered onto the system if needed.

Ultimately it boils down to user preferences, but considering the growth and popularity of Immutable versions of distros, I would be surprised to not see a few more attempts from the Arch side of Linux.
