An atomic distro is one which is in my understanding, has a basis in libostree, right? I’m familiar with the Fedora/RedHat versions but not any others.
Immutable distributions, for me to are wonderful when they are sparse. I don’t want anything on my OS which I don’t use at least once on a while.
If I install Fedora (RPM) Workstation to a large extent I can remove programs that I don’t want. Whereas SilverBlue (libostree), I’m stuck with whatever the maintainers template (is there a blocking mechanism?).
However, with sparse Fedora-IoT, I can’t break it - to a large extent - and it doesn’t have anything I don’t want.
I always install minimal versions of OSs, from Fedora (Everything iso), to Debian (debootstrap) to ArchLinux to Exherbo to Talos, just keep them cleaner longer. Then I fix them until they break!
I think they’re ideal for those starting out in Linux because they are not ready to break; not saying that they’re not for others too.
There’s enough documentation, at least for Fedora atomic distros, to make your own custom spin.
I’m not switching for any desktop, unless the basic OS is minimal; but have switched for Raspberry Pi OS to Fedora IoT (atomic distro), at least temporarily.
Install your own from one of the parent distros: Debian, Fedora/openSUSE, sources (eg. Exherbo, Gentoo), the state-based one I always forget.
