Atomic desktops enforce immutability, the core system is literally a ROM almost like stock Android.
Thank you for quenching my curiosity! The analogy to Android makes me worry that you might be associating stuff with atomic distros that are not (inherently) tied to them. Which, to be fair, happens a LOT, unfortunately…
secureblue imposes slightly less restrictions.
In short, as secureblue is ultimately derived from Fedora Atomic, it follows (most of) its conventions. Though, it’s most similar to uBlue in particular due to relying on their images initially. As such, all methods of installing software on say Bazzite apply to secureblue as well. Note, however, that secureblue prefers to keep it leaner for the sake of both security and simplicity. Finally, like Fedora Atomic and uBlue, it also allows you to customize the guts of your OS by creating/configuring an image.
However, AFAIK it is not lightweight enough for my setup. Pretty same as Gentoo, I guess.
If you can run KDE Plasma, then you should be able to run both NixOS and Gentoo.
my learning curve will be fairly steep

😅. Honestly, I think it’s exaggerated. But I’m only ankles deep in NixOS…




Probably yeah.
I don’t know if that’s the case. Immolo, AKA the Gentoo guy on YT, tried compiling Firefox for speed. But the results weren’t what you’d expect. Granted, efficiency =/= speed. So YMMV.
That is plenty. Sure, it’s not comfortable or anything. But it’s fine for strictly running your OS without delving into stuff like VMs, high-end gaming etc. Perhaps you might even pick/prefer tools/software that are known to be less bloat~y.
So, if what you desire is simply “Do what I want as fast as possible.”, then I agree that compiling is a no-go. But, the control gained on Gentoo by virtue of the extensive options that are provided through compilation is no joke.
Hence, I got to ask, what is it that you ultimately desire?
Btw, FWIW, if speed and/or efficiency is more important than control. And, if control is (mostly) only desired to benefit speed and/or efficiency, then perhaps the likes of Alpine and Void should also be considered for the long-term.
