Qbert VS silverblue-site

I'd recommend qbert rather than disabling the read-only filesystem. It survives updates and you can just turn it off if you want to.

But if you do, qbert will make it behave like a normal arch Linux so you can follow the tutorials on the internet.

This was recommended to me: https://github.com/XargonWan/Qbert

Also, I would advise you use Qbert or Junest to install it, instead of making the filesystem writable, because a SteamOS update will wipe all that data

To do that, you will either need to unlock the read-only part or use qbert to get the same effect in a way that can't break stuff.

for pacman on deck you can use qbert, which will let you leave the system read-only and lets you keep your files between updates. You can even put it into .bashrc so it runs automatically on boot.

Fedora; from its 'flagship' Workstation, to their glorious Spins and their Immutable Desktops

Fedora Silverblue - pretty well-known at this point, but it’s championing immutability

Couldn't have said it better!

An example of an installable immutable OS is Fedora Silverblue. Notably, you can change the "distro" flavor of Silverblue to try out KDE and then just flip back to Gnome. Each change is seen as an "update" that just moves you over to the new GUI. The article below explains a bit more.

I guess something like Fedora Silverblue might offer you something (to paraphrase) "stupid proof". For example, in this case the rpm-ostree rollback command would have been sufficient. Disclaimer: rpm-ostree builds images, therefore it's by necessity slower than apt. Futhermore, until this change is merged and deployed you'd have to reboot for the changes to apply. You might want to look into Distrobox as well, perhaps it can solve your problems without having to change your distro.

However, I'll add one more that I'm especially fond of. It's one of the most 'stable'\1]) Linux desktop systems\2]) without sacrificing access to the latest kernel-updates and packages. It comes bundled with everything\3]) necessary for productivity right out of the box and is built on top of the fundamentals laid by Fedora's Immutable Desktops. Allow me to introduce uBlue; I know that I'll undersell it regardless, so I recommend you to check the provided link instead.
