You didn’t! :) You couldn’t have said it better, especially in your answer here!
As I said, I had the same thought as you with immutable distros like SB or Nix.
I just didn’t have much to add as an additional comment besides “Kids, this why you should always backup and maybe use an immutable distro if you can”.
As someone who values robustness and comfort, I wouldn’t touch something arch-based even with a broom-pole.
If I wanted something that’s a rolling release, I would use Tumbleweed or it’s immutable variant.
For me at least, the only pro in Arch is that you can configure everything exactly to your imagination, if I know exactly what I’m doing. And EndeavorOS is pretty much a pre-configured Arch that removes the only USP of it, the DIY-element.
I don’t see myself as competent enough to maintain my arch install, but I can access the AUR with distrobox on every other distro, like Silverblue, too, so I don’t care. The big software repository isn’t an argument for me in 2023 anymore. With distrobox my arch stuff is isolated and if something breaks, I can just forget my two installed apps and reinstall this container in 2 minutes.
It’s just an unimaginable peace of mind for me to know that if I shut down my PC today it will work perfectly tomorrow too. I’m just sick of reinstalling or fixing shit for hours every weekend. I’m too tired for that and have other responsibilities.
But yeah. My thoughts were exactly the same as yours and I didn’t have much more to add besides saying “Hey, do xy that this won’t happen anymore in the future” without sounding like Captain Hindsight from South Park. Context
