No, I am using fedora silverblue which is point release. But there are rolling release immutable distros like opensuse aeon/kalpa im pretty sure. Basically the system files are read only and packages are “layered” onto the system image through transactional upgrades. Most of the packages you want to install should be in containers like flatpak (for gui) and distrobox (for terminal). This keeps the base system clean and small and doesn’t get “bloated” like other mutable OS’s.
If you want lightweight, void is pretty good. Not sure about nvidia though.
I feel like this ruins the aspect of an archive of information where users can go back through and find useful info similar to SO in a way. Maybe there will be a meta search engine for looking through all of the popular instances?
