Re: You missed the point
I looked for approximately the same type of OS for the same reason - something that could be installed onto laptops not supported by Win 11. In my car as a volunteer or a repair/reuse charity, looking towards the end of 10.
The best I could find was Fedora Silverblue, as I was looking for an environment where a minimal environment was provided which could be extended with Flatpak or similar via some GUI marketplace. Silverblue ticked almost all the boxes I had, though the one thing that was missing when I looked was some form of "factory reset" which could be performed from the UI.
I suspect this is isn't really a feature Fedora's team see as a high priority - the OS isn't typically pre-installed and the presumption is probably that the person installing the OS will be around to reinstall should it be required at a later date. This however was exactly the thing I was trying to avoid needing...
I kinda feel that it's this point - the expectation of a fairly tech literate person being on hand post install - that's leading to this use case being under served.
