I have a need for an extremely locked down desktop environment that would have three profiles
School - Can only run Libreoffice and Firefox. When I say ONLY I mean ONLY - can't change any setting at all, not even the desktop wallpaper. The ability to not even see settings would be ideal as well. This would be kind of like a kiosk profile where the desktop has shortcuts to run the two programs and that's it.
Games - Similar to School profile in that no settings can be changed but I could somehow put apps on the desktop a needed (i.e. - Minecraft)
Administrator/root - Can do anything, normal desktop experience
I looked around at kiosk desktop experiences but they seem to just limit a user to only one application, not the ability to switch between two or more. Additionally I looked at kids distro's but they are seemingly just a streamlined desktop experience (no menus - which I like), but you still have the ability to edit user settings and whatnot.
Is there even a distro like this or something that could be customized to do this without a ton of work? I know what I'm asking for is not normal
