Immutable Variants & Persistence

[Jonathan Steffan <jonathansteffan@xxxxxxxxx>]

Hello,

During a recent IRC conversation the question of always booting Fedora fresh on hardware came up. We've got the Live variants which do this already and it's possible to directly write them to a local disk. Similar to booting from a USB stick, you could use the local hardware instead. However, it's not really a read-only boot. Booting from a locally copied Live environment still allows full access.

Is there a way to configure the immutable versions to have a similar RAM only overlay?

I'd imagine an immutable base that is automatically updated and has all other runtime changes discarded on reboot. There could be an automatically logged in user that has extremely limited privileges and can only work in the current boot userspace.

Previously this has been discussed as something like a kiosk mode, but I could see this used in many other situations.

Thanks for any consideration,
