ucore VS main

uCore does this if you wanna check it out: https://github.com/ublue-os/ucore

Flatcar uses 2 partitions, A and B, you boot into one and then updates update the one that you're not booted into, when you reboot it it boots into the updated one. It's like Android: https://source.android.com/docs/core/ota/ab

I maintain an awesome-list of immutable resources here with a collection of talks and presentations from the people making the stuff: https://github.com/castrojo/awesome-immutable

However I'm currently focused on desktop stuff since the it's a fairly common pattern in cloud already, I should probably write it up.

Semi-related, a few of us have started a community around composable OCI fedora images, and one of our images is intended to be used as a home server built on CoreOS with ZFS, cockpit, and all the goodies you'd need. It's still fresh and we're looking for help if anyone's interested: https://github.com/ublue-os/ucore (Disclaimer: I helped start this project)

Best place to start is to get rid of all the layered packages (RPMFusion) on top of the immutable image then swap to the ublue-Nvidia images that have all the codecs and Nvidia drivers built into the image itself.

If you're using Nvidia I'd recommend using Fedora Kinoite with the ublue-Nvidia image that comes with the Nvidia drivers pre-built in. That eliminates a big chunk of issues with their drivers which is just building the damn things. AMD and Intel drivers are built into the kernel and require zero effort.

What you are looking for is UBlue, https://github.com/ublue-os/main.

It's a variant of Silverblue with Nvidia drivers built in.

If you're using Nvidia, then install using the ublue Nvidia image which has the drivers built in, cause they can be a prick to manage otherwise.

What these sort of introductions to immutable always fail to consider is the other side of the coin, image-based. I'm working on https://universal-blue.org/ along with many people much more skilled than me. We build OCI container images on top of vanilla Fedora Silverblue & many other editions with different desktops. Those images can then be booted to (or rather rebased to) using rpm-ostree. This is a more robust way of extending the system than layering, and the same changes can be easily benefited or inherited from by anyone. You can even make your own image really easily!

I think that VanillaOS and SUSE are working on similar things, but we're not an OS project, just a downstream from Fedora. Fedora's full support is underway but with what's already working perfectly our methods are already IME some of the most robust and easy ways of delivering Nvidia drivers for example.
