bazzite

"Bazzite is a custom Fedora Atomic image built with cloud native technology that brings the best of Linux gaming to all of your devices - including your favorite handheld." - https://bazzite.gg

Notes

Based on https://universal-blue.org, "The Universal Blue project builds a diverse set of continuously delivered operating system images using bootc. That's nerdspeak for the ultimate Linux client: the reliability of a Chromebook, but with the flexibility and power of a traditional Linux desktop." The base OS is an OCI image, and any customizations that happen to the OS are done in the local filesystem that is layered on top of the base OS.

Notable, the base OS images are only hosted for 90 days, after which they are deleted.

OS operations are done through a custom just script called ujust which is just a just wrapper pointing to a specific configuration.

Network configuration is done through nmcli

Examples
