ublue-os/main

AI Summary: Investigate and potentially implement the greenboot Rust rewrite (https://github.com/fedora-iot/greenboot-rs) into the uBlue OS Fedora base images. This involves testing the greenboot implementation and assessing its compatibility with the existing uBlue build process and images (Aurora, Bazzite, Bluefin). Given the project's deprecation notice, focus should be on base, kinoite, and silverblue images.

AI Summary: Investigate and potentially implement a generalized GitHub Actions workflow across all uBlue OS images to mount storage instead of using `remove-unwanted-software`. This aims to reduce build times by approximately 3 minutes per build, as demonstrated in the linked pull request for the Bazzite-dx image.
