LWN has had a number of articles on immutable distributions, such as Bluefin and Bazzite, in recent years. These distributions have taken a variety of approaches, including using rpm-ostree, filesystem snapshots, and bootable container (bootc) images. But those approaches, especially the latter, lead to extra complexity for a user attempting to install new software, instead of just using the existing package manager. AshOS (Any Snapshot Hierarchical OS) is an experimental AGPL-3-licensed “meta-distribution” that tried a different approach more in line with traditional package management. Although the project is no longer updated, it remains usable, and can still shed some light on a potential alternate path for users worried about adopting bootc-based approaches.
