> Bazzite is an OCI image that serves as an alternative operating system for the Steam Deck

I'm not quite following - this is a host OS that runs things in containers, or the OS inside a container?

Fedora's OSTree recently-ish started supporting using OCI containers as the content-addressed image backend in addition to their original git-like one:

https://coreos.github.io/rpm-ostree/container/ https://fedoraproject.org/wiki/Changes/OstreeNativeContainer...

Are OCI images content-addressed?

What does content-addressed mean?

The identifier for the content (image layers + manifest) is the hash of the content, and the has serves as an "address", the registry repo + tag is basically a pointer to a hash.

Thank you. Would other type of addressing be something like offset-based or address-based? Just trying to imagine different ways a file can be packed as I never gave it much thought.

I'm pretty sure it's just the difference between a file being named foo.tar.gz and (SHA-256 of the file).tar.gz[0] - the content and storage are the same, it's just that the canonical name is a hash of the contents rather than being arbitrary.

[0] ex. 1324cca9ed1d8267363ef6c835ca251bd810c21c49b2acc00e02d607c95ef9ad.tar.gz

Yes

The OS is delivered to you via a container (via the github registry), but can also run things in containers.

The OS itself is run on the bare metal.
