bOS

These are my personal Universal Blue image builds, customized with a few extras to make life good on my family's laptops and home servers.

The name is intentionally ambiguous and fun. Is it "boss", or "bee-O-S", or "bee-aws"?

Under the Hood

There's a single image name bos with multiple tags. The idea is, I run bOS for all my use cases.

Desktop(and laptop) images are built upon Bluefin.

bos:bluefin - a Bluefin stable image with ZFS support
bos:bluefin-nvidia - a Bluefin stable image with ZFS and Nvidia support
bos:bluefin-dx - a Bluefin stable image with ZFS support with extra developer features
bos:bluefin-dx-nvidia - a Bluefin stable image with ZFS and Nvidia support with extra developer features

Server images are built upon uCore.

Use the installation method for the respective upstream, Bluefin, uCore, etc.

Then switch to bOS with a command like:

sudo bootc switch --enforce-container-sigpolicy ghcr.io/bsherman/bos:TAG

These images are signed with sigstore's cosign using. You can verify the signature by running the following command:

cosign verify --key cosign.pub ghcr.io/bsherman/IMAGE_NAME:TAG

This repo was built on the Universal Blue Image Template though it's been added to significantly.

That template can be used to extend any image you like, Aurora, Bazzite, Bluefin, uCore or even bOS so you can make your own bOS!

Also, if you just want to tinker, the images built here can be built locally using just and the provided Justfile.
