From their GitHub:
cpak installs applications from OCI images while keeping package metadata in a Git repository. It provides native desktop integration, shared content-addressed layers, atomic updates and a rootless Linux sandbox from one Go binary.
It seems interesting. I’ve never heard of it before, but apparently Bottles packages with cpak along with flatpak. The main reason I use flatpaks are its sandboxing capabilities, so it would be cool if cpak brings new stuff to the table while matching or overpassing the sandboxing capabilities.


Honestly, if any distro included this, it would be an instant red flag.
