Ah great thanks for the pointers :)
Please keep in mind that any image based on top of the aforementioned distributions will fail to run on the cluster (due to the clone3 syscall invoked whenever a child process is created), even if pre-built and pushed to a different registry.
Hmm, that might be a problem. I will look into it anyways since I think we should have our image being build-tested at least
Thanks for your help!
