Description of problem:

Containerfile.cuda uses ENV. ENV in bootc does not work. The env variables are not available in the host system, https://bootc-dev.github.io/bootc//building/bootc-runtime.html#env-oci-env .

I suggest that you remove "ENV" and add a linter that blocks any use of ENV in bootc images.

If you need the env variables to persist, then you have to add them through other means, e.g. systemd configuration.
