@laraPPr Ignore the failing CI check for now, I'm trying to fix that in #9 ...

[ocaisa]

A sync with main is probably a good idea here

I think you can have a couple of tests for this, there's mocking for nvidia-smi in https://github.com/laraPPr/software-layer-scripts/blob/utils_function_nvidia/.github/workflows/tests_link_nvidia_host_libraries.yml#L37 . You could add the test there.

This is now exactly mimicking the behavior but I'm not sure this is correct.
This is now set in this case No 'nvidia-smi' found, no available GPU but allowing overriding this check.

[laraPPr]

It is indeed now always set. I do not think this is what we want, right. exerpt of logs from EESSI/software-layer#1143

No 'nvidia-smi' found, no available GPU but allowing overriding this check

In our scripts this is fine, it is a once only thing, once things are installed they are not reinstalled.

This looks good, a CI check would be great. You can do it in https://github.com/EESSI/software-layer-scripts/blob/main/.github/workflows/tests_link_nvidia_host_libraries.yml, check once before nvidia-smi is mocked that it returns non-zero, and once after it has been mocked

Implemented the CI see https://github.com/EESSI/software-layer-scripts/actions/runs/16718197861/job/47316223515?pr=22 and I think it does what is expected?

[ocaisa]

This looks good, can you sync it with main, I think the broken CI should have already been fixed there since Friday

LGTM, thanks @laraPPr
