I think we should replace this whole EESSI block with running the configure task directly. But it is not obvious how to do this TBF ...

I've tried to describe it in https://wiki.stackhpc.com/doc/slurm-development-ZXjBRByl6K#h-only-inventory-vars
so you could change the entire eeesi thing to do this.

I'm not sure whether there is always a /dev/nvidia0? Could you check with @jovial please for e.g MIG and vGPU configs? Else we'd have to do something like https://github.com/stackhpc/ansible-role-openhpc/blob/be6196540ca8007a0e45f2c3b2596ed0ff77fc13/library/gpu_info.py#L42 but TBH this approach here is much simpler!

Strictly, this is checking for the device, which is only present if the driver is loaded. So I suggest:
| - name: Check for NVIDIA driver | |
| - name: Check for NVIDIA GPU |
| path: /dev/nvidia0 | ||
| register: nvidia_driver | ||

…pliance into configure-gpus Apply changes to task names
Add tasks to
eessi/configure.ymlandcompute-init.ymlto run the EESSIlink_nvidia_host_libraries.shscript on gpu nodes with nvidia drivers installed. The tasks will be run when eithersite.ymlis run or a rebuild via slurm is completed.
