$ nvidia-ctk cdi list
INFO[0000] Found 0 CDI devices
Problem: I run nvidia-ctk generate and put nvidia.yml to the custom directory being as a non-privileged user.
I add env XDG_CONFIG_HOME to my home dir and create nvidia-container-runtime there, where I re-define config.toml with custom spec-dirs values.
And if I run nvidia-ctk config - I see that the configuration at least can be read fine from my custom config file.
So I put nvidia.yml to /app/home/podman/cdi.
And nvidia-ctk cdi list show nothing.
But it shows devices if I run with flag --spec-dir, so it defenitely should work.
I expect nvidia-ctk cdi list to show devices without additional flag as soon as in the config I redefine spec-dirs.
What else am I missing here?
