How does rocm-arch deal with library paths (ld.so.conf, LD_LIBRARY_PATH)

I will admit I haven't installed rocm-arch on my PC yet. The reason is mostly that I'm maintaining a binary package for ROCm based on the Ubuntu release, and it would take a lot of effort and resources to uninstall / install all the time.

I'm trying to understand what is the correct way to provide the library paths to software like Pytorch / Tensorflow / JuliaGPU etc. I thought adding the paths to ld.so.conf would be enough but it doesn't seem to be working. Only when I set the LD_LIBRARY_PATH these applications start to work properly. So my question is what I'm doing wrong and how does rocm-arch deals with it?

My assumption after a lot of investigation and trial and error is that the RUNPATH of the executables messes with this, because the search priority for runpath is higher in the linker order. So ld.so.conf should work fine as long as the executables are not pointing to a wrong library path.

This is how we do it in the PKGBUILDs.
