I have opensuse tumbleweed with kernel 6.4.3-1-default installed.

I have this repo activated:
https://developer.download.nvidia.com/compute/cuda/repos/opensuse15/

And installed this rpm:
https://developer.download.nvidia.com/compute/cuda/repos/opensuse15/x86_64/nvidia-gfxG05-kmp-default-535.104.05_k4.12.14_lp150.12.82-0.x86_64.rpm

After reboot, I ended up without nvidia-driver running.

Investigating: I found, that kernel-module was compiled, but installed (hardcoded) to
/lib/modules/4.12.14-lp150.12.82-default/updates/
which is the wrong location

Running
rpm -qi --scripts  nvidia-gfxG05-kmp-default
shows me following postinstall scriptlet:

When I replaced the hardcoded "4.12.14-lp150.12.82" with my kernel version and run the script again, I have the new driver running after reboot! The install-location should not be hardcoded.
