File usr-lib-modules.patch of Package kmod
From 9d1fb317c8dbf2b834b3d0efb34208eb8fb790fb Mon Sep 17 00:00:00 2001 From: Michal Suchanek <msuchanek@suse.de> Date: Fri, 10 Nov 2023 13:13:54 +0100 Subject: [PATCH 7/9] libkmod, depmod, modprobe: Make directory for kernel modules configurable Now that modprobe.d is searched under ${prefix}/lib, allow a complete transition to files only under ${prefix} by adding a ${module_directory} configuration. This specifies the directory where to search for kernel modules and should match the location where the kernel/distro installs them. With this distributions that do not want to ship files in /lib can also move kernel modules to /usr while others can keep them in /lib.
