Subject: [PATCH kmod v2 4/4] libkmod, depmod, modprobe: Search for kernel modules under ${module_prefix}
modprobe.d is now searched under ${prefix}/lib, add ${module_prefix} to
specify the directory where to search for kernel modules.
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.
