Comment # 24 on bug 1211796 from Michal Koutný

I have
kmod-30-4.1.x86_64
and kernel build is broken:

> make O="$BUILD_DIR_C" INSTALL_MOD_PATH="$BUILD_DIR_C/mods" modules_install

scripts/depmod.sh effectively calls 'depmod -b $INSTALL_MOD_PATH'
but `make modules_instdall` won't install under usr/ prefix.

Perhaps usr-lib-modules.patch should drop the hunk:

--- a/tools/depmod.c
+++ b/tools/depmod.c

        }

        cfg.dirnamelen = snprintf(cfg.dirname, PATH_MAX,
-                                 "%s/lib/modules/%s",
+                                 "%s" PREFIX "/lib/modules/%s",
                                  root == NULL ? "" : root, cfg.kversion);

        if (optind == argc)

IOW take value of `-b` arg verbatim regardless of configured prefix.
