From 8fc62e59425389a6d48429b9d146223122743435 Mon Sep 17 00:00:00 2001 From: Michal Marek Date: Tue, 12 Jul 2011 11:54:48 +0200 Subject: kbuild: Do not write to builddir in modules_install Let depmod.sh create a temporary directory in /tmp instead of writing to the build directory as root. The mktemp utility should be available on any recent system (and there is already scripts/gen_initramfs_list.sh relying on it).
