From f7b8445f2e89ad0a59c2859f9eb26855769f1070 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 24 Oct 2014 17:39:40 +0200 Subject: udev: fix uevent-helper disable Make sure that /proc/sys/kernel/hotplug exists before trying to disable the uevent-helper mechanism. Since kernel commit 86d56134f1b6 ("kobject: Make support for uevent_helper optional.") the kernel can be built without uevent-helper support. In this case /proc/sys/kernel/hotplug does not exist and the current sysvinit script fails with /etc/rcS.d/S04udev: line 132: can't create /proc/sys/kernel/hotplug: nonexistent directory when trying to disable the uevent-helper mechanism during boot. Note that a single NULL-character has always been sufficient to disable.
