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. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Ross Burton <ross.burton@intel.com>
