Subject: [ptxdist] [PATCH v2] udev: fix error on kernels without uevent helpers
Date: Tue, 23 Jun 2015 16:36:02 +0200 [thread overview]
Message-ID: <1435070162-6890-1-git-send-email-clemens.gruber@pqgruber.com> (raw)
Current kernel docs recommend disabling CONFIG_UEVENT_HELPER.
If disabled however, the following error message is shown:
/etc/rc.d/S00udev: line 95: can't create /proc/sys/kernel/hotplug:
nonexistent directory
This patch fixes it by checking if /sys/kernel/uevent_helper exists.
