Subject: [PATCH 9/9] mount: use standard mountpath if path is ommitted
Date: Sun, 29 Sep 2013 12:05:00 +0200	[thread overview]
Message-ID: <1380449100-6295-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1380449100-6295-1-git-send-email-s.hauer@pengutronix.de>

With this a mount <devname> will mount the device to /mnt/<devname>. This
directory is created automatically if it doesn't exist already.
