Subject: [PATCH 5/5] login: explain PASSWORD_DEFAULT option
Date: Thu, 27 Aug 2015 17:26:14 +0200	[thread overview]
Message-ID: <1440689174-731-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1440689174-731-1-git-send-email-s.hauer@pengutronix.de>

This option looks like it takes the default password, but instead
it takes a filename of a file which contains the password encoded
with the selected password digest.
