Subject: [PATCH 2/2] file capabilities: turn on by default
Date: Mon, 22 Sep 2008 13:49:01 -0500	[thread overview]
Message-ID: <20080922184901.GA3688@us.ibm.com> (raw)
In-Reply-To: <20080922184835.GA2826@us.ibm.com>


Now that file capabilities can be turned off at boot, go ahead
and compile them into the kernel by default by making
CONFIG_SECURITY_FILE_CAPABILITIES=y the default.

Note that the boot flag no_file_caps must be specified to turn
file capabilities off, as by default they are on.  So the
default behavior is in fact changed.
