+Subject: mount should set proper permissions on locktime
+
+When creating the "/etc/mtab~" lockfile (specifically 'linktargetfile'  in the
+lock_mtab function), the file is created with incorrect permissions ('000')
+which necessitates root to leverage CAP_DAC_OVERRIDE. If proper file modes (it
+would appear 0600 would be sufficient) were used in the open this would
+function properly with CAP_DAC_OVERRIDE revoked.
