Subject: bug#15356: [PATCH 13/19] libparted: Add Intel Rapid Start Technology partition flag.

From: "Brian C. Lane" <[email-masked]>
Date: Wed, 11 Sep 2013 12:25:03 -0700

From: "Brian C. Lane" <[email-masked]>

This adds support for the irst partition type flag. Sets the type to
0x84 on MS-DOS and D3BFE2DE-3DAF-11DF-BA-40-E3A556D89593 on GPT.

 ** Changes in behavior
 
+  Added new partition type flag, irst, for use with Intel Rapid Start
+  Technology. On MS-DOS disk labels it sets the type to 0x84 and on GPT
+  it sets the GUID to D3BFE2DE-3DAF-11DF-BA-40-E3A556D89593.
+
   parted -l no longer lists device-mapper devices other than
   dmraid whole disks.
