From 9968e376a17dd6d815473f05843b1f257b2babd5 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 1 Oct 2008 18:50:43 -0700 Subject: [PATCH] fname_as_uuid: print uuids msb first The sha1 routines store the uuids in little endian byte-order, so always print from msb to lsb. This allows imsm containers to be assembled with -As.
