From 0c7e8d1317daa86da7d1cfdea7733f8091a002c1 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 26 Jan 2015 09:44:18 -0600 Subject: gpt: support random UUIDs without setting environment variables Currently, an environment variable must be used to store the randomly generated UUID for each partition. This is not necessary, so make storing the UUID optional. Now passing uuid_disk and uuid are optional when random UUIDs are enabled.
