Subject: [PATCH v2 2/3] overlay: use SCRATCH_BASE_DIR instead of SCRATCH_DEV
Date: Fri, 27 Jan 2017 10:56:04 +0200	[thread overview]
Message-ID: <1485507365-29012-3-git-send-email-amir73il@gmail.com> (raw)
In-Reply-To: <1485507365-29012-1-git-send-email-amir73il@gmail.com>

Use the new canonical var SCRATCH_BASE_DIR to refer to overlay
base dir instead of the old 'fake' SCRATCH_DEV var.
