From c826233ad08ee5a4b9943a05d4e73f3fb3281588 Mon Sep 17 00:00:00 2001 From: Kristian Amlie Date: Mon, 6 Feb 2017 17:16:47 +0100 Subject: selftest/wic: Add tests for --exclude-dir option. Based partially on an earlier patch by Maciej Borzecki. Note that because tools now reside in recipe specific sysroots, we need to import the path from bitbake and apply it during the test.
