From 92fd453c6717acbeafcbbac39084a6f1c9ac6827 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Mon, 29 Jul 2019 17:29:02 +0100 Subject: [PATCH] Revert "Revert "globals: Allow global properties to be optional"" This reverts commit 8fa70dbd8bb478d9483c1da3e9976a2d86b3f9a0. Because we're about to revert it's neighbour and thus uses an optional again. Signed-off-by: Dr. David Alan Gilbert Message-Id: <20190729162903.4489-2-dgilbert@redhat.com> Reviewed-by: Michael S.
