From c70657a6d1fc15ba60d4bb0fc197f4c70fa59cac Mon Sep 17 00:00:00 2001 From: Adrian Reber Date: Thu, 27 Jun 2019 08:24:35 +0000 Subject: Add tests for --ignore-rootfs checkpoint/restore option This adds three tests for the --ignore-rootfs option to verify that it works in all combination. 1. Not used at all 2. Only used during restore 3. Only used during checkpoint Signed-off-by: Adrian Reber --- test/e2e/checkpoint_test.go | 124 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 124 insertions(+) diff --git
