From 5e43c7cde1da185f3a9dc4f949e778b087d4ea42 Mon Sep 17 00:00:00 2001 From: Adrian Reber Date: Thu, 28 Nov 2019 19:04:35 +0000 Subject: Disable checkpointing of containers started with --rm Trying to checkpoint a container started with --rm works, but it makes no sense as the container, including the checkpoint, will be deleted after writing the checkpoint. This commit inhibits checkpointing containers started with '--rm' unless '--export' is used. If the checkpoint is exported it can easily be restored from the exported checkpoint, even if '--rm' is used. To restore a container from a checkpoint it is even necessary to manually run 'podman rm' if the container is not started with '--rm'.
