From 94e2a0cd63935708815bfaa3399fb57210d94065 Mon Sep 17 00:00:00 2001 From: Adrian Reber Date: Tue, 25 Jun 2019 12:22:33 +0000 Subject: Track if a container is restored from an exported checkpoint Instead of only tracking that a container is restored from a checkpoint locally in runtime_ctr.go this adds a flag to the Container structure. Upcoming patches to correctly label the root file-system mount-point need also to know if a container is restored from a checkpoint. Instead of passing a parameter around a lot of functions, this adds that information to the Container structure.
