The motivation for this is to be able to restore containers into cgroups other than what they were dumped in (if, e.g. they might conflict with an existing container). Suppose you have a container in: memory:/mycontainer cpuacct,cpu:/mycontainer blkio:/mycontainer name=systemd:/mycontainer You could then restore them to /mycontainer2 via --cgroup-root /mycontainer2. If you want to restore different controllers to different paths, you can provide multiple arguments, for example, passing: --cgroup-root /mycontainer2 --cgroup-root cpuacct,cpu:/specialcpu \ --cgroup-root name=systemd:/specialsystemd Would result in things being restored to: memory:/mycontainer2 cpuacct,cpu:/specialcpu blkio:/mycontainer2 name=systemd:/specialsystemd i.e. a --cgroup-root without a controller prefix specifies the new default root for all cgroups.
