When restoring into a different cgroup with
--manage-cgroups-mode=ignore, the process is placed in the configured cgroup but its private cgroup namespace is not preserved./proc/self/cgroupconsequently exposes the host-relative cgroup path instead of0::/.This change keeps the restored process in a private cgroup namespace. The existing test for restoring into a new cgroup now checks that
/proc/self/cgroupstill reports0::/after restore.Fixes #5417
