          Priority: medium
            Bug ID: 68370
          Assignee: systemd-bugs at lists.freedesktop.org
           Summary: systemd-nspawn -b doesn't cleanup machine slice if
                    systemd inside container
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: maxposedon at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

systemd-nspawn doesn't clean all machine slices, so restarting doesn't work
(see below). After removing slice in /sys/fs/cgroup, it starts fine.
