Impact

The ceph-crash.service runs the ceph-crash Python script as root. The script is operating in the directory /var/lib/ceph/crash which is controlled by the unprivileged ceph user (ceph:ceph mode 0750). The script periodically scans for new crash directories and forwards the content via `ceph crash post`.

There is no known workaround at this time.
