    At least on Linux, a process created via docker exec inside a running
    container shows up with a ppid of 0 in /proc/<pid>/status.

    A bit more specifical: A ppid 0 indicates a Linux process whose actual
    parent is in a different PID namespace. This is actually even documented
    in pid_namespaces(7).
