Question Text​

Who is the parent of the sleep processes? Why?

Question Answers​

  • sleepy_creator.py because it is the one who created them

  • bash because it is sleepy_creator.py's parent and when a process dies, its parent adopts its orphan children

  • systemd because this is the default process that adopts orphans
  • systemd because it is sleepy_creator.py's parent and when a process dies, its parent adopts its orphan children

When a process dies without waiting for the termination of all its children, those processes are now orphans. Then the systemd process adopts those orphan processes by default. On older Linux systems, it was the init process who adopted orphans.
