Ubuntu: 3 processes that couldn't have had init as an initial parent



Question:

Name 3 processes that couldn't have had init as an initial parent can any one help me on parent which doesn't have children in Ubuntu this question refers to Linux handbook


Solution:1

Some kernel processes are started before init, but have a PID ≥ 2. These processes have no parent. And the children of these processes also don't have init as an ancestor.

To see them, try pstree 0.
