systemd is the first daemon to start during booting and the last daemon to terminate during shutdown. The systemd daemon serves as the root of the user space's process tree; the first process (PID 1) has a special role on Unix systems, as it replaces the parent of a process when the original parent terminates. Therefore, the first process is ...

chroot is an operation on Unix and Unix-like operating systems that changes the apparent root directory for the current running process and its children.A program that is run in such a modified environment cannot name (and therefore normally cannot access) files outside the designated directory tree.
Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and video game console emulators , are designed to also emulate (or "virtually imitate") different system architectures, thus allowing execution of software applications and operating systems ...
For the duration of an orchestration task, a process running the module communicates with the controlling machine with a JSON-based protocol via its standard input and output. [18] When Ansible is not managing a node, it does not consume resources on the node because no daemons are run or software installed.
