Comment Process management in a consistent way (Score 4, Interesting) 928
OK I'll try this. Traditionally Init services were about starting processes. They didn't have capacities for keeping processes running. Which meant that for processes that need to be kept running and for which there was a real possibility of failure (most of them) the init had to start a process management system which then started the functional process. This has been the status for years. With systemd there is a process maintenance component standard in the init system. Which means that processes not only start but are capable of being kept in a stable state easily and automatically. Process management stops being something system admins work hard at and instead becomes something that happens out of the box.
