Document Summary

Is currently the default initialization process used in the fedora, centos, and red. Hat linux distributions: uses units and targets instead of shell scripts and runlevels. The systemd method: units and targets: a unit defines a service or action on the system. It consists of a name, a type, and a configuration file: types of systemd units automount, device mount path service snapshot, socket target, the systemd program identifies units by their name and type using the format name. type. Each target represents a different group of services that should be running on the system. Instead of changing runlevels to alter what"s running on the system, you just change targets: there are targets that mimic the standard 0 through 6 sysv runlevels, called runlevel0. target through runlevel6. target. The systemd method: configuring units: each unit requires a configuration file that defines what program it starts and how it should start the program.
