- boot – Generally the only services you should add to the boot runlevel are those which deal with the mounting of filesystems, set the initial state of attached peripherals and logging. Hotplugged services are added to the boot runlevel by the system. All services in the boot and sysinit runlevels are automatically included in all other runlevels except for those listed here.
- single – Stops all services except for those in the sysinit runlevel.
- reboot – Changes to the shutdown runlevel and then reboots the host.
- shutdown – Changes to the shutdown runlevel and then halts the host.
- default – Used if no runlevel is specified. (This is generally the runlevel you want to add services to.)
