The following procedures are provided in this section:
Normally, the system reboots at power-up or after a system crash. You can reboot a system by using either the init command or the reboot command. The init 6 command asks for stop methods (either SMF or rc.d). Whereas, the reboot command does not, thereby making the reboot command a more reliable way of rebooting a system. See init(1M) and reboot(1M) for details.
The reboot performs the following actions:
Restarts the kernel
Performs a sync operation on the disks
Initiates a multi-user boot.
Although the reboot command can be used by the root user at any time, in certain cases, as with the reboot of a system with multiple users, the shutdown command is used first to warn all users who are logged in to the system of the impending loss of service. For more information, see Shutting Down a System.
