reboot(1M)                     DG/UX R4.11MU05                    reboot(1M)


NAME
       reboot - restart the operating system

SYNOPSIS
       /sbin/reboot [ -lnq ] [ boot-path ]

DESCRIPTION
       Reboot restarts the kernel.  The kernel is loaded into memory by the
       PROM monitor, which transfers control to it.

       Although reboot can be run by the privileged user at any time,
       shutdown(1M) is normally used first to warn all users logged in of
       the impending loss of service.  See shutdown(1M) for details.

       The reboot command performs a sync(1) operation on the disks, and
       then a multiuser reboot is initiated.  See init(1M) for details.

       Reboot normally logs the reboot to the system log server,
       syslogd(1M), and places a shutdown record in the login accounting
       file /etc/wtmp.  These actions are inhibited if the -l, -n, or -q
       options are present.

       The following options are available:

       -l     Do not log the system shutdown to syslogd.

       -n     Do not sync the disks before halting (see sync(1M)).  This is
              a dangerous option because data in system buffers may be lost.

       -q     Quick.  Reboots quickly and ungracefully, without first
              shutting down running processes.

       boot-path
              Use the specified boot-path when rebooting.  If the boot-path
              is not specified, the current boot path is used.  By default,
              this is the boot path used when the system was last booted.
              The current boot path can be changed with the dg_sysctl(1M)
              command.  For Intel machines, the primary default boot command
              string, boot_command_1, can be set by the admnvram(1M)
              command.  On m88k machines, the default boot command string(s)
              can only be set from the SCM (System Control Monitor).

   Power Fail and Crash Recovery
       Normally, the system will reboot itself at power-up or after crashes.
