reboot(8)						      System Manager's Manual							 reboot(8)

Name
       reboot - automatic reboot procedures

Syntax
       /etc/reboot [ -n ] [ -q ]

Description
       The  ULTRIX  system is booted by loading a kernel image, usually into memory at location zero and transferring to zero.	Because the system
       is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.

       When the reboot of a running system is desired, is normally used.  If there are no users, can be used.  The command causes the disks to	be
       synced,	and  then  a multiuser reboot is initiated.  The system is booted and an automatic disk check is performed.  If the procedure suc-
       ceeds, the system is then brought up for the users.

       The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system.  A consistency check
       of the file systems will be performed and, unless the check fails, the system will resume multiuser operations.

Options
       -n   Prevents the disks from being synced.

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

Files
       System code

reboot(2)							System Calls Manual							 reboot(2)

Name
       reboot - reboot system or halt processor

Syntax
       #include <sys/reboot.h>

       reboot(howto)
       int howto;

Arguments
       howto   The howto argument is a mask of options passed to the bootstrap program.

	       The bits of howto are:

	       RB_HALT
		      the processor is simply halted; no reboot takes place.  RB_HALT should be used with caution.

	       RB_ASKNAME
		      Interpreted  by  the bootstrap program itself, causing it to inquire as to what file should be booted.  Normally, the system
		      is booted from the file "xx(0,0)vmunix" without asking.

	       RB_SINGLE
		      Normally, the reboot procedure involves an automatic disk consistency check and then multi-user operations.  RB_SINGLE  pre-
		      vents  the consistency check, rather simply booting the system with a single-user shell on the console.  RB_SINGLE is inter-
		      preted by the init(8) program in the newly booted system.  This switch is not available from the system call interface.

	       Only the superuser may a machine.

Description
       The system call reboots the system, and is invoked automatically in the event of unrecoverable system failures.	The system call  interface
       permits	only  RB_HALT or RB_AUTOBOOT to be passed to the reboot program; the other flags are used in scripts stored on the console storage
       media or used in manual bootstrap procedures.  When none of these options (for example, RB_AUTOBOOT) is given, the system is rebooted  from
       file in the root file system of unit 0 of a disk chosen in a processor-specific way.  Normally, an automatic consistency check of the disks
       is then performed.

Return Values
       If successful, this call never returns.	Otherwise, a -1 is returned, and an error is stored in the global variable errno.

Diagnostics
       The call fails under the following condition:

       [EPERM]	      The caller is not the superuser.
