NAME

reboot − UNIX bootstrapping procedures

SYNOPSIS

/etc/reboot [ −n ] [ −q ]

DESCRIPTION

UNIX is started by placing it in memory at location 400 and transferring to 400.  Since the system is not reenterable, it is necessary to read it in from disk or tape each time it is to be bootstrapped. 

Rebooting a running system.  When a UNIX is running and a reboot is desired, shutdown(1M) is normally used. If there are no users then /etc/reboot can be used.  Reboot causes the disks to be synced, and then a reboot (as described below) is initiated. 

Options to reboot are:

−n option avoids the sync.  It can be used if a disk or the processor is on fire. 

−q reboots quickly and ungracefully, without shutting down running processes first.
