RC.SHUTDOWN(8)              System Manager's Manual             RC.SHUTDOWN(8)


NAME

     rc.shutdown - command script run at system shutdown


DESCRIPTION

     When the system is shut down using the reboot(8) or halt(8) commands, or
     when init(8) is signalled to do so, or when a keyboard-requested halt is
     issued (if the architecture supports it), rc(8) is invoked with the
     argument "shutdown".  This document details the actions taken by rc(8) in
     such an instance.

     Firstly it saves random data for reseeding the kernel random number
     generator during the next boot.  It then stops any daemons defined in the
     pkg_scripts variable in rc.conf.local(8), by passing them the stop
     argument.

     rc(8) then runs rc.shutdown.  The administrator should place in this file
     any commands they wish to have executed during shutdown.

     Finally, all carp(4) interfaces are brought down and then the system
     shuts down.

     If init(8) is exiting single-user mode it will also run the first part of
     shutdown (saving random data), though not the latter.


FILES
