.Dt RC.SHUTDOWN 8
.Os
.Sh NAME
.Nm rc.shutdown
.Nd command script run at system shutdown
.Sh SYNOPSIS
.Nm /etc/rc.shutdown
.Sh DESCRIPTION
When the system is shut down using the
.Xr reboot 8
or
.Xr halt 8
commands,
or when
.Xr init 8
is signalled to do so,
or when a keyboard-requested halt is issued (if the architecture supports it),
.Xr rc 8
is invoked with the argument
.Dq shutdown .
This document details the actions taken by
.Xr rc 8
in such an instance.
.Pp
Firstly it saves random data for reseeding the kernel random number
generator during the next boot.
It then stops any daemons
defined in the
.Va pkg_scripts
variable in
.Xr rc.conf.local 8 ,
by passing them the
.Cm stop
argument.
.Pp
.Xr rc 8
then runs
.Nm .
The administrator should place in this file
any commands they wish to have executed during shutdown.
.Pp
Finally, all
.Xr carp 4
interfaces are brought down and then the system shuts down.
.Pp
If
.Xr init 8
is exiting single-user mode it will also run the first part of shutdown
(saving random data),
though not the latter.
