Sd(4)                                                          Sd(4)


       NAME
             Sd - kernel module system shutdown script

       SYNOPSIS
             Sd

       DESCRIPTION
             One of the kernel configuration files, a Sd file is an
             optional file that executes when the system is shut down to
             perform any cleanup required for an installed kernel module.
             Normally, this is a shell script [see sh(1)].

             When the Sd component of a module's Driver Software Package
             (DSP) is installed, idinstall(1M) stores the driver's Sd file
             information in /etc/conf/sd.d/module-name, where module-name
             is the name of the module being installed.  Package scripts
             should never access /etc/conf/sd.d files directly; only the
             idinstall command should be used.

             The contents of the /etc/conf/sd.d directory are linked to
             /etc/idsd.d whenever a new configuration of the kernel is
             first booted.  On the next system shutdown-and all subsequent
             system shutdowns-the module's Sd file is executed upon
             entering init level 0, 5, or 6 [see init(1M)].
