When removing a package that includes a driver, the rem_drv(1M) command must be run prior to removing the driver binary and other components. The following example demonstrates a preremove script that uses the rem_drv command for driver removal.
#!/bin/sh
#
# @(#)preremove 1.1
PATH="/usr/bin:/usr/sbin:${PATH}"
export PATH
#
# Driver info
#
DRV=<driver-name>
REM_DRV=/usr/sbin/rem_drv
#
# Select the correct rem_drv options to execute.
# rem_drv touches /reconfigure to cause the
# next boot to be a reconfigure boot.
#
if [ "${BASEDIR}" = "/" ]; then
#
# On a running system, modify the
# system files and remove the driver
#
REM_DRV_FLAGS=""
else
#
# On a client, modify the system files
# relative to BASEDIR
#
REM_DRV_FLAGS="-b ${BASEDIR}"
fi
${REM_DRV} ${REM_DRV_FLAGS} ${DRV}
exit 0
