软件包后安装

将包含驱动程序二进制文件的软件包安装到系统中之后， 必须运行 add_drv(1M) 命令。add_drv 命令将完成驱动程序的安装。通常，add_drv 是在后安装脚本中运行的，如以下示例 中所示。

#!/bin/sh
#
#       @(#)postinstall 1.1

PATH="/usr/bin:/usr/sbin:${PATH}"
export PATH

#
# Driver info
#
DRV=<driver-name>
DRVALIAS="<company-name>,<driver-name>"
DRVPERM='* 0666 root sys'

ADD_DRV=/usr/sbin/add_drv

#
# Select the correct add_drv options to execute.
# add_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 attach the driver
    #
    ADD_DRV_FLAGS=""
else     
    #
    # On a client, modify the system files
    # relative to BASEDIR
    #
    ADD_DRV_FLAGS="-b ${BASEDIR}"
fi       
 
#
# Make sure add_drv has not been previously executed
# before attempting to add the driver.
#
grep "^${DRV} " $BASEDIR/etc/name_to_major > /dev/null 2>&1
if [ $? -ne 0 ]; then
    ${ADD_DRV} ${ADD_DRV_FLAGS} -m "${DRVPERM}" -i "${DRVALIAS}" ${DRV}
    if [ $? -ne 0 ]; then
        echo "postinstall: add_drv $DRV failed\n" >&2
        exit 1
    fi
fi
exit 0
