驱动程序打包

软件的标准交付方式是创建一个包含所有软件组件的软件包。软件包为软件产品所有组件的安装和删除提供了一种受控机制。除了用于使用产品的文件以外，软件包还包括用于安装和卸载应用程序的控制文件。后安装和预删除安装脚本即为两种此类控制文件。

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

软件包预删除

删除包含驱动程序的软件包时，必须先运行 rem_drv(1M) 命令，然后删除驱动程序二进制文件和其他组件。以下示例演示了一个使用 rem_drv 命令删除驱动程序的预删除脚本。

#!/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
