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。
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 $DRV failed\n" >&2 exit 1 fi fi exit 0
删除包含驱动程序的软件包时,必须先运行 rem_drv(1M) 命令,然后删除驱动程序二进制文件和其他组件。以下示例演示了一个使用 rem_drv 命令删除驱动程序的预删除脚本。
#!/bin/sh # # @(#)preremove 1.1 PATH="/usr/bin:/usr/sbin:${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
