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
