在SCO下直接使用ISO镜像安装软件的方法

  【IT168 服务器学院】以赛博中文的ISO文件为例。

   你可以使用ISO文件在SCO下直接安装,但必须保证你的机器上已经安装了光驱,并且在核心中含有CDROM设备,即hwconfig -h 列表中有CDROM信息。接下来你可以通过下面的步骤来处理:

    cd /dev
    mv cd0 cd0.bak
    cd /tmp (此处假定你的cyber.iso放在/tmp目录中)
    marry -a cyber.iso
    cd /dev
    ln -s /dev/marry/tmp/cyber.iso cd0

    l cd0 显示结果如下:
    brw-r----- 1 root sys 76, 1 Feb 26 10:45 cd0@

    mv rcd0 rcd0.bak
    mknod rcd0 c 76 1 

    l *cd0 显示结果如下:
    brw-r----- 1 root sys 76, 1 Feb 26 10:45 cd0@
    crw-r--r-- 1 root sys 76, 1 Feb 26 10:48 rcd0

    custom
    选择安装介质时选CDROM就可以安装了。
    记得安装完成之后

    cd /dev
    rm cd0 rcd0
    mv cd0.bak cd0
    mv rcd0.bak rcd0;
    marry -d /tmp/cyber.iso

    恢复你的光驱设备,否则你的光驱不能使用啦!

补充marry的说明:

marry -- marriage driver

   The marriage driver allows a regular file to be treated as a device. It does not drive any hardware directly, but it redirects reads and writes on its device to the associated regular file.

   marry(ADM) uses the marriage driver to associate a block special device file with a regular file. The regular file may then be accessed through the block device node created below the /dev/marry directory, or through a character device node.

  swap(ADM) uses marry to allow a regular file to act as a block device for swapping. marry may also be used to allow a regular file to act as a block device for mounting.
