制作可启动的OpenBSD ISO映像

制作可启动的OpenBSD ISO映像(简单修正版)

随着4.0 的发布，新一轮的尝鲜、升级、安装、测试又要开始。对于新手（包括我在内）这第一步便是如何制作安装盘，网上现成的文章成堆，另外还有高手（一般都谦虚地 说自己不是）制作的自动化脚本，极大的方便了制作过程。不过这里引发了两个问题，其一：大部分网上的文章，这第一步从站点下在所需文件的方法就有些问题（也许是我人品问题），所以我才写这个“简单修正”。

其二：人家给你制作了自动化脚本，在第一时间方便了你的安装，但如果你还是想自己动手从最基础的部分入手，想更细化规范的学习，相信这第一步还是挺重要，扎实的基础是日后游刃有余的根本。

制作iso映像系统环境为debian，所需附加软件mkisofs。
第一步：建立文件夹（可选），下载所需文件。
#mkdir -p /home/openbsd/4.0
#cd /home/openbsd/4.0
#wget -crnH --cut-dirs=3 ftp://ftp.tw.openbsd.org/pub/OpenBSD/4.0/i386/
注：你可以按照你的系统环境变通，但剩余容量最好大于500兆，至于建立openbsd文件夹，网上通常写法类似于mkdir -p openbsd/4.0/i386，我这里省略了i386是因为后面的wget下载过程中会自动建立。
说到下载.
第二步：制作iso映像。
这步可以安心的使用网上文章的命令来生成iso映像了，但提醒你注意命令行里的路径。
如果没有mkisofs，先安装吧！
#apt-get install mkisofs
然后开始制作吧！过程相对较短！可能一两分钟吧！
#cd /home/openbsd （确保你在正确的路径）
#mkisofs -vrTJV “OpenBSD40″ -b 4.0/i386/cdrom40.fs -c boot.catalog -o OpenBSD40.iso ./
稍等一会儿，你就会通过自己的操作获得一张标准的可引导安装盘，至于刻录吗？抱歉-帮不上忙，这个也要你自己动手了，不过-估计不用看教程，是不？:~)



最后附上自动安装脚本：

脚本的使用方法：

$ ./mk_openbsd_iso-0.1.sh 3.9 i386
