定制Linux LiveCD的研究与实现

Research and implementation of custom Linux LiveCD

摘要:

针对每次安装Linux都要根据需要重新配置系统环境的问题,提出一种在Linux下定制LiveCD 的方法。Ubuntu是Linux众多发行版中的一种,在Ubuntu下制作LiveCD最常用的方法是使用UCK和Reconstructor,但是这两种方法都不能把当前系统生成LiveCD,鉴于此,研究并实现使用Live Ubuntu Backup在Ubuntu下定制LiveCD的方法。该方法首先将配置好的操作系统备份成一个squashfs文件,然后用该squashfs文件替换掉原始系统中的squashfs文件,最后将符合用户需求的系统生成LiveCD。实验结果表明,该方法满足定制LiveCD的要求,并且最终生成的LiveCD运行稳定,达到了预期要求。

Abstract:

In order to solve the problem of reconfiguring the system for installing Linux every time,a method of costom LiveCD under Linux is proposed.Ubuntu is one of many Linux distributions, the most commonly used method to produce liveCD is to use UCK and Reconstructor in Ubuntu,but both methods can't generate LiveCD from the current system.In view of this situation,put forward to produce liveCD in Ubuntu using the LiveSUbuntuSBackup,this method backup configured operating system into a squashfs file first, and then use the squashfs file replace squashfs file in the original system, and finally get liveCD from the system which meets user requirements.The experimental results show that the proposed method in this paper can satisfy the demands for custom LiveCD,and generated LiveCD running stable and achieve the expected requirements.
