Sun Solaris 安装包的反安装实现

工作中,有时需要移植一些已经安装过的Solaris包,或者对已经安装后的包进行修改,但一时又无法找到原来的安装包 。系统升级时,有时也常常涉及到对原来系统的备份问题,这时需要一些能够对原来的安装包进行备份,又能够在新系统上进行安装的工具 。Solaris本身并不提供直接的工具用于包的移植 。
但Solaris在安装本身通用的PKG包时,会产生两个与安装包相关的文档/上录,分别在/var/sadm/pkg/下和/var/sadm/install/contents中,通过对这两个文档进行解析,可以实现对Solaris包的反安装,这在实现系统升级时尤其有用 。
以下脚本会在当前的运行目录下产生压缩的系统安装包,Copy/Paste本脚本到Solaris机上,运行后输入需要反安装的包名即可 。欢迎大家测试 。
