工作中，有時需要移植一些已經安裝過的Solaris包，或者對已經安裝後的包進行修改，但一時又無法找到原來的安裝包。系統升級時，有時也常常涉及到對原來系統的備份問題，這時需要一些能夠對原來的安裝包進行備份，又能夠在新系統上進行安裝的工具。Solaris本身並不提供直接的工具用於包的移植。
但Solaris在安裝本身通用的PKG包時，會產生兩個與安裝包相關的文檔/上錄，分別在/var/sadm/pkg/下和/var/sadm/install/contents中，通過對這兩個文檔進行解析，可以實現對Solaris包的反安裝，這在實現系統升級時尤其有用。
以下腳本會在當前的運行目錄下產生壓縮的系統安裝包，Copy/Paste本腳本到Solaris機上，運行後輸入需要反安裝的包名即可。歡迎大家測試。
