如何在移除deb包时，不去移除系统原有的文件？

比如gati-cts_1.0_all.deb是我自己做的一个包，会将一个文件放到tomcat里
#dpkg -c gati-cts_1.0_all.deb

drwxrwxr-x root/root         0 2007-04-25 19:58 ./usr/
drwxrwxr-x root/root         0 2007-04-25 19:58 ./usr/local/
drwxrwxr-x root/root         0 2007-04-25 19:58 ./usr/local/apache-tomcat-5.5.17/
drwxrwxr-x root/root         0 2007-04-25 19:58 ./usr/local/apache-tomcat-5.5.17/webapps/
-rwxr-xr-x root/root  17351054 2007-04-25 19:58 ./usr/local/apache-tomcat-5.5.17/webapps/TestResultMonitorWS.war

而移除该包的时候，系统总会尝试去移除整个tomcat目录，然后给出警告说目录不为空，无法删除.

怎样才能只移除特定文件，或者不显示警告信息，谢谢

它就没有删除其它包的文件啊。。。

不显示警告用什么什么参数
