The -d parameter means that your environment will be preserved, this is generally useful if you want chrooted applications to seamlessly use your X server, your session manager, etc.
现在当你想使用你的Chroot环境时（你可以忽略-c mychroot参数，如果你只有一个或只想使用文件中的第一个时）。-d参数意味着你的环境将被保留，当你想你的Chroot环境中的应用程序想无缝地使用你的X服务器、会话管理器时,这通常是有用的。

代码：全选

 dchroot -c mychroot -d
