In addition, you can install dchroot and switch between various chroot enviroments. If you modify in your chroot enviroment, the ~/.bash_profile (make sure the debian_chroot is defined) and put a line describing the chroot in /etc/debian_chroot, you can have your prompt tell you what chroot enviroment you are in. Handy if you have multiple chroot enviroments. John -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
