Flynx: You are right, I should use /.debian instead of /debian as my default mount point in my script. This will not cause a problem in new installs, because I have changed this in the ~/.chroot config file, but it will cause a problem for users updating from previous versions, because it doesn't update previously installed .chroot files. As a workaround, change the "CHROOT=/debian" line to "CHROOT=/.debian" in your /home/user/.chroot file.
