TIP: These `debootstrap`(8) or `debootstrap`(1) are used to http://www.debian.org/releases/stable/installmanual[install Debian] by the Debian Installer. These can also be used to install Debian to a system without using a Debian install disk, but instead from another GNU/Linux distribution. |

You can run another login process on a separate virtual terminal where you can log in to the chroot system directly. Since on default Debian systems `tty1` to `tty6` run Linux consoles and `tty7` runs the X Window System, let\'s set up `tty8` for a chrooted console as an example. After creating a chroot system under "`/sid-root/`" instead of "`/var/cache/pbuilder/build/`" by following steps you learned from `pbuilder`(8), type from the root shell of the main system: |
