This How To will show how you can install Debian Etch and basically any Debian based distribution from a chroot environment. This way you don't need to download the (net)install CD, neither to burn it.
This is as well a good training in order to understand how a debian system works.
It's a long time since I ran debian on my system, I'm kind of missing it and decided to use the 5G I got left on my hard disk to install Debian Etch.
I wanted to install it directly from my Ubuntu Dapper environment. It used to be quite easy in the past as you could use the base-config which would guide you through the installation process, but recently (2 month actually), Debian Installer Etch beta 2 was released, here is an excerpt of Debian News March 15th, 2006:
March 15th, 2006
The Debian Installer team is proud to announce the second beta release of the installer for Debian GNU/Linux Etch.
Improvements in this release of the installer include:
- base-config has been pensioned off: the installation is now done entirely before the reboot. Finally the entire Debian package installation process runs behind a user-friendly progress bar.
Well, the debian installer is now run while on the install cd and base-config was removed from the repository, this means that I will have to do the job done by base-config, basically, setting up locale, console-data, timezone, network and fstab.
2. Preparing your system
The first thing you need to do is to prepare a partition to host your new system. Your filesystem might be more or less complex (having separate /boot, /usr, /var ...), in my case, as I don't have much space left, I will create a / partition on sda11 of type ext3 and a separate /home partition (the one I'm already using on my Ubuntu Dapper system) which is located on partition /dev/sda5 and is of type reiserfs. The swap partition will be the one I use on my running system, namely: sda9.
So here we go, we have to format /, mount / on our file system and prepare our future debian filesystem using debootstrap which is a tool to bootstraps a basic Debian system.
Let's go to it, open a terminal and type:
root@laptop:/# mkdir /mnt/debian
root@laptop:/#mount /dev/sda11 /mnt/debian/
now, the filesystem is prepare and we have mounted our system on /mnt/debian, now, we install a basic system with debootstrap:
root@laptop:/#debootstrap etch /mnt/debian/ ftp://ftp.de.debian.org/debian/

I: Base system installed successfully.
Done! Now we are going to chroot (a tool provided by the package coreutils), chroot runs command or interactive shell with a special root directory, in order to let our new system being informed of what is in the system, we need to mount /proc filesystem:
root@laptop:/#mount -t proc none /mnt/debian/proc
Let's carry on with the configuration.
