[pascal.parent at free.fr (Pascal Parent)]

Tested on
- Ubuntu Dapper (6.06LTS) with kernel 2.6.15-28-386 and debootstrap 0.3.3.3;
- Ubuntu Feisty (7.04) with kernel 2.6.20-16-generic and debootstrap 0.3.3.3.


# Why chroot: to be always in a clean Etch (on Mandriva, RedHat, etc...)
# build a debian Etch chroot
debootstrap etch /etch-chroot http://ftp.fr.debian.org/debian
# make some changes on /etch-chroot/root/.bashrc and tar /etch-chroot to keep a
clean chroot under the hand


# ***** first try *****
