Sous-système Debian

debootstrap sarge /subsystems/subsystem_name
chroot /subsystems/subsystem_name

You now run in an independent Debian system, very useful for tests and also security.

Copier /etc/hosts dans le sous-système.

Some things need to be fixed:

* MySQL will try by default to bind port 3306 on the loopback (127.0.0.1). Use the skip-networking keyword in /etc/mysql/my.cnf to avoid that, or else you won't be able to run several mysql instances in different subsystems.
