If you have ever used a unix/linux system you probably know about the chroot command. I have several testing chroot directories in my debian systems but I had never really taken advantage of such a great tool as debootstrap is, at least consciously.
This week I installed sid in a chroot in wheezy and I'm really enjoying the fact that I can play with it as much as I need to without risking breaking things badly.
I heard (on the net) that lxc are even better. I quote:
described as “chroot on steroids”
I once tried installing a container in wheezy but I didn't succeed, I'll try again at the weekend.
