Wow, you seem to be really singing the praises of chroot. I have a spare 10gig partition on my hard drive. I originally considered simply dual-booting Etch and Lenny, or Etch and Feisty, or something similar. Perhaps instead I will make it a chroot jail for Lenny. Big question answered: you can run X clients (applications) on your local, non-chroot Xserver (display). So, again, it is a completely separate operating system installation, running on the same kernel as the active, base OS? So how do you handle the /boot partition? Do you have to redirect to the active kernel, or is this sort of automatically taken care of by debootstrap? (I have never used debootstrap). On Tuesday 31 July 2007 7:25 pm, Andrew J.
