So how about we offer the user the opportunity to `cp -l /bin /etc /usr 
/lib* /sbin /usr /var /chroots/jaunty` when they upgrade to Karmic?

jaunty /chroots/intrepid --include=ubuntu-desktop` if they install 
Karmic from scratch?  That gives new users similar access to Jaunty.

Finally, how about upgrading debootstrap in Jaunty when Karmic is 
released, so that people can install it in a chroot, and try before they
