This idea seems like a really nice idea, and one that in some other form is requested by users/testers. I would like to add to points: * if all tests go OK, and we end up with this on koala (to late for FFe on jaunty, right?), a checkbox when using update-manager -d / cli question on do-release-upgrade to use Sandbox would be much nicer then running all that code. * to save the system state prior to upgrade, so that a user can restore the system if even after successful package upgrade, some application/kernel/driver upgrade doesnt go as good. -- Hi, I'm BUGabundo, and I am Ubuntu (whyubuntu.com) (``-_-´´) http://LinuxNoDEI.BUGabundo.net Linux user #443786 GPG key 1024D/A1784EBB http://BUGabundo.net ps.
