Re: Call for testers: zypp tech preview

I just ran: `env ZYPP_SINGLE_RPMTRANS=1 ZYPP_MEDIANETWORK=1 zypper dup --download-only` And trying to run a regular dup (without --download-only) did not display the packages as being already cached. I had to re-download them all again when running `env ZYPP_SINGLE_RPMTRANS=1 ZYPP_MEDIANETWORK=1 zypper dup` Other than that, the upgrade went flawlessly, and these features are really useful. Thanks a lot for the incredible work!
