Safer distribution updates
Currently the documentation says that to do a distribution upgrade you should first update your software stack to the target distribution, then do a zypper dup. The software stack update can already kill your system.
zypper could allow an option that makes it first install a miniroot containing the update stack itself, then automatically switch over to the miniroot to do the "zypper dup".
