Feature added by: Duncan Mac-Vicar (dmacvicar) Feature #312799, revision 1 Title: Safer distribution updates openSUSE Distribution: New Priority Requester: Desirable Requested by: Duncan Mac-Vicar (dmacvicar) Product Manager: Michael Elliott (mge) Developer: ma ds (ma) Partner organization: openSUSE.org Description: 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". Use Case: Bob wants to migrate his server from SLE12 to SLE13. Upgrading the package management stack fails, but he keeps his original system untouched.
