Feature changed by: Joachim Werner (joachimwerner) Feature #312799, revision 9 Title: Safer distribution updates openSUSE Distribution: Evaluation by project manager Priority Requester: Mandatory Requested by: Michael Schröder (mlschroe) 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 (or from SP1 to SP2). Upgrading the package management stack fails, but he keeps his original system untouched. Joe wants to migrate his desktop from openSUSE 12.1 to 12.2. Business case (Partner benefit): openSUSE.org: Failsafe migrations for SLE + Discussion: + #1: Joachim Werner (joachimwerner) (2013-08-06 20:06:57) + If we decide to actually allow "online" zypper dup on SLE 12 this is + indeed mandatory. In case the decision is made that we should always + boot into an update system for a distribution update, this is still + nice to have for openSUSE, but would be downgraded for SLE. -- openSUSE Feature: https://features.opensuse.org/312799
