Improving dist-upgrades reliablity and user experience

2012-10-31 10:00..10:45 in B3-M1

A lot of our users do full dist-upgrades rather than reinstalling for every single release. It's a good thing that we support it and a very important feature, unfortunately it's a rather fragile feature, especially when doing LTS-to-LTS upgrades.

This session is here to discuss ways to allow for faster, more reliable dist-upgrades.

Some ideas: - Split download from upgrade - Run upgrade in a minimal failsafe environment - Use snapshotting features, overlayfs, ... when available to "test" the upgrade - Detect known issues prior to upgrade and warn the user about them
