We're still not done with the %Debian 12 bookworm upgrade or even the %Debian 11 bullseye upgrade, but when we do, we need to start working towards the Debian 13 "trixie" release. If we follow the current cadence, we'll get a release some time around July 2025, with a freeze some time in the end of 2024. We could, therefore, cautiously start upgrading during the freeze.

This issue will start tracking that work, slowly.

Tickets to create/do as next steps here:

• make RFC for upgrade process (team#41990 (closed), previously: team#41245 (closed))
• add support for trixie in container images (previously: base-images#15 (closed) and base-images#17 (closed))
• switch installers to trixie by default (team#42107 (closed), previously: team#41244 (closed))
• automate major upgrades (team#41485)
• trixie updates, first batch: low risk (previously: team#41251 (closed), now team#42071)
• trixie updates, second batch: moderate risk (previously: team#41252 (closed), now team#42070)
• trixie updates, third batch: high risk (previously: team#41321 (closed), team#42069)
• ganeti clusters (previously: team#41254 (closed), team#41253 (closed)) merged in above third batch
• remove support for the image in container images (previously: base-images#19 (closed))
• cleanup Puppet code (team#40747 (closed) team#40723 (closed))
