Hi & thanks.
That seems to work, loading a new image and then running rake db:ensure_post_migrations db:migrate seemed to resulted in a fine & healthy new version of container without luncher rebuild - at least for 3.5.0.beta7 to 2025.11.0. That makes me - certainly not just me - thinking…. would it be possible to make such(& anything else need for healthy upgrade) rake part of boot/start of a given, custom container and… would that make sense?
