That looks promising. Should we spun a differently named branch to avoid people sending core-updates change? This was discussed in the past and agreed to (main branches do not *freeze* themselves), instead we use git to branch to our will. We could perhaps then add a 'core-updates-fixes-only' branch to the CI, in which we'd try to restrict core changes as much as possible, keeping the rebuild stress low for Berlin. How does that sound? -- Thanks, Maxim
