@TimoWilken could you cross check?
@sy-c I guess we do not need the RPMs for DA anymore...

I hope so, I have not seen one for the past 5 years ;) please go ahead and cleanup related features as you need !

That's the answer I wanted... ;-)

Do we need this BUILD_DATE calculation anyway?

As far as I can tell, it creates a new build area every 3 days (not sure why), then later in the script it loops through all the build areas to find its own one (the $WORKAREA/$WORKAREA_INDEX/current_slave stuff), I guess to deconflict different "build slots"/executors on the same builder (why not use Jenkins' $EXECUTOR_NUMBER variable?).

If we want a new build area every once in a while, why not e.g. date -u '+%Y-%m-%d' for a new one every day or date -u '+%Y-W%W' for once a week?

If you want to keep the logic as-is, I'd remove the extra wrapping $(echo ...):

BUILD_DATE=2015$(("$(date -u +%s)" / 86400 / 3))

No, indeed we can probably drop everything.
