Downstream forks are currently updated manually when there are changes (https://tracker.pureos.net/T1012). It would help if an auto forward porter would track synchrotron and

• grab the new package from debian
• apply pureos changes
• check if package still builds and passes

This would reduce busywork. This doesn't necessarily be part of laneakia but could happen in e.g. gitlab. There's prior art here by several other downstreams one could build on.
