Ah yes, that’s a problem.  Maybe it should have UUIDs or something in
addition to those database IDs; or maybe the Data Service can use, say,
derivation + ID as a unique ID for Cuirass builds?

Indeed.  :-)  Well, I do hope that status = failed really means build
failure; seems we’re not completely done with the infamous “missing
.drv” bug though, and that’s erroneously reported as “failed”.
