Hi. kerberos-configs also hasn't been uploaded in 555 days:-) It's a fairly static package, and I don't think reproducible builds adds enough value to this package to justify an upload just for this patch. That said, I've reviewed the patch, and it seems entirely reasonable, so I will include it in the next upload.
However, looking at the outstanding bugs, #741051 does seem worth dealing with. I'll try to get to something including this patch and that bug in the next couple of months. I'd prefer not an NMU for this issue alone, because the effort of integrating the NMU changes seems lower than the value of getting this package to build reproducibly, but if there is an NMU for another reason I'd recommend including this patch.
