Combinedelatrpm is your friend here: If you sign the deltas later on, you can use combinedeltarpm to patch the new signature into the deltas. Here's an example: makedeltarpm old.rpm new.rpm delta.drpm sign new.rpm combinedeltarpm -S new.rpm delta.drpm deltasigned.drpm (There's actually another way: you can create a "rpm-only no diff" delta rpm containing just the signature and then use combinedeltarpm to create a delta containing the signature: makedeltarpm -r -u new.rpm newsig.drpm combinedeltarpm delta.drpm newsig.drpm deltasigned.drpm This results in the same drpm as with the -S option.)
