Chuck Anderson (cra(a)WPI.EDU) said:
The infrastructure should either delete and regenerate drpms after
rpm signatures have changed or they should use the code fragment from
to attach rpm
signatures to deltarpms.
That's *really* hard, as there's not any state to track when packages
have been signed out from under the prior delta rpms.
The simplest solution would be to just nuke the old ones by hand.
