Description of problem: Deltarpm doesn't store the arch of the old package in the drpm file. When you try applydeltarpm drpm newrpm, it will fail half of the time on an x86_64 system where two rpms have been installed with the same name, version and release, but different arches. This makes yum-presto barely usable on an x86_64 system. Version-Release number of selected component (if applicable): deltarpm-3.4 How reproducible: Always Additional info: Michael Schroeder, the maintainer of deltarpm has sent me a patch that allows the user to use the "-a" option to specify the arch the drpm is made for. This is only a workaround, but he has promised that it will be available in the next version of deltarpm.

Patch looks sane to me. Fixed in 3.4-2, thanks!
