Expected results:
yum to find the delta rpms in the expected directory


Additional info:
The feed centos feed has 3 subdirs, ie http://ftp.tudelft.nl/centos.org/6.5/updates/x86_64/:
Packages
drpms
repodata

The pulp repo-mirror has 2 subdirs:
drpms/drpms
repodata

yum presto can't find the delta rpm files in the subdir pulp/repos/centos.org/6.5/updates/x86_64/drpms/drpms
because yum is searching in pulp/repos/centos.org/6.5/updates/x86_64/drpms
