 Right, this isn't going to work because createrepo is going to see
the .delta.rpm file and think it's an rpm (and it acts enough like one
that this "works").

 You have two easy-ish options:

1. [easy] Pass --excludes='*.delta.rpm' to createrepo. The repo will
work but the clients won't get delta packages.

2. Update createrepo (and likely yum), remove all the .delta.rpm
files, and run createrepo with the --deltas --oldpackagedirs
options. Createrepo will now generate .drpm files in drpms/ relative
to the basedir. ... and if the yum-presto plugin is installed, the
plugin will apply these deltas for yum (if the plugin isn't installed,
the repo will still work as well as in #1).

...doing #2 so that you don't have to regenerate the deltas is likely
possible, but will require more work (likely you'll need to generate
the deltainfo.xml file yourself).
