Well, I'll add the URL to my rediffed patch. It would be nice to drop the
hybrid from making both compression types files and just use one or the
other.

http://dev.unity-linux.org/projects/unitylinux/repository/entry/packages/createrepo/P/createrepo-0.9.8-add-lzma-option-to-generate-primary.xml.lzma.patch

I tried to do it with little luck. I believe the creation of the checksum
for other than gzip files present is needed and then not appending the the
primary,other,filelists_lzma, but rather just that info instead inside
repomd.xml.
