And Smart also supports lzma/xz, since it just uses the file suffix.
I was under the impression that you had patched createrepo for lzma ?
And it should be simple to support both of .lzma and .xz compressions
by using PylibLZMA in yum, or liblzma directly for yum-metadata-parser.

The concern was that if the type wasn't changed, then older versions
of yum would try to parse the lzma/xz as uncompressed and just get
checksum errors. So it was more for "compatibility" than anything ?
But the "primary_lzma" wasn't my idea, since it came from openSUSE.
