 Replying to [comment:5 notting]:
 > mash just uses the createrepo default - is there a reason that couldn't
 change?

 I'll gladly create an upstream ticket for it if desired. But please note:

 1. it most likely won't be done before F19 branches
 1. I assume the --xz option was added for the very reason that
 distributions might easily change the behavior to suit their needs. It
 also hints that there was a reason to stay with gz by default.
 1. I think the default compression method won't be changed in createrepo
 unless all important distributions that use it have their package managers
 adjusted to work with xz. Remember, this is not just about Fedora and yum.
 I have no idea what is the state of xz support in other package managers.

 I think it makes sense to add --xz to Fedora rel-eng scripts now and also
 create an upstream ticket, which will probably take years to be resolved.
