Not worth the effort to save space here. You're quick to declare that without really thinking about it. I agree that on a typical desktop setup, 17MiB is pretty insignificant. However for projects like OLPC, which is a downstream user of Fedora, 17MiB can be quite a space hit for simple text files. Now, OLPC has other ways of dealing with this at the moment, but at some point they won't. josh -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
