Sending patches slows down the testing process and is not tenable. you should watch the commits on spin-kickstarts list where all commits are sent if you care to follow the changes. > (Dennis and others, can you send patches to the list for review? > This issue would have been more obvious if I'd noticed the changes > going by) > > A really critical variable here is whether or not libvirt guest > autodetection works.
