rawhide is not currently installable.
Two problems, one is a showstopper.
1) anaconda fails to initialize the RPM database when reading from an NFS repository. It may be any repo, but only NFS tested.
2) I like the new screen font, except that the first printouts and static texts are just garbage bits. stuff that I can mouse over self-correct, but the labels and descriptive text is still random bits.
