Since the netinst images have basically the same non-RPM content as the DVDs, I
tried delta-compressing between successive netinst images, and got the following
sizes, which confirms it. This probably has something to do with
https://bugzilla.redhat.com/show_bug.cgi?id=646843 ("images/install.img will no
longer exist in F-15 and newer").
