I've made available deltaisos for the Fedora 12 Beta TC->RC1 and
RC1->RC2 DVD ISOs for i386, ppc, and x86_64. In addition, there is a
deltaiso for the Fedora 12 Beta RC2 i386 DVD ISO, from the old,
incorrect (due to compose error) version to the correct version. The 3
TC->RC1 disos are roughly half of the full ISO size, which is much
larger than they ought to be (should be more like 5-10%), but
unavoidable due to Rawhide deltaisos currently being nonfunctional (I
built these on F11). The remaining disos are 1-3% of full ISO size. My
upstream bandwidth is only 768 Kb/s so I can't promise much as far as
seeding TC->RC1. These are available at
