This deltaiso file allows one to generate the Fedora-11-ppc-DVD.iso image if one already has the Fedora-10-ppc-DVD.iso image (either as an ISO file, or on DVD).  This requires the applydeltaiso command, contained in the deltarpm package (available in the Fedora repos).  Using the ISO file, one runs

applydeltaiso Fedora-10-ppc-DVD.iso Fedora-10_11-ppc-DVD.diso Fedora-11-ppc-DVD.iso

If one has the DVD, just mount it and then run

applydeltaiso /dev/dvd Fedora-10_11-ppc-DVD.diso Fedora-11-ppc-DVD.iso

Before downloading the deltaiso, make sure to have the correct, verified, input image.  The SHA1 for Fedora-10-ppc-DVD.iso is

f741dad589b743fc42842c8d6f5a6f511ed3c770 *Fedora-10-ppc-DVD.iso

as found in the readily available signed SHA1SUM file.  If it's on DVD, one can simply do a mediacheck.  After running applydeltaiso, verify the output image.  The SHA256 for Fedora-11-ppc-DVD.iso is

a9e987006c22595a993b88c10ac766aafc4f7b3f5e8278dd4f224d16b49a135f *Fedora-11-ppc-DVD.iso

as found in the signed Fedora-11-ppc-CHECKSUM file (use sha256sum to compute).
