There are now DVD deltaisos for i386, ppc, and x86_64 available to go
from Preview to Final.

To apply them, one needs the Fedora 11 Preview DVD image, either as an
ISO file, or on an actual DVD. The deltarpm package, which provides the
makedeltaiso and applydeltaiso commands, must also be installed. If one
has the ISO file, run the command
applydeltaiso oldiso deltaiso newiso
where the 3 arguments are the names of the Preview ISO, the deltaiso
from the above links, and the Final ISO, resp. If one has the Preview
on an actual DVD, just put the DVD in the drive and replace the oldiso
argument with "/dev/dvd" (without quotes). On my box with a 2.7 GHz
CPU, the applydeltaiso command took approximately 15 minutes, 25
minutes, and 20 minutes for i386, ppc, and x86_64, resp. It takes
slightly longer if running off an actual DVD instead of an ISO file.
I also created deltaisos to go from F10 Final to F11 Final on i386, ppc,
and x86_64, but due to their size I haven't uploaded them. The
statistics are as follows, with applydeltaiso times measured on my box.
(In some cases, generating them with makedeltaiso took longer, but
that doesn't affect the end user.)
Fedora-10_11-i386-DVD.diso:
size = 3,009,734,924 bytes (81.7% of full ISO)
time to run applydeltaiso: 15 minutes
Fedora-10_11-ppc-DVD.diso:
size = 2,298,836,252 bytes (49.9% of full ISO)
time to run applydeltaiso: 60 minutes
Fedora-10_11-x86_64-DVD.diso:
size = 2,428,936,542 bytes (56.9% of full ISO)
time to run applydeltaiso: 43 minutes
Normally each of these would be approximately half the size of the full
ISO (this was in fact the case going from F9 Final to F10 Final). F11's
i586 package rebuild affected the deltas for i386 and x86_64, with i386
affected severely due to a high percentage of i586 packages (although
the fast apply time might make it worthwhile anyway).
Anyone who has the corresponding DVD images for both F10 Final and F11
Final can generate these using the makedeltaiso command (see the man
page). If there were torrents for some or all of these at
torrents.fedoraproject.org, then any such person could generate the
torrent contents themselves and immediately begin seeding, without
having to download first.
