I have used this during Fedora 13 but only to see how it works. Not
working was never a thought. :-)
What you just explained is how I had understood this working.
And yes Andre has done an excleant job of making and providing deltaisos.

Should also mention that since the difference between zsync and deltaisos is
either downloading changed RPMs in full vs. using deltarpms on them, this means
that if both were provided, then people with either sufficiently fast

To clarify, this is theoretical. The Fedora project is *not* creating
official deltaisos right now. However, any deltaiso should build into a

Deltaisos won't save significant space when used on Live images. Having said

Is it possible to make a deltaiso without having both the older ISO and
the Newer ISO on a local system.
Example. Fedora-14-Alpha-x86_64-Live.iso was downloaded. A
Fedora-14-Alpha-2-x86_64-Live.iso is availible for download.
Can a deltaiso be made without downloading the newer ISO?

I've made DVD deltaisos available which update from Fedora 12 to the

Isn't the basic strength of lzma a very big dictionary window?

No it cannot. Recompressing something that is already compressed,
normally ends in growing the final result.

Generally speaking, trying to compress something that's already
compressed doesn't gain you anything.

Starting with Fedora 12, RPM packages are compressed using XZ instead of
gzip. As a result, the F12 ISOs are smaller:
F11 DVD sizes (bytes):
i386: 3683829760
ppc: 4606894080
x86_64: 4268124160

Dear fellow users,
I want to pose a quick questions. I know Mr. A Robatino posts deltaisos
regularly which amounts to a certain amount of savings when one downloads a
deltaiso. Although I have never downloaded one, I ask if one can save more
bandwidth if we use lzma compression. I ask this
