Delta RPM & presto during anaconda upgrades

[Alexander Todorov <atodorov redhat com>]

Hi all,
I've noticed that delta rpms are generated for the updates repository in F11 and
not the main one (used for install). Does anyone know if delta rpms will be
generated in the main repo for F12?

Even if they are not generated people upgrading to newer Fedora release after
the initial release date will likely activate the updates repo as well. IMHO
upgrades should take advantage of delta rpms and include the yum-presto plugin
in the anaconda-yum-plugins package. How that plays with pre-upgrade ? (i've
never used it).

Please let me know what do you think about this idea.

Thanks,
Alexander.
