livemedia-creator has been around for a few years, we have not used it
previously as it was not possible to run in mock and ensure that we use the
correct versions and be able to reproduce builds.  koji today can not use it
and we prefer to make the livecds in koji so we can take advantage of host
parallelisation we want to ensure we can continue to make the artifacts for
the life of the release in the event we need to make updated images for
critical security bugs.  in order to switch the kickstarts will all need some
significant tweaking. hence the desire to keep the old tools available and

​I see. That makes a lot of sense.​

We will deprecate them as we land livemedia-creator support in koji. They will
be removed from the code base at the end of next year

​Okay, good. I just don't want to see Koji growing to be more complex than it already is. :)​

We can not use them today as the code i not written for koji integration and
if it showed up tomorrow it would be completely untested and may not allow us
to produce the Fedora 23 lives, in addition to the work that will be needed to
convert the kickstarts. we are doing it as aggressively as we can with the
resources that we have on hand.

​I understand.​ I didn't realize that kickstarts need to be altered to be used for the new tools. I'm guessing the new tools use DNF/hawkey as a resolver now?


Thanks for the feedback

​No problem. I'm glad you responded so well to it. :)​
