can you specify the need per OS?
are you seeing specific load on certain jobs that are lacking specific OS?
if we're using mock for building packages, i guess the OS is less relevant right?

I'm asking, since this is currently a manual process which will require a few days
of work for 1-2 engineers, and i wonder if it's critical or can wait till we have something automatic
for it.
and since this requirement is dynamic and will change in time as the version progress,
it's something we'll need to do on a regular basis, so its best for us to automate the process
asap.

we're already working on an automated solution for it, hopefully won't take too long 
to activate it.
