Thanks for the warm welcome and quick response! Have fun at FOSDEM,
unfortunately I don't think anyone from OLPC will be there.

I guess you're referring to the install DVD(s) here - which include
the entire contents of the mirror, makes sense.

In this case I think we want something more akin the minimal install
CD - a specific subset of the packages available, plus installer.
Could you point me towards the scripts used to build that?

To answer your question about the most desirable goal, I guess it is
something like this: we provide a kickstart file that lists the CentOS
repos and our own repo, with the "base" and "core" package groups
selected (plus our own packages listed too), and then we use a tool to
then download all the required packages (but no more), and compose
them onto an anaconda-based install CD.

I guess I have just described pungi there - and maybe that is our
answer. But I have yet to find a report of someone using pungi to
rebuild C6, and pungi is not included in RHEL/CentOS and isn't in EPEL
either. I'd welcome your input on the best way to achieve this.

Thanks,
Daniel
