Wanted to let folks know about a community project focused on CentOS/rhel deployment. The project is called CentOS Studio. The idea is to provide a general platform for assembling and testing rpm package repositories containing existing rpms, user-provided content and, optionally, anaconda installation images. The repositories can be used with yum, as usual, or to install complete systems from boot images, over the network, etc.
A stable beta release of the CentOS Studio product is available at www.CentOSstudio.org.
Hope this may be useful to some.
