Johan has posted a new hydration kit for 2012 ConfigMgr RC1.
Deployment Research > Blog – The Hydration Kit for ConfigMgr 2012 RC1 is available for download
Here is a download for deploying a complete ConfigMgr 2012 RC1 infrastructure in either Hyper-V or VMware: One Domain Controller and one ConfigMgr 2012 RC1 member server – Including pre-requisites like .Net Framework, SQL 2008 and IIS – all fully automated.
Once configured, the total build time for the full ConfigMgr 2012 RC1 lab environment is about 1.5 hours (on my laptop).
