Robert,

The problem here is that multiple teams are involved and every additional 
step does not only make the whole installation harder, it makes it more 
error-prone.

The 2 datacenters are 400km away, the teams speak another language.

And frankly, if we specify the MAC address and we can have a proper 
network going to download the kickstart file. We should be able to do the 
same for the second phase (downloading the media/packages).

Adding a step where room-management is going to repatch the system is 
highly undesirable, because it should be avoidable.
