Automatic installation using preseeding: Changing MAC-address
 

Hi,

I'm writing a preconfiguration file for automatic installation of ubuntu on several computers. The problem is that in order to use DHCP network configuration during the installation process, the computers must not use their native MAC-address but another one. I know that it is no problem changing the MAC-address post-installation by using the procedure described here:

But I have no idea how to do this in a preseeding-file. Any ideas?
