Just for my education - when we're talking about name persistence, there
needs to be *something* that is permanent, otherwise there won't be a way
to tie a configuration to any piece of hardware. And if devices keep changing
all the time, then we're kinda out of luck if we need to tell them apart.

So, will vmware leave at least the MAC address intact? Or are we really
just talking about a configuration like "I really don't care how the NIC
identifies itself - I just want to make it come up with DHCP"?

Regards
Olaf
