DHCP Option on Amazon VPC

If you enabled DHCP Option on VPC, (Virtual Private Cloud), do not disable the dhcp client process, or disable the network interface file in /etc/sysconfig/network-script/ifcfg-eth0.

Leave the bootproto=dhcp.

Otherwise, for Marketplace Images, I can’t recover the file by  trying attach the volume to another instance. this is Amazon bug.
