For machines that do not have a MAC in hardware and with drivers that don't
generate a random one in the kernel, this init script will replace the string
RANDOM_MAC in the network/interfaces file with one generated with "ranpwd -m".
Care is taken to ensure multiple interfaces can use RANDOM_MAC and receive
unique addresses. ranpwd generates MACs with the locally administered bit set
and the multicast bit disabled.

Otherwise looks good, feel free to add my SOB.
