This is fine. The first DHCP request comes from you NIC, the second
from the kernel, which cannot get the ip address from the NIC. But I'm
wondering why it wants a certain ip address which is also a wrong address.
Did you specify anything related in your pxelinux.cfg?

I don't know. Maybe something weird in your dhcpd.conf. Try with the
dhcpd.conf example supplied by the fai-doc package.

Write a hook (for example extrbase.MYCLASS), which calls the
dhcp-client. But you have to decide when you need the second interface
and maybe rename the hook so it's called earlier.
