Yes, if the dhcp setup of the first network interface is not sucessfull,
subsequent ones are tried until the setup on one succeeds.
But if the setup on the first interface already succeeds, there is no need to
setup additional interfaces (unless explicitly specified with the ip=
parameter).
If your pxe server only listens on the second interface, the dhcp setup on the
first one will fail and dracut should go to the next.

Ok
