bootp and multiple NICs improvement

[Geert Stappers]

Hello,

On a computer with more then one network interface card,
I encountered strange behaviour.

After the
"""
Calling task_confdir
Kernel parameters:auto rw root=/dev/nfs
Defining variable: root=/dev/nfs
"""
the computer stopped.
But a half minute later it continued with
"""
* No response from BOOTP server
* bootpc failed to locate a network address
/fai mounted from faisrvr:/usr/local/share/fai
Calling task_setup
"""

So:
<screendump>
Calling task_confdir
Kernel parameters:auto rw root=/dev/nfs
Defining variable: root=/dev/nfs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~waiting~~~~~~~~~~
* No response from BOOTP server
* bootpc failed to locate a network address
/fai mounted from faisrvr:/usr/local/share/fai
Calling task_setup
</screendump>



For a newbie to FAI it was very odd.

After investigating what is going on,
it turn out that every is correct, only the user gets poor information.


I made an improvement, a patch is included.
Now the user will see what the computer is doing
and he/she won't see the bootpc errormessages

<screendump>
Calling task_confdir
Kernel parameters:auto rw root=/dev/nfs
Defining variable: root=/dev/nfs
Doing BOOTP requests on all found NICs
eth0
eth1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~waiting~~~~~~~~~~
/fai mounted from faisrvr:/usr/local/share/fai
Calling task_setup
</screendump>




Kind Regards, Geert Stappers
