dual ethernet, single FAI

[Steffen Grunewald]

Hi,

it's Friday, and obviously everyone has already left for the weekend ...
so I have no other choice than trying the stuff out myself :-/

That's been done long before - in fact, even the single-homed nodes waste
some seconds trying to PXE from the unused port.

Did that.

Obviously it did...

Yes, and I was able to watch the installation proceed and finish (I had 
removed the "reboot" part from the parameter line), to CTRL-C into a
shell, look around (in /tmp/fai/error.log, and /tmp/target/boot), and
eventually reboot the node by CTRL-D'ing twice.

Now for some unknown reason GRUB is stuck with
GRUB loading, please wait...

I guess that's something to investigate on Monday, using a sysinfo boot.
Leaving for the weekend now :-) (oh wait, first "ipmitool chassis power
off" that beast...)

Cheers,
 Steffen
