Tried this load out.
Core/Hybrid system using nouveau driver, no Sarah, no flickr photo files.
Tried to create MD and failed.
ifconfig on Core/Hybrid showed alias of eth0:1
eth1 was down. Did ifconfig eth1 up, ifconfig eth0:1 down
ifconfig -a looked better. Tried to pxe boot MD - failed.
Rebooted Core/Hybrid and eth1 down.
Tried ifconfig eth0:1 down, eth1 up.
Lights are on but there's nobody home.
