Are there any known issues with a 12.04 headless install?
I did an install with a fairly recent snapshot, install started ok and live cd booted.
Once I started the install the external network connection couldn't be found.
I was able to bring it up manually and the install continued but once finished I had to modify /etc/network/interfaces. Instead of auto I had to use allow-hotplug for eth0 and eth1 interfaces otherwise my network cards remained off. On power on the cards are active - link and activity leds blinking, then once lmce started to boot both went dark.
There seemed to be a rogue entry in the file, I spotted a similar one from a recent post from @brononius here http://forum.linuxmce.org/index.php?topic=14051.msg101535#msg101535
its commented out.
udev rules for eth0 and eth1 were pointing to the correct cards.
Then once both interfaces are up I have no routing between them
Core can see external and internal, internal devices cannot see beyond core.
Anything else I can check for errors?
