I meant the install file(s) (hoary.iso or the files that are used to
build the iso), not an installed system.

Hitting Enter at the boot: prompt, selecting Network settings, hitting
Enter at the "Remove media and reboot", and possibly more questions
after the reboot, like "pick nearest mirror."
For testing, I am shooting for this: bios set to boot HD, land, floppy.
script that will render the HD unbootable, then reboot the box. (dd
comes to mind.) Hours later, the install should be complete, with no
human intervention, including loading up the script. The script can
either be launched by cron, or better yet be triggered by "new hoary
image is ready for testing" message.

that the preseed file be pulled from the LAN?

5 min later, lots of hits, can't find the answer.
Whatever it is, it should really be stated here:
Hopfully this isn't what you were thinking of:
"... if the installer can set up the network via DHCP without asking any
questions. You may want to set the installation priority to critical to
avoid any questions while the network is being configured. See Section
5.2.1, “Ubuntu Installer Parameters”. -- debconf/priority=critical"
This will handle my needs, but I think it could be done better. For
instance, if the Admin wants static IP's assigned, he is out of luck. I
think there should be boot option(s) to address "getting the preseed
file" that do not interfere with the box's final configuration. Very
low priority, if it exits, then document it else put it on the Grumpy list.
Another issue: laptops with wired and wireless. The install is being
done over the wire, but the resulting config should just use the
wireless. I could even handle the install being done over the wireless,
but priority=critical is going to make either happen.
ps. number of times I forgot to post to the list ++
