Comment 3 for bug 321341

There is either a regression in karmic or this was never fully fixed. It is not possible to perform an automated install in oem-config mode as the "Who are you page?" is still displayed. The hostname field is populated but not disabled like the username. However, I think the real reason this page is being displayed is because its looking for a password for the oem account. Manually seeding the related questions (both using a password and also using no password) seems to have no effect - the page is always displayed.
