Comment 2 for bug 1276064

Another analogous problem with this preseed: although I attempt to enable root logins, and I attempt to defeat creation of a non-root user, and even though in desperation I have set a full name and username for the non-root user (both 'deleteme'), I am still prompted for a full name and username for the user.
It's like the 'user-setup-udeb passwd/username string deleteme' and 'user-setup-udeb passwd/user-fullname string deleteme' directives don't do anything whatsoever - and again there's no indication why.
I could work around this by enabling root logins and deleting the user in a late command, but I shouldn't have to do that.
In other preseeds (to be attached), these exact same directives *do* defeat creation of a non-root user.
So it's not as simple as these directives always getting ignored. Something other mystery factor controls whether they do anything or not, and the installer's not telling me what that mystery factor is.
