Tips on preseeding?

[Carsten Agger]

I'm trying to preseed a desktop installation so that users will not be 
prompted for locale or user information.


So I tried modifying the ubuntu.seed file in the preseed/ directory in 
the ISO file.

I tried adding

d-i debian-installer/locale string da_DK

I also tried adding

d-i passwd/make-user boolean false


AND I tried to include the username and password for a sample new user (which, BTW, I don't want), but to no avail -
the installer actually pops up with the username I specified, but asking for a new password.

My objective is to make the process as non-interactive as possible, with only one grace click before the disk is nuked.

But I seem to recall that adding these things to the preseed file would make the installer stop asking. What am I missing?
