Targeting a user home folder

Hi all, I am creating a 10.6.1 Image on a 10.6.1 host. Now I have a bunch of pkgs that target the home of the current User. I already have a user and its home created in my build train before I try to install those pks. I tried to just install and found all the files that are supposed to go inside that users home in /. I was not surprised of this as the installer has no way of knowing which user to target or other put, there is no real current user there during install time. Is there a way to have InstaDMG target a certain users home folder instead of / ? Or do I have to modify my pkgs so that they target /Users/myuser/ instead of current users home? I would prefer a way to just tell it the installer, as otherwise the name of the user has to be hard coded into the new pkgs, which makes it all less flexible. So, anyone knows?
