Can’t login on new image

I have been using the past 2 days to get this working. What I did: - This is on a Mac Pro (latest model) - Using the Mac Pro install disk 1 - Using InstallerChoices.xml to prevent printer drivers, languages and Bundled Software from installing - Installing QuickTime 7.4.1 update - Installing 10.5.2 update - Installing LeopardGraphicsUpdate - Installing SecurityUpdate2008-001Univ - Using custom instauser installer, that installs a user (UID 499) as well as a StartUp script to create the user folder in /var/, as well as a preference com.apple.loginwindow.plist (so that I get name and password field to login to) The end result is this: - Machine boots up fine, and show login window correctly. - I can't login to the admin account - Trying >console, and I can now login to the admin account - but the StartupScript have not yet run, as I'm told I do not have a home. - Run the instauser StartupScript - Reboot - stil cannot login - Going to console and can login, now with a home folder Together with all this cups is crashing all the time (about every 10th second, printing a line on the console each time), but I did not install printers (maybe this came from one of the updates). system.log also have some "strange" lines, that i do not remember I see on a working system. My own notes to the above: I realise now, that maybe the QuickTime update is not needed, as it's already included on the Mac Pro image, but I have also tried with a fresh 10.5 image at first, with the same result. The reason I give the user UID 499 and place it in /var is that I do not want it to show up in the list of users anywhere, nor in the /Users folder. Can anyone enlighten me before I return to the old way of doing images?
