Hi there,

I'm trying to create a random directory, set the current sessions home directory to it, copy the default profile to it and then make sure proper ownership is set. I am trying to create a public terminal kiosk where the autologin is the same via XDMCP. I have created a Default script for PostLogin, which works except after it runs on Login the session is still on the original home directory.

A quote from http://library.gnome.org/admin/gdm/stable/configuration.html.en

After the user has been successfully authenticated GDM will run the PostLogin script. This is done before any session setup has been done, including before the pam_open_session call. This script is useful for doing any session initialization that needs to happen before the session starts. For example, you might setup the user's $HOME directory if needed.

So I created this:

#!/bin/bash

# Note: this is a sample and will not be run as is. Change the name of this

# file to <gdmconfdir>/PostLogin/Default for this script to be run. This

# script will be run before any setup is run on behalf of the user and is

# useful if you for example need to do some setup to create a home directory

# for the user or something like that. $HOME, $LOGIN and such will all be

# set appropriately and this script is run as root.

env > /tmp/aaa

if [ $USER == "google-chrome" ]

then

echo "Inside Loop" >> /tmp/aaa

export HOME=/home/google-chrome-`date +%N | md5sum | awk '{ print \$1; }'`

rsync -avz /home/google-chrome/* $HOME

chown -R google-chrome:google-chrome $HOME

env >> /tmp/aaa

-----

Which I would have expected to have done what I needed but after this is ran the login still reverts back to the original home directory. If I use usermod -d $HOME google-chrome here as well I still end up with the original home directory. Could someone please shed some light on how to do this. I can figure out how to check for duplicates later and how to remove stale ones at the end of the day, but I need to get the session to listen to me first.
