# PURPOSE
#  This script sets up LTSP LDA (Local Drive Access) with LtspFS.
#  Specifically, it setups the mounts.
#
# EFFECTS
#  The terminal's disks will be mounted as <~/drives>.
#
# VERSION
#  This script developed for LTSP version 4.1.
#
# INSTALLATION
#  1. Run this script from </usr/share/gnome/default.session>.
#
#  2. Setup $LOCALDEV with proper permissions.  For example:
#      mkdir /mnt/localdev
#      chgrp users /mnt/localdev
#      chmod g+rwx /mnt/localdev
#
#  3. Add each terminal user to the group fuse for Fedora Core 4 (and maybe 
#     other distributions).
#
# NOTE
#  This script runs as a normal (non-root) user.
#
#  Why mount under </mnt> and link to <~/drives>?  If </home>
#  is a NFS file system with root squashing, then you cannot
#  mount directly to <~/drives>.
