# sandbox:        Set up / mountpoint to be shared, /var/tmp, /tmp, /home/sandbox unshared

# chkconfig: 345 1 99
#
# Description: sandbox and other apps that want to use pam_namespace 
#              on /var/tmp, /tmp and home directories, requires this script
#              to be run at boot time.
#              This script sets up the / mount point and all of its 
#              subdirectories as shared. The script sets up
#              /tmp, /var/tmp, /home and any homedirs listed in 
#              /etc/sysconfig/sandbox and all of their subdirectories 
#              as unshared.
#              All processes that use pam_namespace will see 
#              modifications to the global mountspace, except for the
#              unshared directories.
