+This script now installs the nvidia-persitenced daemon.  For details, see

 Several useful utilities are included: nvidia-xsettings, nvidia-smi, and
 nvidia-settings.  Please refer to the Nvidia documentation and man pages
 for details and usage.
 
 For CUDA/OpenCL to work after reboot, and for utilites such as nvidia-smi,
 you might need to include the following line in your /etc/rc.d/rc.local:

     This is benign and due to the nvidia installer not being very smart.

+The driver now includes rc.nvidia-persistenced as an option.  While it can
+be run as root, it is more secure to run it as an unpriveleged user, so we
+run it as user nvidia.  Create the nvidia user and group with the following:
+
+    # groupadd -g 365 nvidia
+    # useradd -u 365 -g 365 -c "Nvidia" -d /dev/null -s /bin/false nvidia
+
+To activate the daemon, add the following to /etc/rc.d/local:
+
+# Start the nvidia-persistenced daemon:
+if  [ -x /etc/rc.d/rc.nvidia-persistenced ]; then
+    /etc/rc.d/rc.nvidia-persistenced start
+fi
+
+and then 'chmod +x /etc/rc.d/rc.nvidia-persistenced' to make it executable.
+
+Add the following to /etc/rc.d/rc.local_shutdown:
+
+# Stop the nvidia-persistenced daemon:
+if  [ -x /etc/rc.d/rc.nvidia-persistenced ]; then
+    /etc/rc.d/rc.nvidia-persistenced stop
+fi
+
+NOTE: This may not work on all systems.  If you encounter problems
+with it, just 'chmod -x /etc/rc.d/rc.persistenced' and it will no
+longer load.  YMMV.
