Adding the --sudo flag to the xdsh command will have xdsh run sudo before
running the command. This is particular useful when using the -e option.
This is required when you input -l with a non-root user id and want that id
to be able to run as root on the node. The non-root userid will must be
previously defined as an xCAT user, see process for defining non-root ids in
xCAT and setting up for using xdsh. The userid sudo setup will have
to be done by the admin on the node. This includes, allowing all commands that
you would like to run with xdsh by using visudo to edit the /etc/sudoers file
and disabling tty requirement by commenting out or removing this line in the /etc/sudoes file "#Defaults requiretty".
