I suspect that there are others of these available out there, but I
thought that I'd send out the script I've cobbled together to start and
stop flowvisor on a CentOS system. Feel free to send back any
improvements you might make - I'd be happy to have them. Note that you
may need to modify some of the variable settings at the top of the file
to match your installation.
As all of you CentOS folks already know, the attached file is intended
to live in /etc/rc.d/init.d and should be added to the system startup &
shutdown order with 'chkconfig --add flowvisor'....
