# Description   : I was strugging with running the stack.sh file as a vagrant user. Though I run the file using
#                 "sudo su vagrant" the installation of devstack setup was failing with an error "/root/.my.cnf" 
#                 permission denied. I was looking for a solution and the below mentioned site had a solution to 
#                 run certain parts as root and certain parts as vagrant. This was really a blessing.
