title: Username 'root' can be changed in mysql or i can suppose there always be a user named 'root' having all privileges?
body: <p>Question explain itself. In mysql i can <em>always</em> suppose there will be a user named 'root' having all privileges or the name can be changed?
  I'm writing a shell script that needs to do some administrative task on a database and i was guessing if i have to ask user only root password or root username too.</p>
