If I remember correctly, it does not work, when you define a variable and
try to use it in same "block" in this case vars:
Both mysql_os and mysql_el6_base are defined in vars, so when expanding
mysql_el6_base the mysql_os is not yet defined.
And the solution I used was to separate them into multiple vars_files.
