Actually the MySQL 's root pasword need to be given to the Typo installer to create new databases , but in our case we can't give it , because , it will be reset during installation. So inorder to give an normal user permission to databases that are going to be created by installer , the database is created is created initially then permission is given to user and then it is deleted.
Don't worry about the installation regenerating the MySQL password. If you can pass a blank password to the Typo installation and get it configured, I'll work out the details of tweaking a di-live installation hook to do the right thing (set mysql root password to what the user chooses, update any configuration Typo configuration files accordingly).
Actually it is working perfectly now . The railsapp_user 's password will be set to random value on each installation using the scripts /usr/lib/live-installer.d/40regen-typo-secrets
