What aill break when updating the mysql root users PW

==== Required information ====
- iRedMail version: 1.6
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): mysql

So far the only application that I've determined to be utilizing the initial iRedmail mysql root password is the backup cron:
/var/vmail/backup/backup_mysql.sh

Is there anything else utilizing the the mysql root password that I need to be worried about?
