I am using debian-sys-maint as practical way to do database dumps in our debian systems, somenthing like this:
mysqldump -u debian-sys-maint -p`cat /etc/mysql/debian.cnf | grep password | tail -n 1 | cut -d' ' -f3`
I would like to know if there is a similar user to this in CentOS, I just need the user to be able to make backups. This way I don't have to create a new user on every system. The interesting part of this is that /etc/mysql/debian.cnf contains the clear password for the debian-sys-maint.
