Comment 3 for bug 1098360

I checked the init script in galera repo and it is still

MYADMIN="/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf"

Now, since this is a cluster environment, it doesn't make sense
to have different passwords for different boxes.

However, not providing the config file imples that, like
RHEL/CentOS, the root password is empty or provided in the cnf
file, otherwise the init will fail again.

Another possibility is to ignore the replication of mysql.users
table and run dpkg reconfigure after every SST. But this can get
complicated.
