Drop the dependency on DBD:MySQL
To simplify the installation requirements of mylvmbackup, the dependency on DBD::MySQL should be removed. It's only required to issue the following commands "FLUSH TABLES WITH READ LOCK", "UNLOCK TABLES" and "SHOW MASTER/SLAVE STATUS". These could potentially also be issued by calling the regular "mysql" command line client and reading the output from there.

Whiteboard
Whomever posted this clearly doesn't understand how backups and locking work in MySQL. You cannot use the `mysql` command line to accomplish this task. Once the connection to mysql has terminated, all locks are released. So, once you issue the command `mysql -uroot -pmypass -e "FLUSH TABLES WITH READ LOCK"` the tables, are flushed and locked but immediately released because the command completed and returned you to shell.
