I briefly looked in there. This is the same script it uses to start MySQL, and was
installed with the rpm of MySQL.
I would think it should come with all available options already...
To me, it doesn't look like it even reads that option from the my.cnf file. It doesn't
look like its reading any option from mysqld_safe group.
Pasting the whole thing, so I don't have to work with file attaching.
