mysqld_safe and pid files


hello monty et al

i'm trying to write an init script for maria and artix, which is using openrc

I got it to start up but the pid-file is a problem and I think that the 
command line options for mysqld_safe is not working.  it doesnt 
create the specified pid file

[www3 ~]# /usr/bin/mysqld_safe --pid-file=/run/mariadb.pid
