"If you find yourself needing to run a certain command or series of commands each
time you start your Linux system, you can often automate the process by editing the
local init script, usually located at /etc/rc.d/rc.local or somewhere

your system boots into multiuser mode. If it's a directory, any scripts that you create
there will be run during boot."
