Any contribution is more than welcome! Specially when we can increase 
the number of Linux distributions Kimchi runs well! =)

This library has a lot of useful functions that we can use here.

Check some of them: loadproc, reloadproc, statusproc, killproc, 
check_script_status, print_status,

Maybe use killproc() function and avoiding using 'kill -9' ? =)
