Running a script automatically on system boot?

["Zach Uram" <netrek@gmail.com>]

Hello,

I installed the darktstat package in Debian lenny/sid and want to know
the canonical way to set it up so that every time there is a reboot of
my server it will run "/etc/init.d/darkstat start" automatically?
Please be very specific, I've never done this before. Running kernel
2.6.18

Regards,
Zach
