What I would do is find a small/simple existing script in init.d and 
copy & modify it to run your script with the start argument and do 
nothing with the stop one. On my Debian box the ntpdate init.d script is 
pretty simple - I've pasted it in below.

Then in order for it to be executed you need a file in 
rc<default-run-level>.d. If you don't know the default run level it 
should be in /etc/inittab. cd into rc3.d (or whichever is appropriate) 
and do something line

ln -s ../init.d/capture S99capture

if capture were the name of the script you'd created. on the link, the S 
means it's a start script so it's executed when the system goes into 
that runlevel. (The ones starting with K are run when you go out of that 
level, like when you shutdown). The number indicates the order in which 
to run the scripts - 99 implies do it after everything else just in case 
it needs something else to be running already. Oh, make sure the init.d 
script has execute permission.

Cheers,

Martin
