you need to write a script for /etc/init.d that takes an argument 
"stop", "start", and optionally "restart" and/or "reload".

this script can either call that bamboo.sh script or just contain a copy 
of it as the 'start' part (I'd go with the latter if its really simple)

do remember, you have to set up any environment this process may needmay 

Take a look at /etc/init.d/smartd  as an example init script, as this is 
a fairly simple one.

your script should have a comment on top something like...

    # bamboo       Starts the bamboo service
    # chkconfig:   345 05 95
    # description:   blahblah blahdablah blah
    # ....

the important line there is chkconfig:   whihc in this case says, by 
default you want this service run at run levels 3,4,5, and it is to be 
started at priority 05 and stopped at priority 95
(lower means sooner ni the order of things)

after putting that script in /etc/init.d, then...

    service bamboo {start|stop}

will manuallly start/stop this service, and

    chkconfig bamboo on

and that will configure it to run at startup per those chkconfig options.
