scripts in chkconfig are they called parallel or one after the other ?

the scripts in chkconfig will they be executed in order , for example this has 5 scripts I mena chkconfig --list returns 5 scripts .
if script 2 is taking very long time will it wait till script 2 is completed before starting script 3 ? or it will start all the scripts in parallel ?

They get started in a specific order, but run in parallel. The order of starting is often a requirement to allow dependencies to be resolved. For instance, the network must be up and running before network servers and clients can be started. Most things that get started in the init.d directory are daemon processes that run perpetually.
On most distros, you can watch the startup system list the processes and the status as they are launched.

There is a way to control that kind of stuff. (Put in a script manually a while ago.) But that way differs depending on your distro (on OpenSUSE they do it somewhat differently than on Debian based distros). If you're on something Debian-like, you will probably find a "README" and a "skeleton" file in /etc/init.d. There's a lot of reading up (also using google, of course) to do, but if you want to add a script it's the way to do it. Only then you'll be sure to have done it the way your particular script needed it.
