Async boot scripts doc clarification

[Overdrivr]

With multiple asynchronous boot scripts, is the server waiting for the first boot script (using alphabetical order) to call back before starting the next boot script ? Or is starting all of them at once, and waits for all to call back ?

I believe this is not documented, and IMO it could be an improvement to add it.

I believe it states that in this part:
https://docs.strongloop.com/display/public/LB/Defining+boot+scripts#Definingbootscripts-Asynchronousbootscripts

You must call the callback function when the script is finished to pass control back to the application.
so as per your question this is the answer: is the server waiting for the first boot script (using alphabetical order) to call back before starting the next boot script

@crandmck Any improvements to the wording we can make in the docs?

Boot scripts are processed alphabetically, one at a time (not in parallel) -- this applies to both sync and async boot scripts.

pass the control back to the application

Is not very clear IMO. Your sentence @superkhau in the contrary is ideal, clarifies anything without doubts.

Boot scripts are processed alphabetically, one at a time (not in parallel) -- this applies to both sync and async boot scripts

Clarified in http://loopback.io/doc/en/lb2/Defining-boot-scripts.html#boot-script-loading-order.
Thanks!
