The startup mechanism runs the installed startup modules at the end of the [[boot process|BootMechanism]].

! Startup Modules
|
||
|
|
|
||
|
|
Modules with their ''module-type'' field set to `startup`:
|
||
|
|
|
||
|
|
* Must expose a `startup` function
|
||
|
|
** For synchronous startup modules the startup function is called as `startup()`, asynchronous modules are passed a callback they must invoke on completion: `startup(callback)`
|
||
|
|
* May expose a `name` property that is used to identify the task
|
||
|
|
* May expose a `dependencies` property containing an array of names of dependent tasks that must be run before this one

! Startup Processing
|
||
|
|
|
||
|
|
The startup mechanism begins by sequentially executing the tasks that have no dependencies. It then continues executing tasks as they are unlocked by the completion of their dependencies.
|
||
|
|
|
||
|
|
There is no guarantee of the execution order of tasks that share the same dependencies.

||

|
! Startup Tasks
|
||
|
|
|
||
|
|
The core defines the following sequence of named startup tasks:
