@ -68,7 +68,34 @@ Accordingly, the following priority ranges can be used for custom deploy steps:
1 to 19
Any steps that are run when the user instance is already running.
.. note:: Priorities 60 to 99 are currently reserved and should not be used.
Direct deploy
^^^^^^^^^^^^^
The :ref:`direct-deploy` interface splits the ``deploy.deploy`` step into:
``deploy.deploy`` (priority 100)
In this step the node is booted using a provisioning image.
``deploy.write_image`` (priority 80)
A combination of an out-of-band and in-band step that downloads and writes
the image to the node. The step is executed asynchronously by the ramdisk.
``deploy.prepare_instance_boot`` (priority 60)
In this step the boot device is configured and the bootloader is installed.
Additional priority ranges can be used for custom deploy steps:
81 to 99
In-band deploy steps to run before the image is written.
61 to 79
In-band deploy steps to run after the image is written but before the
bootloader is installed.
Other deploy interfaces
^^^^^^^^^^^^^^^^^^^^^^^
Priorities 60 to 99 are currently reserved and should not be used.

The ``deploy`` deploy step of the ``direct`` deploy interface has been
split into three deploy steps:
* ``deploy`` itself (priority 100) boots the deploy ramdisk
* ``write_image`` (priority 80) downloads the user image from inside
the ramdisk and writes it to the disk.
* ``prepare_instance_boot`` (priority 60) prepares the boot device and
writes the bootloader (if needed).
Priorities 81 to 99 to be used for in-band deploy steps that run before
the image is written. Priorities 61 to 79 can be used for in-band deploy
steps that modify the written image before the bootloader is installed.
