cc_bootcmd:
description: |
This module runs arbitrary commands very early in the boot process, only
slightly after a boothook would run. This is very similar to a boothook,
but more user friendly. Commands can be
specified either as lists or strings. For invocation details, see
``runcmd``.
.. note::
``bootcmd`` should only be used for things that could not be done later
in the boot process.
.. note::
When writing files, do not use ``/tmp`` dir as it races with
``systemd-tmpfiles-clean`` (LP: #1707222). Use ``/run/somedir`` instead.
.. warning::
Use of ``INSTANCE_ID`` variable within this module is deprecated.
Use :ref:`jinja templates<user_data_formats-jinja>` with
:ref:`v1.instance_id<v1_instance_id>` instead.
