VyOS provides several kernel command-line options to modify the normal boot
|
|
process.
|
|
To add an option, select the desired image in the GRUB menu at load time.
|
|
Type **e** to edit the first line, then type **Ctrl+X** to boot.

Specify custom config file
|
|
==========================
|
|
|
|
You can use a configuration file instead of the default ``/config/config.boot``
|
|
file.
|
|
If the specified file doesn't exist or isn't readable, the system uses the
|
|
default configuration file.
|
|
No additional verification is performed, so specify a valid configuration file.
|
|
|
|
.. code-block:: none
|
|
|
|
vyos-config=/path/to/file
|
|
|
|
To load the *factory default* configuration, use:
|
|
|
|
.. code-block:: none
|
|
|
|
vyos-config=/opt/vyatta/etc/config.boot.default
|
|
|
|
|
|
Disable specific boot process steps
|
|
===================================
|
|
|
|
These options disable certain steps in the boot process. Understand the
|
|
:ref:`boot process <boot-steps>` before using them.
