VyOS has several kernel command line options to modify the normal boot
|
|
process.
|
|
To add an option, select the desired image in GRUB menu at load
|
|
time, press **e**, edit the first line, and press **Ctrl-x** to boot when

ready.

Specify custom config file
|
|
==========================
|
|
|
|
Tells the system to use specified file instead of ``/config/config.boot``.
|
|
If specified file does not exist or is not readable, fall back to
|
|
default config. No additional verification is performed, so make sure
|
|
you specify a valid config file.
|
|
|
|
.. code-block:: none
|
|
|
|
vyos-config=/path/to/file
|
|
|
|
To load the *factory default* config, use:
|
|
|
|
.. code-block:: none
|
|
|
|
vyos-config=/opt/vyatta/etc/config.boot.default
|
|
|
|
|
|
Disable specific boot process steps
|
|
===================================
|
|
|
|
These options disable some boot steps. Make sure you understand the
|
|
:ref:`boot process <boot-steps>` well before using them!
