+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!
+
+.. glossary::
+
+    no-vyos-migrate
+      Do not perform config migration.
+
+    no-vyos-firewall
+      Do not initialize default firewall chains, renders any firewall configuration unusable.
