+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.

+
+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!

+USB
+===
+
+In the past serial interface have been defined as ttySx and ttyUSBx where x was
+an instance number of the serial interface. It was discovered that from system
+boot to system boot the mapping of USB based serial interfaces will differ,
+depending which driver was loaded first by the operating system. This will become
+rather painful if you not only have serial interfaces for a console server
+connected but in addition also a serial backed :ref:`wwan-interface`.
+
+To overcome this issue and the fact that in almost 50% of all cheap USB to serial
+converters there is no serial number programmed, the USB to serial interface is
+now directly identified by the USB root bridge and bus it connects to. This
+somehow mimics the new network interface definitions we see in recend Linux
+distributions.
+
+For additional details you can refer to https://phabricator.vyos.net/T2490.
