On boot, the system will extract the OS image into memory and +mount the appropriate live-rw sub-directories to provide persistent storage +system configuration. + +This process allows for a system to always boot to a known working state, as +the OS image is fixed and non-persistent. It also allows for multiple releases +of VyOS to be installed on the same storage device.

Each image has a unique copy + of its configuration. + +If you have access to the console, there is a another way to select +your booting image: reboot and use the GRUB menu at startup. -- cgit v1.2.3
