After this message, you will be given a shell with ${DEVICE} mounted on "/target". You may work on it using the tools available in the installer environment. If you want to make it your root file system temporarily, run "chroot /target". If you need any other file systems (such as a separate "/usr"), you will have to mount those yourself.
