If CONFIG_NULL_TTY_CONSOLE is enabled, and CONFIG_VT is disabled, ttynull will become the default primary console device, based on the load order. Users and distributions that are migrating away from CONFIG_VT will benefit from this as /dev/console would not suddenly become /dev/ttyS0 which could otherwise cause some user space behavior changes, namely the TCGETS ioctl failing, which causes libc's isatty() to incorrectly return false when /dev/ttyS0 is disabled, and will prevent a device that is connected to a user's /dev/ttyS0 to suddenly start getting kernel log messages.
