CONFIG_NULL_TTY_DEFAULT_CONSOLE: Support for console on ttynull

General informations

The Linux kernel configuration item CONFIG_NULL_TTY_DEFAULT_CONSOLE:

• prompt: Support for console on ttynull
• type: bool
• depends on: CONFIG_NULL_TTY = CONFIG_y && ! CONFIG_VT_CONSOLE
• defined in drivers/tty/Kconfig
• found in Linux kernels: 6.15-rc+HEAD

Help text

Say Y here if you want the NULL TTY to be used as a /dev/console device by default.

For example, it might be useful to prevent a VT-less kernel from writing the system log to a random device connected to the serial port.

Another console driver still might get preferred via the command line, SPCR, or the device tree.

If unsure, say N.
