Virtual Terminal support is also disabled as no terminal devices are supported and enabled. Disabling CONFIG_VT (removing the no longer needed override for CONFIG_VGA_CONSOLE) reduces the kernel image size by about 65 KB. This default configuration remains suitable for a system using an initramfs cpio file linked into the kernel image.
