 I've reported a Bug against `sysvinit', with a script that calls
 `chvt' attached to it.

#!/bin/sh

# Performing a VT switch is a cheap way to reset the VGA palette.
# The boot logo uses a restricted color set; reset it to standard colors.

tty=$(tty)

# Not a serial console or pty.
if expr "$tty" : "/dev/tty[1-9]" >/dev/null; then
    if [ -f /proc/fb ]; then
	tty=${tty##/dev/tty}
	chvt 2
	chvt ${tty}
