From a6e74fd03c93ec9cdb31570b9a6b676aef4ee4c5 Mon Sep 17 00:00:00 2001
From: Matthias Hentges <oe@hentges.net>
Date: Sun, 23 Apr 2006 14:47:58 +0000
Subject: altboot: - Removed multiple die() functions - Altboot no longer
 activates an off-flash altboot-menu when not   booting from flash - Added a
 debug_echo function which is disabled in non-rc and   non-snapshot builds -
 RC's and snapshots now spawn a debug shell on tty4 right after   the kernel
 is booted - die() messages are now colored red/white, debug is
 purple(?)/white - Fixed start_networking() on collie and made it a little bit
 more verbose
