Ok, let's drop this option then

The way I read the busybox source, it looks for CONSOLE= first then

static void console_init(void)
        if ((s = getenv("CONSOLE")) != NULL || (s = getenv("console")) != NULL) {
            safe_strncpy(console, s, sizeof(console));

I don't really understand how kernel command line options become env
vars though - is something preventing console= from being an env var
at this point?

dann frazier
