Console code will need serious work anyway; note that current names do _not_ refer to tty devices - there is some overlap, but right now we have * console drivers * some of them being connected with tty drivers; those can tell which tty driver corresponds to them * console ouput code maintaining chain of console drivers; output is sent to them, attempt to open() /dev/console ends up picking the first console driver that has corresponding tty one (== has console->device()) and opening the tty device in question * unholy mess with redirects.
There's no device nodes for console drivers. So names in console=... are something very odd, indeed. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
