 Actually, I don't think this is a good idea: we're asking the user to configure
a static device table which is not going to be used anyway.

 I think it's better to move /dev/null and /dev/console to device_table.txt -
i.e., include them in every rootfs. It just increases the size with a few
hundred bytes, it doesn't hurt because devtmpfs is normally automounted over it
right away, and it is better for the cpio/initramfs case because you won't get
the 'Unable to open initial console' message anymore (I think). Plus, the
redirects can be removed from fs/cpio/init since they'll be automatic.

 What do the other developers think?

 Regards,
 Arnout
