The old text was simply wrong, we used to read $layout from /etc/kernel/install.conf and the machine ID from $KERNEL_INSTALL_MACHINE_ID from /etc/machine-info. Correct that. Apparently KERNEL_INSTALL_MACHINE_ID was already known back in v235 times, hence don't mention it anymore. it's kinda weird retro-fixing these NEWS entries, given we deprecate them again, but I couldn't let this really incorrect stuff be.
