Public bug reported: after updating /etc/default/grub and running update-grub or update-grub2 the changes do not do anything.
The settings changed are: GRUB_DEFAULT="0" GRUB_TIMEOUT="0" GRUB_HIDDEN_TIMEOUT="0" GRUB_HIDDEN_TIMEOUT_QUIET=true I have mucked about with the settings above and they seem to do nothing to /boot/grub/grub.cfg When I change the 30 second timeout there after reboot I do see a change. So it seems that the config generator is not working properly?
