A debootstrap of trusty created an /etc/default/grub with

GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10

which resulted in the warning mentioned, but also caused grub to not automatically boot the default menuentry after 10 seconds. It just hung around forever waiting for a manual selection. Especially not good for headless servers.

At the time of testing, my grub version was 2.02~beta2-6
