Public bug reported: Binary package hint: grub-common
The default settings for /etc/default/grub won't allow the machine to boot through automatically to the default OS -- someone must hit <Enter> on the console, which is almost never an appropriate configuration for a server. Here is the default /etc/default/grub: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT="2" GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" with just a bit of trial and error I discovered that a non-zero value must be set for GRUB_HIDDEN_TIMEOUT in order for the machine to boot through to the first OS after timeout; e.g. # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=1 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT="2" GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" Looking over the documentation for grub2, it seems clear that GRUB_HIDDEN_TIMEOUT shouldn't have anything to do with whether or not the machine boots through after timeout. I'm guessing this is a grub2 bug?
