Headless Stretch server waits at grub menu

#1 Post by zntrx »

I have headless stretch server running configured for serial & console input/output.

When booted/rebooted it waits at the grub menu for input rather than booting after the specified timeout. If I insert a CR over a serial link it boots fine.

Any suggestions as to what I'm doing wrong?

/etc/default/grub as follows

Code: Select all

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi=force intel_iommu=on"
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8"
GRUB_TERMINAL="console serial"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
GRUB_DISABLE_OS_PROBER="true"
