What were you trying to do that didn't work?

When using Image Builder to create an azure image, /etc/default/grub is not created with the required entries from our documentation. Below is what /etc/default/grub is showing as on the servers:

GRUB_CMDLINE_LINUX="ro crashkernel=auto console=tty1 console=ttyS0 earlyprintk=ttyS0 rootdelay=300"
GRUB_TIMEOUT=10
GRUB_ENABLE_BLSCFG=true
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
GRUB_TERMINAL_INPUT="serial console"
GRUB_TERMINAL_OUTPUT="serial console"
GRUB_DEFAULT=saved

When compared to the entries detailed in

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/deploying_rhel_8_on_microsoft_azure/assembly_deploying-a-rhel-image-as-a-virtual-machine-on-microsoft-azure_cloud-content-azure#making-configuration-changes_configure-the-image-azure

there are some that are missing or slightly off. Primarily the GRUB_TIMEOUT_STYLE=countdown line

Please provide the package NVR for which bug is seen:

Expected results

The default grub should match our documentation on whats expected

Actual results

Additional configuration is needed. This either needs to be automatic, or documented that additional steps are needed. Preferably automatic.
