The GRUB configuration in /etc/default/grub sometimes change to an unexpected syntax.

The expected syntax is:

GRUB_CMDLINE_LINUX="console=tty0 (...)"

On Equinix Metal - often after redeploying a server - the syntax will be:

export GRUB_CMDLINE_LINUX='console=tty0 (...)'

This causes errors when BMRA is trying to update the GRUB settings.

Scripts will be updated to correct this in case the syntax has changed.
