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

grub2-script-check does not check the syntax of grub commands. In the example provided, password_pbkdf2 is missing an argument:

# grep -B3 -A3 superusers /boot/grub2/grub.cfg
if [ -f ${prefix}/user.cfg ]; then
  source ${prefix}/user.cfg
  if [ -n "${GRUB2_PASSWORD}" ]; then
    set superusers="test"
export superusers
    password_pbkdf2 "test"
  fi
fi

Causing grub2 to error during boot:

error: ../../grub-core/commands/password_pdkdf2.c:94:two arguments expected

grub2-script-check does not report any error, it considers the configuration file to be okay.

What is the impact of this issue to you?

Can't-boot issues even after checking the configuration file.

Please provide the package NVR for which the bug is seen:

grub2-tools-2.06-114.el9_7.x86_64
