No, config_directory is unset when grub executes the configuration file
pointed to by core.img. There is no config_directory listed by the "set"
command (using|grub-mkconfig (GRUB) 2.02~beta2-9ubuntu1.4|).
It seems to only be set by the configfile command.

I cannot always use prefix as I want to access the scripts located in
the same directory as the current configuration file. This is the reason
why I would be glad to always use config_directory, which is
unfortunately unset when the current configuration file is the one
core.img points to.
