Is there a command line flag that allows you to pass a config file at launch time of a PXE loaded copy of grub.efi ? This would be a grub.efi made with the makestandalone tool.
Example would be grub.efi -c http://server/that/makes/the/configfile/for/this/boot.scriptinglngextension?variables=&morevariables=<http://server/that/makes/the/configfile/for/this/boot.scriptextension?variables=&morevariables=> Thank you in advance!
