Hi,
    Is there any way to obtain the path info from which a standalone
grub.efi was launched. In case of grub-mkimage uisng --prefix="" results in
prefix being set to the dir from which the efi app was launched, but in the
standalone grub.efi the prefix is (memdisk)/boot/grub . In
(memdisk)/boot/grub/grub.cfg I added a search and configfile option that
points to the external grub.cfg (in <UEFISYS>/efi/grub/grub.cfg), but I
don't want to hardcode the grub.cfg file path in the configfile command in
the memdisk grub.cfg.

Is it possible to introduce a env var within grub2 (independent of prefix)
which gives the path (grub style) from which the grub.efi file was launched
by the firmware, so that I can do "configfile
(path_from_which_grub.efi_loaded)/grub.cfg" in (memdisk)/boot/grub/grub.cfg
in the standalone file. I want the standalone file to be be portable, no
hardcoding of path of external grub.cfg file (which is editable by the
user). Thanks in advance.

Regards.

Keshav
