grub-mkimage: big core.img creating

[Oleg Strikov]

Good day!
I wanna create full core.img without any additional *.mod dependencies.
I do it with:
grub-mkimage -o image [BIG MODULES LIST]
All is OK

But when i load grub2 i get something like
"modules dir not initialized"
or
"[some module function] not found"

Should i enum modules in [BIG MODULES LIST] in any special order? It seems that module try to import function from non-linked module.
Thanks
