Ill located grub files

[Arbiel Perlacremaz]

Hi every body

It happens that Grub uses some files which are not located into the grub 
directory, as in the command
if loadfont /usr/share/grub/unicode.pf2 ;
which is to be found in the 00_header section.

To my opinion, Grub has to be independant of anything else. The file 
tree used when generating the grub.cfg file may be quite different than 
the one to be used when booting. So /usr/.../unicode.pf2 may be quite 
meaningless at boot time.

If some system files are to be used by Grub, grub-mkconfig has to copy 
those files into the grub directory, and no reference outside of this 
directory should be allowed.

Best regards
