Bug#697450: grub-common: insmod part_gpt included twice

[Laurens Blankers]

Package: grub-common
Version: 1.99-23.1
Severity: minor

Dear Maintainer,

When installing GRUB on a disk with GUID partition table (GPT) the 
entry for loading the support module appears twice. This does
not cause any problems, not even an error message, but I wanted
to report it in case this issues masks a bigger issue.

Sniplet from /boot/grub/grub.conf:
-- BEGIN --
        insmod gzio
        insmod raid
        insmod mdraid1x
        insmod part_gpt
        insmod part_gpt
        insmod ext2
-- END --

The problem appears to be in /usr/share/grub/grub-mkconfig_lib in 
the function prepare_grub_to_access_device.

Sincerely,

Laurens
