grub-mkrescue vs grub-mkstandalone.

[Hongyi Zhao]

Hi here,

I have some puzzles on the difference between grub-mkrescue and
grub-mkstandalone, more specifically, I would like to know the
following things:

1. Currently, I'm using the following command to make a standalone EFI
bootloader:

$ grub-mkstandalone -O x86_64-efi -o grubx64.efi --modules='lvm fat
ntfs part_msdos part_gpt ext2 btrfs probe regexp search configfile'
boot/grub/grub.cfg=./boot/grub/grub.cfg

Can I use the grub-mkrescue to achieve the same goal?

2. In the above command, if I use all available modules as the value
of --modules, as shown below:

$ grub-mkstandalone -O x86_64-efi -o grubx64.efi --modules='time

But the EFI file generated this way will freeze when I try to load it.
Any more hints for this problem?

3. Can I achieve the same goal with grub-mkrescue to create an EFI
file as done by grub-mkstandalone?

Zhao
