It does not work for me, that is why I reported this! The system does not boot
unless I manually add `insmod lvm` in `grub.cfg` because Grub does not find
the partition that contains the store.

So I agree something has to be done there.

As I understand it, this just means that Grub 2 has a module for reading LVM
devices and a module for reading RAID devices. But it still has to load them
somehow (unless there is a way to include them statically so they are
available from the beginning).
