[PATCH] Install to LVM PVs

[Dryden Personalis]

I updated this guy's patch to work with 2.02 beta 2, at least.

I've just worked on the version that gets downloaded and unpacked on 
Kubuntu / Ubuntu 16.04.

One part of the patch didn't apply because apparently some tabs have 
entered a file, namely grub-core/disk/lvm.c.

Another part didn't apply because code had been refactored from 
grub-setup.c to setup.c.

I've only compiled with these extra packages:

- bison
- flex
- libdevmapper-dev

and automake was also required. I've had to symlink the 1.15 executables 
to 1.14.


I'm not sure why the patch never made it into mainline grub, but back 
then (2013) the argument was that it was doing something to an area that 
was not meant for that.

However LVM contains the --bootloaderareasize flag that seems to be 
meant for this, and if you put it to 2048 sectors (or 1M) it ought to 
work cq. just works.

ie. pvcreate --bootloaderareasize 2048s /dev/sda, followed by, 
grub-install /dev/sda, will just work and result in a bootable system 
from that harddisk.

I don't know if I can attach here, and I don't know what will happen 
with tabs if I inline it.

So I will attach first.

Regards.


ps. I did not test booting from the harddisk to a system on the 
harddisk, but it boots a system on another device just fine, so I see no 
reason why it wouldn't work.
