Michael Prokop 29ae7d2112 TT#105407 Ensure lvm2 is present before grub-install is executed

grub-pc >=2.04-11 has a new behavior regarding /boot/grub/i386-pc/
handling, where we end up with an empty /boot/grub/i386-pc/ after
*successful* grub-install execution:

| root@grml ~ # vgchange -ay
| 3 logical volume(s) in volume group "ngcp" now active
| root@grml ~ # mount /dev/mapper/ngcp-root /mnt
| root@grml ~ # grml-chroot /mnt /bin/bash
| Writing /etc/debian_chroot ...
| (spce)root@grml:/# cd
| (spce)root@grml:~# grub-install /dev/sda
| Installing for i386-pc platform.
| Installation finished. No error reported.
| (spce)root@grml:~# ls -la /boot/grub/i386-pc/
| total 16
| drwxr-xr-x 2 root root 12288 Dec 16 12:04 .
| drwxr-xr-x 4 root root  4096 Dec 16 12:07 ..

This causes the installed system to fail to boot with:

| GRUB loading..
| Welcome to GRUB!
|
| error: file `/boot/grub/i386-pc/normal.mod' not found.
| grub rescue> _

The underlying issue is that recent grub versions unlink the files
inside /boot/grub/i386-pc, though it doesn't report anything about it
(even under `--verbose` execution).

This is triggered in our situation, as lvm2's vgs binary isn't present
yet. In earlier versions of grub this wasn't causing any problems and
grub-install happily installed the files inside /boot/grub/i386-pc, even
though we installed lvm2 only afterwards via our metapackages.  To
ensure lvm2 is available during installation time within
grml-debootstrap, explicitly add to it list of packages to be installed.

details regarding the grub bug.
