Disk config with GRUB/EFI, RAID + LVM

[Rémy Dernat]

Ok, FYI, I think I have a working configuration with :

```
# example of new config file for setup-storage
#
# <type> <mountpoint> <size>   <fs type> <mount options> <misc
options>

disk_config disk1 disklabel:gpt fstabkey:uuid bootable:1
primary - 2G - -
primary /boot/efi 1G vfat rw createopts="-F32"
primary swap 2G swap sw,pri=1
primary - 0- - -

#disk_config disk2 sameas:disk1
disk_config disk2 disklabel:gpt fstabkey:uuid
primary - 2G - -
primary /boot/efi2 1G vfat rw createopts="-F32"
primary swap 2G swap sw,pri=1
primary - 0- - -

disk_config raid fstabkey:uuid
#raid1 /boot disk1.1,disk2.1 - - mdcreateopts="--verbose
--metadata=1.0" createopts="-L boot"
raid1 /boot disk1.1,disk2.1 vfat rw,noatime mdcreateopts="--verbose
--metadata=0.90"
raid1 - disk1.4,disk2.4 - -

disk_config lvm fstabkey:uuid
vg vg_system md1
vg_system-root / 60G-200G ext4 rw,noatime
vg_system-tmp /tmp 20G-50G ext2 rw,noatime,nosuid,nodev
##vg_system-scratch /scratch 30%- ext2 rw,noatime
vg_system-home /home 30%- ext4 rw,noatime,nosuid,nodev
```

My previous message was crystal clear. md0 did not have any formatted
filesystem on it. So I added `vfat` option on /boot.

Best regards,
Rémy
