LVM support

[jjfam1]

LVM needs read-write access to /etc/lvm in install media

FIX:
mount -t tmpfs tmpfs /etc/lvm

grub2 installs /dev/mapper/vgname-root instead of device MBR /dev/vda
do not let installer write to logical volume and write to device

FIX:

bind mount proc, dev, and sys so grub can find partitions and install
mount -o bind /proc /mnt/proc
mount -o bind /sys /mnt/sys
mount -o bind /dev /mnt/dev

actually put the grub2 binaries on the filesystem and install to MBR
cd /mnt && tar xf /var/cache/lunar/grub2*
cd /
chroot /mnt
grub-install /dev/vda

create initramfs and add entry for grub
grub-mkconfig > /boot/grub/grub.cfg

mkinitrd /boot/initramfs-3.11.4.img 3.11.4

edit files to allow booting as initrd is not in grub.cfg

It's possible with a few manual steps through the "exit to shell" function within the installer to achieve all of the above. However we intend to add a LVM editor in the installer. This is a long term goal for the next major release.
