Installing Ubuntu on LVM
From the Live CD, run:
sudo apt-get install lvm2 sudo vgchange -ay
Then, install Ubuntu the standard way. Once finished, do the following:
sudo mount /dev/mapper/[LVM root] /mnt sudo mount -o bind /dev /mnt/dev sudo mount -o bind /proc /mnt/proc sudo mount -o bind /mnt /mnt/mnt sudo mount /dev/[boot partition] /mnt/boot sudo chroot /mnt
This gives you a shell within the new system. We need to set up LVM here:
sudo apt-get install lvm2 sudo update-initramfs -k all -u
