I only use Ubunty Edgy on my laptop at the moment and I had a hard time doing LVM in that installer; I set all the LVM up afterwards. Note that putting / on LVM requires you to use an initrd with the devicemapper and LVM support in it. You may have to regenerate your initrd for that to work. Personally I don't put / on LVM because it makes life more difficult than the advantages are worth. With everything else (/usr, /var, /tmp, /home and so on) in their own LVs, root can be very small and little need to resize it. Adalbert, I’m not sure if Feisty’s installer would let you set that up.

So, that cuts it down to one command to do it all! Can't find it using Google, but I know it exists, that's how I extended my Xen array about 6 months ago!
