Whole disk encryption

[Dale Amon]

Just did a test drive on Quantal, tried several different
types of build. However the one thing I could not figure
out was how to get multiple partitions on the encrypted
disk. It does not seem to want to allow me to specify the
size of the / partition either to allow me to build a
separately keyed LUKS partition for other uses or to do
so via LVM.

Did I miss something in the install menu's? It does not seem
like an unusual requirement.
