Full disk encryption for multiple disks

I have set up this kind of arrangement by encrypting an LVM setup. Then
you have just a single passphrase to enter, and everything unlocks.

I can't remember what I had to do to set up this arrangement. It might
have been with the alternate installer. The laptop I have this
arrangement on is on 12.04.

I agree that it would be nice if the installer could do this. Though
most users just have one disk, so there shouldn't be any problem in the
common case.

It comes down to limited developer resources, as always. Patches are
always welcome, subject to any design constraints in the installer (of
which I'm unaware).

The next Ubuntu release seems unlikely even if somebody did implement
this, as the next release is an LTS release and the focus is on
stability. In any case, feature freeze is less than three weeks away.
