Scenarion A, desktop
  - / on non-LVM, fixed size, as recovery from a broken LVM setup is way
	harder if / is on LVM
  - /usr on LVM, as it can grow significantly, and having it on LVM is
	much more flexible

Scenario B, laptop/netbook
  - / non-encrypted, small, asks for passphrase to boot
  - everything else on dm-crypt+lvm

This seems a very weird proposition to me. Separate /usr works, as is
more flexible: needed space for / is < 500MB, needed space for /usr is >
