 +===== Partition encryption =====
 +Each user is allocated one encrypted image file that can grow to fill the free space on its disk partition. The image file is stored in a directory specific to the user using a hash of the user name with a salt value. The image itself is a sparse file that is attached to the system through a loop device. Using the device mapper subsystem, a virtual, encrypting block device, dm-crypt, is layered on top of the loop device.
