One more point: I have to identify a virtual disk or partition to use cgd.
When doing so I have to decide its size up front and reserve that much
space, even if I may not need that today. And when that space fills, I am
not sure whether there ways to expand the FS easily. Even if there are,
encfs/cryfs are lot more convenient here as they piggyback on native FS in
user space and do not really require setting aside space for them.
