Thanks for making hibernation work and for bringing that up. I have two
questions:

  1. Does hibernation work in case of swap-partition inside an
     luks-encrypted device?

  2. Does hibernation work in case of a swap-file inside a
     root-partition inside a luks-encrypted device?

Also, I'm not sure if it makes sense to mark the hibernation-feature
stable and finished if the mentioned two cases are not supported.
