Comment 15 for bug 1670336

I've been looking at this issue. The linked merge proposal for ecryptfs-utils almost gets us there. I've got a cleaned up version that I've been testing with. Unfortunately, I run into an issue in the systemd generated swap unit for the swapfile. It does something a little different for swap files than it does for swap partitions and my testing VM sometimes hangs (infinitely) during boot waiting on the swap unit to start. I still need to do more investigation to understand the problem and come up with the correct solution there.
