Hi again, Martin Pitt has started to solve the problems with cryptswap for 'Encrypted home'. Maybe our activities made a difference, but I think a complication with systemd made the situation acute, and created a need for at least a simple fix: See post #39 and following in this bug report https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/953875 'This is a lot worse now that systemd actually complains about the missing device and blocks the boot on it for 90s.'
