* src/utils/ecryptfs-setup-private: LP: #1328689 - fix a long standing bug, where setting up an encrypted private, encrypted home, or migrating to an encrypted home did not work correctly over ssh sessions - the root cause of the bug is some complexity in the handling of user keyrings and session keyrings - the long term solution would be to correctly use session keyrings - the short term solution is to continue linking user and session keyrings
