Title:
  Systemd User Service Cannot Start with ECryptFS Due to PAM
  Misconfiguration

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  If a user encrypts their home directory using the standard Ubuntu
  installer GUI, which uses ecryptfs, then the users home directory is
  encrypted while systemd is trying to start their user services so they
  cant be read. After consulting with the systemd developers, the
  problem is remarkably simple to fix

  Ubuntu releases /etc/pam.d/common-session with the follow entries:

  session optional        pam_systemd.so
  session optional        pam_ecryptfs.so unwrap

  they need to be swapped to

  session optional        pam_ecryptfs.so unwrap
  session optional        pam_systemd.so

  so that decryption happens before systemd user services are started.

  https://lists.freedesktop.org/archives/systemd-
  devel/2018-January/040301.html for further information
