README for pam_xdg
PAM module that handles the XDG Base Directory Specification[1]
directories, including creation of XDG_RUNTIME_DIR and injection
of according environment variables into user sessions.
For it to work it must be included in /etc/pam.d -- to make it a
vivid part of session handling the file /etc/pam.d/common-session
seems best. Include the following early:
session optional pam_xdg.so [notroot] [runtime] [track_sessions]
Use notroot argument to only handle XDG for non-root users.
Use runtime argument to only handle of XDG_RUNTIME_DIR.
Use track_sessions to remove XDG_RUNTIME_DIR once the last user
session ends (take care of CAVEATS of manual, maybe).
