--- Comment #60 from Dr. Werner Fink
From man:pam_systemd(8)
pam_systemd - Register user sessions in the systemd login manager that is without pam_systemd.so there is no login session service anymore: pam_systemd registers user sessions with the systemd login manager systemd-logind.service(8), and hence the systemd control group hierarchy. On login, this module ensures the following: 1. If it does not exist yet, the user runtime directory /run/user/$USER is created and its ownership changed to the user that is logging in. 2. The $XDG_SESSION_ID environment variable is initialized. If auditing is available and pam_loginuid.so run before this module (which is highly recommended), the variable is initialized from the auditing session id (/proc/self/sessionid). Otherwise an independent session counter is used. 3. A new systemd scope unit is created for the session. If this is the first concurrent session of the user, an implicit slice below user.slice is automatically created and the scope placed in it. In instance of the system service user@.service which runs the systemd user manager instance. On logout, this module ensures the following: 1. If this is enabled, all processes of the session are terminated. If the last concurrent session of a user ends, his user systemd instance will be terminated too, and so will the user's slice unit. 2. If the last concurrent session of a user ends, the $XDG_RUNTIME_DIR directory and all its contents are removed, too. -- You are receiving this mail because: You are on the CC list for the bug.
