DESCRIPTION

14       systemd-logind is a system service that manages user logins. It is
15       responsible for:
16
17       ·   Keeping track of users and sessions, their processes and their idle
18           state. This is implemented by allocating a systemd slice unit for
19           each user below user.slice, and a scope unit below it for each
20           concurrent session of a user. Also, a per-user service manager is
21           started as system service instance of user@.service for each logged
22           in user.
23
24       ·   Generating and managing session IDs. If auditing is available and
25           an audit session ID is already set for a session, then this ID is
26           reused as the session ID. Otherwise, an independent session counter
27           is used.
28
29       ·   Providing polkit[1]-based access for users for operations such as
30           system shutdown or sleep
31
32       ·   Implementing a shutdown/sleep inhibition logic for applications
33
34       ·   Handling of power/sleep hardware keys
35
36       ·   Multi-seat management
37
38       ·   Session switch management
39
40       ·   Device access management for users
41
42       ·   Automatic spawning of text logins (gettys) on virtual console
43           activation and user runtime directory management
44
45       User sessions are registered with logind via the pam_systemd(8) PAM
46       module.

52       as users, sessions and seats.

55       APIs systemd-logind provides.
