-* logind: maybe watch utmp asynchronously using inotify, and populate our own

-  now, all "ssh" sessions will be tracked without their TTY by logind (which is
-  not just unfriendly to users as this means "loginctl session-status" shows
-  less information than "who" in many cases, but also breaks the IdleAction
-  logic, as we never can detect such sessions as idle, as we have no TTY to
-  watch). ssh sets the PAM_TTY field on its PAM sessions to "ssh" rather than
-  the actual pty, because the PAM session is opened early on for new
-  connections, but the PTY only registered much later (if at all). ssh writes
-  the utmp record only after a TTY is actually registered, hence we could use
-  this data then, and use it if it is available. Using utmp for this is ugly of
-  course, and watching things asynchronously even more so, but it should be
-  good enough for the idle detection logic at least.
