In the typical (or ideal) case, these processes all originate -from a single common ancestor. - - -As an implementation detail, for now, this secret should be stored in -the process environment by the session leader under the name -XDG_SESSION_COOKIE. When and if we are able to take advantage of a -mechanism in the underlying system to store session registration -information - we will. However, such a mechanism is not known at the -present time. - - -Using an environment variable does have certain advantages. For one, -it is quite easy for a process to opt-out of a Session by simply -unsetting the XDG_SESSION_COOKIE variable. - - -Limitations of using an environment variable implementation include -not being able to strictly limit visibility of the secret to a particular -process ancestry. So, it is not possible to enforce session boundaries -other than on a per-user basis. For example, we don't yet have a way -to prevent a process from moving between sessions owned by the same -user. - - - - - Session leader - -The session leader is the process that requests that a new session be -opened. It does this by connecting to the D-Bus system bus and using -either org.freedesktop.ConsoleKit.Manager.OpenSession() or -org.freedesktop.ConsoleKit.Manager.OpenSessionWithParameters(). The session -that it registers will remain open until the connection to the system -bus is lost or it calls org.freedesktop.ConsoleKit.Manager.CloseSession(). - - -The session leader is the only process for which CloseSession() will -be allowed. - - - - - Seat - -A seat is a collection of sessions and a set of hardware (usually at -least a keyboard and mouse). Only one session may be active on a -seat at a time. - - -At the present time, all Sessions that are considered "local" to -a system will be added the the first Seat and every other Session -will be added to its own Seat. - - -True, hardware, multi-seat capabilities will be added in a later release. - - - - -- cgit
