logind: flip KillUserProcesses to on by default
This ensures that users sessions are properly cleaned up after. The admin can still enable or disable linger for specific users to allow them to run processes after they log out. Doing that through the user session is much cleaner and provides better control. dbus daemon can now be run in the user session (with --enable-user-session, added in 1.10.2), and most distributions opted to pick this configuration. In the normal case it makes a lot of sense to kill remaining processes. The exception is stuff like screen and tmux. But it's easy enough to work around, a simple example was added to the man page in previous commit. In the long run those services should integrate with the systemd users session on their own. https://bugs.freedesktop.org/show_bug.cgi?id=94508 https://github.com/systemd/systemd/issues/2900

+ * systemd-logind will now by default terminate user processes that are
+ part of the user session scope unit (session-XX.scope) when the user
+ logs out. This behaviour is controlled by the
+ KillUserProcesses=yes|no setting in logind.conf, and previous default
+ of "no" is now changed to "yes". This means that user sessions will
+ be properly cleaned up after, but additional steps are necessary to
+ allow intentionally long-running processes to survive logout.
+
+ While the user is logged in at least once, user@.service is running,
+ and any service that should survive the end of any individual login
+ session can be started at a user service or scope using systemd-run.
+ systemd-run(1) man page has been extended with an example which
+ shows how to run screen in a scope unit underneath user@.service.
+ The same command works for tmux.
+
+ After the user logs out of all sessions, user@.service will be
+ terminated too, by default, unless the user has "lingering" enabled.
+ To effectively allow users to run long-term tasks even if they are
+ logged out, lingering must be enabled for them. See loginctl(1)
+ for details.
* The unified cgroup hierarchy added in Linux 4.5 is now supported.
Use systemd.unified_cgroup_hierarchy=1 on the kernel command line
