+libseat is used to get DRM master and input devices for non-root users.
+On Wayland this is only necessary when starting a compositor under KMS
+console (e.g., /dev/ttyv0 backed by /dev/dri/card0). Nested sessions like
+"Wayland on X11" or "Wayland on Wayland" don't need extra configuration.
+
+By default libseat tries to find the first working backend. To override
+set LIBSEAT_BACKEND via environ(7). Available backends and try order:
+
+* "seatd" - seatd-launch(1) or seatd rc.d(8) service
+%%BASU%%* "consolekit2" - ck-launch-session(1) or pam_ck_connector(8)
+
+"seatd" backend requires membership in "video" group to be allowed to
+use setuid bit in seatd-launch(1) or connect to seatd(1) socket.
+
+  # pw groupmod video -m <user>
+  $ exit # log out to refresh group permissions
+
+For example, to start a wlroots-based compositor replace "sway" with
+your compositor (e.g., "hikari", "wayfire", "labwc", "river") then run
+
+  $ seatd-launch sway
+
+Alternatively, configure and run seatd(1) as system service
+
+  # sysrc seatd_enable=YES
+  # service seatd start
+  $ sway
+
+%%BASU%%To use ConsoleKit2 run
+%%BASU%%
+%%BASU%%  # pkg install consolekit2 basu
+%%BASU%%  # sysrc -x seatd_enable
+%%BASU%%  # service seatd stop
+%%BASU%%  # sysrc dbus_enable=YES
+%%BASU%%  # service dbus start
+%%BASU%%  $ ck-launch-session sway
+%%BASU%%
+%%BASU%%where "ck-launch-session" can be dropped after
+%%BASU%%
+%%BASU%%  # echo "session optional pam_ck_connector.so" >>/etc/pam.d/system
+%%BASU%%  $ exit # log out to re-trigger PAM
