+# Normally shutdown and reboot should always go through DSME.
+#
+# Running reboot/poweroff/etc binaries directly bypasses DSME
+# and the shutdown does not work the same way as powering off
+# via UI. The differences include for example:
+# - Emergency calls/alarms/charger/etc are not considered
+# - Applications do not get save-data and pre-shutdown signals
+# - Shutdown vibration, led and logo do not get triggered
+#
+# Use shell functions to allow users to continue using familiar
+# commands from interactive shell, but do the shutdown/reboot
+# via dsme.
+#
+# If needed, the real systemd binaries (e.g. reboot) can still
+# be invoked by using the full path:
+# # /usr/sbin/reboot
+#
+# Or by ignoring the shell functions via command:
+# # command reboot
+
+# Define shell functions for interactive shells only
