+Subject: [PATCH] system: add reboot method to system ubus object
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Sometimes, for various reasons, user may want to reboot a device. This
+is a common task and it makes sense to support it with something common
+like a procd.
+
+Right now both: LuCI and LuCI2 implement this feature on their own with
+luci-rpc-luci2-system reboot and luci-rpc-sys reboot. This leads to code
+duplication and situation may become even worse with more software
+controlling system with ubus.
+
+Othen than that procd already has support for rebooting so one may
+consider this ubus method even cleaner.
+
+Once we get this patch in place we may consider switching LuCI and LuCI2
+to this new method.
