Daemon that monitors the pressing of the back panel reset button to either
"The entry under the Administration->Management allows you to turn this daemon off. The daemon just watches the reset button reboots or resets the router depending on how long it is held down."
If this daemon is disabled you can still reboot the router by either power cycling it, or running the reboot command via telnet, SSH, or the administration screen. If your router is used on a location where the reset button is unaccesible, disabling this daemon will free some resources on the router.
