This is *not* a FreeBSD-style rc script. It simply switches on "$1" for the word start or stop and performs that action. It does *not* use /etc/rc.subr to determine whether snmpd has been enabled. As a result, snmpd will be started during boot on any machine where the port net-mgmt/net-snmp4 is installed. Some would consider this to be a security problem. >How-To-Repeat: >Fix: I've included a patch that creates a FreeBSD-style rc script in files and updates the port to install it.
