+ AUTHOR: markj@FreeBSD.org
+
+ The snmpd and snmptrapd daemons now drop privileges by default when started
+ using the rc scripts provided in the package. Make sure that snmpd
+ configuration in /usr/local/share/snmp is readable by the "snmpd" user. If
+ you have defined extension scripts in snmpd.conf, make sure that they can be
+ executed by an unprivileged user. To revert to the old behavior of always
+ running as root, set snmpd_sugid="NO" or snmptrapd_sugid="NO" in /etc/rc.conf.
+
+ See the snmpd rc script for a hint on how to debug any permission problems
+ that might arise as a result of this change.
