[-- Attachment #1 --] Hi, Did you copy /etc/defaults/rc.conf to /etc/rc.conf? AFAIK, the idea is to only override settings from /etc/defaults/rc.conf in /etc/rc.conf. My rc.conf is usually just 10 or 20 lines. Some network config and enabling some services. Like what you have in /etc/rc.conf.local. Regards, Ronald.
