/etc/motd is overwritten now anytime a system administrator edits the file. /etc/motd is currently a sym link to /var/run/motd. Currently way things work, /etc/motd.template is used along with a freebsd header everytime service motd restart is run or a reboot occurs, effectively killing anything added to /etc/motd. A fix would be "rm /etc/motd; ln -s /etc/motd.template /etc/motd" There is no reason for /etc/motd to do a useless symlink to /var/run/motd just for changes to be overwritten, when it would be way better if the link was made to /etc/motd.template instead so the system administrators changes are not lost between reboots etc.
