In /etc/rc.conf:

   ifconfig_em0="SYNCDHCP"

dhclient runs on startup, then later tries to run again:

   Starting dhclient.
   em0: no link ...
   .
   .
   got link
   (...)
   Starting Network: lo0 em0.
   (...)
   Starting devd.
   Starting ums0 moused
   .
   dhclient already running? (pid=344).
   Creating and/or trimming log files

So is this from /etc/network.subr starting dhclient because the 
interface is set to DHCP, then /etc/rc.d/dhclient running directly 
later?
