With regard to NFS breaking your boot process, I have run into the same 
thing recently, but it was my fault. Your screenshot omits the 
potentially-interesting information, if the problem is the same. In my 
case, /etc/rc.d/* was out of sync with /etc/network.subr. 
/etc/rc.d/netif, which handles the ifconfig_* lines in rc.conf, has 
references to an ifn_start() function in /etc/network.subr, so 
interfaces configured in rc.conf never came up.
