Word of advice, also recompile anything that staticly uses the libalias library.
natd specifically is one I missed which broke my system after reboot.

ipfw2 tool was built, new alias library was built but natd compiles in libalias
as a static, hence although my firewall rules loaded, everything through natd
broke (including DNS lookups which 'broke' the rest of the startup)

I resolved this by adding 'IPFW2=YES' to /etc/make.conf
