I agree.  You can either simply #ifdef-out the Libalias glue code in ipfw 
on LIBALIAS or introduce a new option "FIREWALL_NO_ALIAS" or something to 
have that effect.  The first would not break POLA and should be 
preferred - IMO.  Having the module build default to "with LIBALIAS" is 
okay to make this great feature available from a default installation, 
but there certainly should be a way to disable it on a custom build.  
Also a make.conf switch to disable it from the module could make sense.
