G'day Russel,

hmmm... NOw having the dynamic rules running I find that barnyard is

dynamic rules have a gen code of 3 not 1.

The aforementioned issue with dynamic rules having a generator_id of 3 
and not 1, which leads to messages not being matched correctly, does not 
exist in barnyard2.

Presumably then sid-msg.map has an implicit gen of 1.

You presume correctly.

Is it expected that these be added to the gen-msg.map?

If so it is a bit painful -- the sidmsg.map can be created from  
scratch from the rule files but the gen-msg.map has a whole lot of  
static stuff and one therefore needs to append to the original.

Is there a way of having this in a separate file?
