So, talking of carp, what is the best way to change things like
metrics live?

I really don't want to programmatically rewrite my master bird.conf.
Being able to #include another file, which did a #define would be
really useful for things like this. Then I could just change the
file concerned (or better make it a symlink to a master or a slave
version)
