Here you go:
$ mkdir small-clone
$ cd small-clone
$ git init
# Tell git to fetch only master (AKA head) and stable/8 branches
$ git remote add -t master -t stable/8 origin
git://git.freebsd.your.org/freebsd.git
$ git fetch origin # fetches about 1.6M objects

Practically it does not save you all that much on repo size or the
time to fetch stuff. Complete clone is ~700M/1.9M objects and
head+stable/8 clone is only about 10% smaller. If you really want to
have smaller repo you will need to trip repo history. I'm not sure yet
how to do that.
