This is a *weird* corner you've stumbled upon. The flag is indeed used
by ceph-deploy and that hasn't changed in a while. However, as you
point out, there is no trace of that flag anywhere! I can't find where
is that defined at all.
Running the latest version of ceph-deploy + ceph, that flag *does* work for me.
What version of ceph are you using?
