I just did brew install --devel riak to get riak 2.0.1 on my OSX machine. After that I started a node with:
/usr/local/Cellar/riak/2.0.1/bin/riak start
What I see in ps ax is that it's using some /usr/local/Cellar/riak/2.0.1/libexec/data/generated.configs/vm.2014.10.03.11.27.37.args config:
➜ ~ ps ax | grep riak

As I understand, what I'd like to have is to use /usr/local/Cellar/riak/2.0.1/libexec/etc/riak.conf config, which is much more like good old /etc/riak.conf from linux.
What should I do to use it? Thanks!
The key word there is generated. The script that starts Riak takes the riak.conf file. It converts that from the dotted format that is nice for people to edit, to the app.config and vm.args format that erlang wants to read. It then merges it with any advanced.config file that may be there, and writes it to generated.configs, and has erlang use that. Even on linux, it doesn't use riak.conf directly, but rather a generated config based on it.
If you want the why and how, take a look at the cuttlefish repo
