Yup, that's the pattern.

For example, after committing HADOOP-11565, my startup looks like this:

{code}
$ hadoop --slaves version | grep repo
$ hdfs namenode -format
$ hdfs --daemon start namenode
$ hdfs --slaves --daemon start datanode
$ yarn --daemon start resourcemanager
$ yarn --daemon start proxyserver
$ yarn --slaves --daemon start nodemanager
{code}

Of course, you can do fancier things now that all of the -- options are supported on slaves....
(i.e., yarn --slaves --hosts="proxyhost" --daemon start --config /my/customfig --debug proxyserver
will start the proxyserver on the host proxyhost with the custom config in debug mode.)

I need to fix sbin/(start|stop) yet, but they'll turn into wrappers around these commands,
eliminating about 4 levels of shell indirection vs. branch-2...
