Question regarding the regionservers file on the HBase master

I've got 2 questions regarding the regionservers file that is placed on 
the HBase master:

1. In Section 128.3 of the docs 
(http://hbase.apache.org/book.html#adding.new.node), it says "If you 
rely on ssh to start your daemons, don’t forget to add the new hostname 
in /conf/regionservers/ on the master." What does this really mean?

2. What is the regionservers file used for? Why can't the HBase master 
and Slaves discover each other through the zookeeper /hbase/rs znode?
