When you create the cluster, the machine you happen to be logged into is automatically added to the
cluster as the first machine, and also added to the Main_Group. Its machine level settings effectively get
moved to the cluster level as much as possible. There are no settings at the group level, and the only
settings left at the machine level are those which do not make sense at the cluster level, and cannot be
clustered. Examples are IP addresses, featurekeys, etc.

Leave as many settings at the cluster level as possible. If only one machine in the cluster needs a different
setting, copy that cluster setting to the machine level for that machine. Do not move that setting. If you
move a setting which has no factory default (e.g. HAT table, SMTPROUTES table, LDAP server profile,
etc.), the systems inheriting the cluster settings will have blank tables and will probably not process
email.
