Background
==========
Currently the nodename configuration is stored in the /etc/nodename file.

During installation, the installer will prompt the user for the nodename and 
save the configuration into the /etc/nodename file.  When the system boots up, 
if the system is standalone or the IP address is configured locally, the 
/etc/nodename file contains the system name.  Users can modify the file 
/etc/nodename to change the hostname for a standalone system or if the IP 
address is configured locally.  In such a case the change will take effect 
at next boot.

Problem Statement
=================
Update the svc:/system/identity:node SMF service which will take care of 
setting the nodename of the  system installed by means of the Installer
technologies.  Furthermore, update various components that currently reference 
/etc/nodename to use the new mechanism, namely cvcd, setuname, metaset and 
nodename(4) for nodename.

Requirement
===========
The nodename will be configurable via SMF property of svc:/system/identity:node
SMF service. 

Proposal
========
1. Add the nodename property to the svc:/system/identity:node SMF service.
   The property definition (config/nodename) will be added in the SMF manifest.
   Update the identity-node method to use the new property.

2. RBAC for nodename access to include solaris.smf.manage.nodename as the 
   authorization and with a profile description of "Node Name Management".

3. Update the various Caiman installers to use the new property.

4. Obsolete file /etc/nodename. This file will no longer exist in the system

5. Modify existing /etc/nodename consumers, so that they operate on the SMF
   property instead of the file. The following consumers were found in 
   the ON gate:

       cvcd
       setuname
       metaset

   Other consolidations will receive a flag day announcement and be given 2 
   builds prior to the removal of the nodename file.

6. Update appropriate man pages:

       nodename(4)
       metaset(1M)

7. Make appropriate announcements in a Patch release of Solaris and to internal
   development aliases.
