"man nodename" says it best...

"When a machine is standalone or its IP address is configured
locally, the /etc/nodename file contains the system name. By
convention, the system name is  the  same  as  the  hostname
associated with the IP address of the primary network inter-
face, for example, hostname.hme0.

If the machine's network configuration is delivered  by  the
RPC bootparams protocol, the /etc/nodename file is not used,
as the system name is delivered by the remote service.

Given a system name value, regardless of source,  the  uname
utility invoked with the -S option is used to set the system
name of the running system.

If the machine's network configuration is delivered  by  the
DHCP  protocol,  the  /etc/nodename file is used only if the
DHCP server does not provide a value for the Hostname option
(DHCP standard option code 12).

A system name configured in /etc/nodename should  be  unique
within  the  system's name service domain in order to ensure
that any  network  services  provided  by  the  system  will
operate correctly."

greetings,

Stoyan
