There is always good reasons to change it at one time or another, none of these say it is a bad idea to set it early though. In general I see 3 categories of machine: - diskless machines that needs to get the hostname from DHCP as they have no local configuration storage whatsoever - personal, un-managed machines that can change name on a whim. - managed machines, that may have keytabs and can never change name but use things like dynDNS instead to tell other machines where they are.
