One piece of information that setup requests is the name and IP address for adminhost. In /etc/exports, adminhost is granted root access to / so that it can access and modify the configuration files in /etc. All other NFS clients are granted access only to /home. If no adminhost is specified, then all clients are granted root access to /. This is not recommended for sites where security is a concern.
If an adminhost is specified, then an additional line is added to the /etc/hosts file to point the default mailhost to the adminhost. This is used by the autosupport daemon (see na_autosupport(8)) to send email notification.
If a default gateway is provided to setup, it will be used in /etc/rc to specify a default route (see na_route(1)), and will also be used as the first entry in /etc/dgateways.
The hostname that is provided to setup is used to construct default names for all of the configured network interfaces. Ethernet interfaces are given names hostname-0, hostname-1, and so on. The FDDI interfaces are named hostname-f0, hostname-f1, and so on, and the ATM interfaces are named hostname-a0, hostname-a1, and so on.
