NAME

ris − remote installation services utility

SYNTAX

/etc/ris

DESCRIPTION

The ris utility is an interactive utility that performs the following remote installation services. The ris utility loads kits into the ris control directory, /usr/adm/ris, adds clients for remote installation services, and removes clients from remote installation services. 

The remote installation services use the /usr/adm/ris directory as a base. 

This directory contains the subsets of the kits that can be installed to clients on a network. This directory also contains a directory called clients, which holds individual permission files for each client.  The permission file of a specific client contains an ordered list of subsets that are allowed to be installed to that client. The ordering of the permission files is checked by the ris utility whenever a model permission file is used to create a client permission file.  The model permission files allow a system manager to set up a default network kit for a particular type of client. Through the use of model files the system manager can customize a clients network kit to either contain or omit certain subsets. This customization may be necessary for clients with small disk capacity or for clients that are not licensed for all the available kits. All model files begin with the prefix "model." in order to be distinguished from client permission files. 

The /usr/adm/ris directory also holds the instctrl directory, which is crucial to the remote installation service.  This directory contains files used to verify the contents of the individual subsets.
