Available only on Sun 386i systems running a SunOS 4.0.x release or earlier. Not a SunOS 4.1 release feature.
The /etc/systems file is used only by SNAP and Automatic System Installation, and contains basic information about each host on the network. It is an ASCII file in the /etc directory on the Network Information Service (NIS) master server. To successfully administer all systems in a NIS domain using SNAP, there must be an entry in this file for each host listed in the /etc/hosts file. For each host, this file contains a one-line entry, of the following form, where each field must be separated by a TAB character:
system architecture sunos "hostid" memory_size disk_size network_role
Here is a sample systems file:
vulcan s386 sunos4.0.1 "12345678" 8000 327000 master_bootserver polaris s386 sunos4.0.1 "" 8000 91000 slave_bootserver star sun4 sunos4.1 "" 8000 91000 network_client traveler s386 sunos4.0.1 "" 8000 0 diskless_client

Take precautions to lock the /etc/systems file against simultaneous changes if it will be edited with a text editor; editing with vipw.8 provides the necessary locking.
The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed. The name Yellow Pages is a registered trademark in the United Kingdom of British Telecommunications plc, and may not be used without permission.
