An OS server is a system type. When you choose the OS server system type during installation, you are prompted to allocate disk space for its diskless clients.
When an OS server is installed over the network rather than interactively, the Host Manager records that it is an OS server.
Choose the OS server system type during installation, and configure disk space for diskless clients.
The workstation must have disk space for clients. When partitioning the disks, provide at least 30MB disk space per client in /export/root, and 24MB of swap space per client in /export/swap.
