Remote Boot of a Diskless Linux Client for Operating System Integrity

摘要

These instructions describe how to build a diskless client with dedicated user store on the server. The diskless Linux client is organized to provide read-write files over NFS at home, read-only files over NFS for accessing bulky immutable utilities, and sone volatile RAM disk files to allow the Linux Kernel to boot. This approach is exceptional because 1) the client system is diskless; system administration is managed at a single server, and 2) it is more secure; the only data that can be modified is user data under the home directory. Although these instructions describe setup between a Linux client and a Linux server, the Linux client can boot from any server with BOOTP, TFTP and NFS services installed.
