Diskless Booting For the Modern Age
An anonymous reader writes "Ever wonder what happened to PXE? Intel's popular standard for diskless booting hasn't been updated since 1999, and has missed out on such revolutions as wireless Ethernet, cloud computing, and iSCSI. An open source project called Etherboot has been trying to drag PXE into the 21st century. One of their programmers explains how to set up diskless booting for your cloud, using copy-on-write to save space."
It wasn't designed for it - PXE boots without authentication on the client so that the hardware gets the image thinly and then auth takes place when the OS is installed. It assumes control of the local LAN is in place and it is trusted. If you are looking for auth at this level you'd need to look at authentication to the switch or wireless on the network - pre-authentication using something like 802.1X. I'm not 100% clear but I believe gPXE has something that probably covers that in the docs as it has scripting capability pre-receiving DHCP addresses (at the level for wireless authentication and possibly 802.1X)...
