Syncing Options for Computer Lab Machines?

sirfunk asks: "I'm going to begin helping out maintaining the computer labs around my university campus. I was wondering what solutions the Slashdot community had hints and tips for maintaining computer lab networks. We need a solution where we can keep a remote image on a server, and the computers will update to that on bootup. We also need them to be able to update, even if Windows is severely messed up (so if Windows dies, just reboot it). I know there's commercial solutions like Deep Freeze, but I was hoping someone knew of a creative Open Source alternative. I'd love if we could run these as dumb terminals with *nix, however that won't be an option for the general public. One Idea I had was to make the machines boot into a Linux partition that would rsync a FAT filesystem (the update) and then reboot to that FAT filesystem. The whole thing about getting it to boot into Linux first and then Windows next might be tricky. I would love to hear everyone's ideas on this topic. If you have any ideas that would run cross-platform (Mac/Windows) that would be great, too."

OS X Server

[Johnny Mnemonic]

This probably won't be able to apply to you, but it's worth knowing: Mac OS X Server can do this out of the box (to Mac clients). Apple calls it "NetBoot", and it's been available since at least 2000; I believe the tech came from NeXT originally.

Under OS 9 and 10.3 it allows for clients-without-drives as they get all their OS etc from the server down the wire (10.1, .2 required a HD, but only for swap), which is useful in some secure installations. Read more about it here.
