- Should I just do iSCSI backed diskless setups? Probably doesn't scale well.
What's wrong with NFS? You can even have root on NFS these days A quick google found: http://www.digitalpeer.com/id/linuxnfs
My first thought: Install a workstation as normal, then tar/untar them onto the NFS server. With some correct seperation of files you should be able to share most of the filesystem between machines (eg /usr could be readonly). You might even be able to make root readonly, but I've never tried that.
