Well, slow machines should be used as Thin Clients, or dumped. > > Thin-client-server - basically a combination of workstation, Terminal > > server and a boot-server > > For the large setups some of you aim at, I'd recommend the possibility > to setup a pool of application servers different from boot servers. > Or how well do Skolelinux setup multiple DHCP servers on same subnet? Jonas, have you actually looked at what SKolelinux are ? No, we dont set up multiple DHCP-server on the same subnet, we uses one dhcp-server on the backbone, and one for each of the thin client network, and let the one application-server for each of the thin-client network act as application-servers. > > Lessdisks - Something quite similar to LTSP, but uses debian packages > [cut] > > I have estimated somewhere between > > 200-400 hours to get a working solution with debian-edu. > Using Vagrant's 0.6.x or the package in Debian? This estimate was in august , with what was availible then, Now with Vagrant's 0.6.x package the estimate is maybe a bot more accurate, around 270-300, but not including the 50+ hours I have, already put in to the project. > > FAI - well here I'm blank.
