The network is gigabit core with 100MB to each PC. At present the LTSP clients just run a shell, no X window. They basically run the kernel in memory and the remaining parts of the setup come from an NFS share to the LTSP server. However, that share is mainly just to send/receive grid jobs which run in memory (we use the 'Condor' package to handle the grid side of things). The linux grid does nothing but run grid jobs, there are no 'users' as such. Our LTSP server acts as the PXE server as well, but DHCP is done via a Windows box. However, since it points DHCP'ing clients to the PXE server it shouldn't require any change (as it all works at present). >From what you have said though it seems that adding a new package to the LTSP server either automatically installs it into the relevant parts necesary for LTSP, or it is necessary to re-install it using something else which will install it correctly for LTSP. Either way it is easier than at present where I need to rebuild things from source :-) Secondly, as far as I remember ubuntu LTSP uses a 2.6 kernel, whereas our 4.1 LTSP uses a 2.4 kernel. This can be a problem, if our users create a job dependant on a 2.6 library, then it may well not run on a 2.4 kernel (i.e. the current grid). When I manage to get some hardware together I'll see about trying all this out.
