Uwe, I just got back from a site and noticed a few things regarding NBD_SWAP and the ltsp-client-setup script that lives in /etc/init.d in the chroot. I have no idea if this is related, but it *does* hang the server (and bootup of clients) when NBD_SWAP = True, the chroot is updated with hardy-updates (which fixes the NBD port bug and gets it going in the first place) at:
--- Setting up LTSP client... Negotiation: --- Upon looking in 'top' on the server, there are a few 'dd' processes running, which I assume are creating swap files in /tmp on the server. I'm not sure though. Here's my IRC log, just to give more information (Thanks Ryan for the help btw, you nailed a syntax bug in the script): http://lns.wikidot.com/randomnotes Whoever takes care of the ltsp-client-setup script should probably fix that quote issue. Possibly our whole issue with NBD_SWAP lies in this script as well... ? Cheers, Jordan Uwe Geercken wrote: > hello friends, > > I have a similar problem. I have re-installed the server.
