    Back with Suse 7.3 or 8 I had a simple system going,
     all machines NFS mounted /var/lib/YaST/... off a central server.

    Whichever machine needed it first actually downloaded each patch
     and all subsequent machines simply found it already available.
    It all looked the same as YOU ran
     but the download phase happened almost instantly.

    Then Suse went to YaST2 and changed the location.
    I never bothered to find out where the patches were kept.
    Till now.
    It looks as if /var/lib/YaST2/you/mnt/ is a good mount point.
    Under that a fairly familiar tree branches out
      .../i386/update/8.2/rpm, patches and scripts

    Having found that out, I'll re-instate this on the cluster.

    But at home, I've been using the house squid to cache downloads.

    At home a network joins all computers to a Suse-server
     with a shared ADSL connection, which runs a squid web cache.
    Configure this into YaST:Network Services:Proxy as a URL
    ( for me this is: HTTP: http://brennan.localdomain:3128
                                    FTP: http://brennan.localdomain:3128
    )
     and yast will use the squid

    It will cache all downloads and re-supply them at 100 Meg.
    Messier as we will end up with 3 copies of the patch,
     1 in the squid cache, 1 in the workstation and 1 in the server's patch dir.
    Also depending on the squid's settings,
     it may not cache it (too big) or may dump it for lack of space.

    There's 2 more methods...
