Installing to iSCSI on SuSE Linux is quite easy:

At command line prompt just add this option:
  netsetup=1 WithISCSI=1
and you'll be prompted to enter iSCSI target IP, and you
can select one of the available targets to install to.

This has been tested on SLES (SUSE Linux Enterprise Server) 10.

<code>
option space gpxe;
option gpxe-encap-opts code 175 = encapsulate gpxe;
option gpxe.bus-id code 177 = string;
  
group {
  host iscsihost {
    hardware ethernet 00:0c:29:01:02:03;
    fixed-address iscsihost.mydomain.org;

    if not exists gpxe.bus-id {
        filename "undionly.kpxe";
    } else {
        filename="";
        option root-path "iscsi:192.168.0.10::::iqn.1987-05.com.cisco:lvol1";
    }
  }
}
</code>

But there are still some topics to investigate:

* System wants to deactivate Swap (located on iSCSI device) after network has gone down
