Hi Peter, Please note that script is a copy of an internal xcat postscript. The link I posted points to the specific line on which we made a change (modified the regexp for grep). Note also that if you find you need that modification, you must be careful how you install the modified script. Since xCAT provides the original script, if you just replace the xCAT provided one, you will lose the customization at the next xCAT upgrade. Our current solution is to put the custom script into /install/postscripts/custom, then symlink the original file to the custom one. An xCAT upgrade will break the symlink, but at least you won't lose the change. The "setup.sh" script in that repo will recreate the symlink (among other things). Finally, note that isn't the case on all Dell systems and I don't recall which ones. --Andy
