It looks like this might help where different images need different postscript functionality. We certainly don't find value in the OS and ARCH attributes. We currently code all of the necessary choices into the profile name which is just a subdirectory name (including a datestamp). I either use "chdef node profile=compute-gpfs-ge-20130207" or "nodeset netboot=centos6-x86_64-compute-gpfs-ge-20130207". I never directly manipulate any of the other image related tables. After building our image on a separate build system I rsync the rootimg and initrd image to the xCAT system and just do the nodeset command (and reboot). This new functionality needs proper documentation, not just how to change from the old method. Even better would be good documentation on workflows where nodes can have multiple generations of of images (datestamps) or alternate versions (production vs test image and historic rollback capability).
