We want to know, with what configuration (version of the image) each node was booted.
Hence, we keep image definition files and postscripts in CVS. During image generation we create file /etc/IMGVERSION and fill it with CVS "$Id$" of files with image definition (.pkglist, .exlist, .repolist, .postinstall). Then, during boot, each "CVS enabled" postscript adds one line to /etc/IMGVERSION. Then you can determine in any time what image you are running and what postscipts in which versions were run. /etc/IMGVERSION cat look like:
smbec02n001(smbec02b01n01):~ #cat /etc/IMGVERSION
