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 #-- $Id: base.pkglist,v 1.4 2008/09/02 15:40:12 sikorsky Exp $ #-- $Id: base.exlist,v 1.3 2008/09/02 14:57:08 sikorsky Exp $ #-- $Id: base.postinstall,v 1.21 2008/09/04 12:05:45 sikorsky Exp $ #-- $Id: base.repolist,v 1.3 2008/09/02 14:57:08 sikorsky Exp $ $Id: syslog,v 1.2 2008/09/02 14:54:29 sikorsky Exp $ $Id: remoteshell,v 1.2 2008/09/02 14:54:29 sikorsky Exp $ $Id: sa_set_net,v 1.5 2008/09/04 11:32:07 gdasstm Exp $ $Id: sa_gpfs,v 1.4 2008/09/02 17:30:05 sikorsky Exp $ git-svn-id: https://svn.code.sf.net/p/xcat/code/xcat-core/trunk@2137 8638fb3e-16cb-4fca-ae20-7b5d299a9bcd
