+#-- Example of booted image versioning
+#-- 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 (see /install/postscripts/cvs_template.sh and /install/postscripts/cvs_template.pl) 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.

Then you can determine in any time what image you are running and what postscipts in which versions were run.
