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. #cat /dev/null > $installroot/etc/IMGVERSION #for ext in pkglist exlist postinstall repolist; do # [ -r $workdir/$profile.$ext ] && cat $workdir/$profile.$ext | grep -E '^[[:space:]]*#.*[[:space:]]\$Id' >> $installroot/etc/IMGVERSION #done
