Under which circumstances might a GConf2 post-install scriptlet like this fail to create application's default settings unreproducibly? export GCONF_CONFIG_SOURCE="$(gconftool-2 --get-default-source)" gconftool-2 --makefile-install-rule /etc/gconf/schemas/celestia.schemas &>/dev/null || : If after package installation, the application's GConf2 defaults cannot be found in /etc/gconf/gconf.xml.defaults/, is that an indication that the post-install scriptlet was not executed at all (and e.g. Yum could be involved) or that only GConf2 failed somehow? Theories, anyone? -- Background: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143318
