The features file can have statements like this:
<configfile finalname="/etc/com.foo.cfg"
override="true">mvn:com.confignuration/myrpoject/${project.version}/cfg/com.foo</configfile>
<configfile finalname="/etc/com.bar.cfg"
override="true">mvn:comconfiguration/myproect/${project.version}/cfg/com.bar</configfile>
....etc....
That's off the top of my head so take it with a grain of salt for syntax.
When you run the features install it will overwrite the files in the etc
directory with the ones in the maven bundle which have now been updated. So
instead of modifying configuration files in the etc directory you modifying
them in your Maven configuration project and recompile the bundle and then
pull it from the repo
in order to update the values.
But you can still modify them in the etc if you wanted. You just have to
make sure you have the cm properties set to reload.
<cm:property-placeholder persistent-id="com.foo" update-strategy="reload">
