During final processing, the ConfigInstaller runs which installs the cars 
associated with the selected packs into the config-store. The ConfigInstaller 
reads var/config/configure.xml to determine which cars need to be installed.
Configure.xml is created by the assembly plugin, but contains
variables to be replaced at install time to inform ConfigInstaller
of which cars need to be installed.

I fixed this with the patch on GERONIMO-1518.  Originally,
I had missed the dependency in project.xml and the files
were not copied to target.

Interesting question. There are some interesting options here.

1. If one uses the installer in default mode, the situation mentioned will 
occur. For instance, if javamail is not selected, then it will not be 
installed and the easiest remedy is a reinstall.

2. If, however, one uses the -Dadvancedmode=true mode of the
the installer, then it's possible to install the configuration, but have
it inactive at runtime. It'll be in the config, but not running in the server.
Of course, with item #1, it's possible to install everything and disable
unwanted items in config.xml manually and achieve the same goal.

3. There's actually a third option that's not exposed well (yet?). One
might install everything with the advanced installer then delete everything
in config-store, modify configure.xml, run ConfigInstaller to get 
a new configuration and modify config.xml accordingly.  Of course, this
would be for very advanced folks.

1518 accomplishes this.
