Talk:Symlink Applications

This article says "The same effect can be had by modifying /etc/palm/luna.conf..." But this is unclear. WHAT effect, exactly? Surely doing that doesn't actually move an application onto the media partition, as the rest of the article describes. Does it cause new apps to be installed there? Does it it enable you to (through a separate step) move an app there without leaving a symlink? Or something else? Please elaborate.
