Really?
Past alpha 4 the package management are included in haiku. This make all files installed by hpkg virtual.
To make it possible to install old pkg files of beos they implement the non-packaged folder. All pkg file run to install are send to non-packaged automatically.
Ok you can install files by hand too, this is right.
I think it is unlucky to place this files under config, because not all placed here are config files.
You can correct me, for me the home directory in a later comming multiuser system are the boot folder of the user. Here he can install all he want without destroying the main system. So the Non-packaged beside a package folder should be in home and not config. Or a folder like Non-packaged should nsmed to user-file for example.
