Bc packages almost always contain more than a single file, would be good to have a place where to keep track of all the files installed by various packages. For example: we create a dir at /etc/fpkg/; there, we will have configs etc, but also a subdir 'packages'; in this subdir, there will be a directory with the package name, which will hold a file named `fileslist` or sth, where on each line there will be the full path to the installed files from this package. I think this will make removal cleaner. Also, the package dir can hold other things like metadata.
