Just a little ;)

As long as the maguc type is based on the content of the file, it works
rather well. As we don't need a full classification, but only for those fies
we actually will execute, there will hardly be confusion about this.

That's a nice idea. Where we are at it, we should also store the package
information for a file, so we don't have an external database
(var/lib/dpkg/info) for this. It would also speed up the dpkg -S command
;)

You say a magic type database is a hack, and on the other hand file
exetensions are a better indicator? Phew. Microsoft uses file extension
(".tgz file" if it can't recognize). I think examining the content is a
much better strategy.

Mmh. I like to think of the file utility as the standard reference. I didn't
knew about any other such databases. That apache uses file extensions is
bad, but it's reasonable for a browser which only serves a well defined set
of files.

Yep. For this and other stuff (package managment) a filesystem which can
store arbitrary metadata would be nice.
