Yah.  Right now we have two schemes.

We haven't tested it much yet.

I would prefer if the library reduction script wasn't part of
boot-floppies at all.  After all, it's really a generic function and
should be probably packaged on it's own. 

Also, boot-floppies is going away after Woody and debian-installer may
have need of it as much as we do (not sure).
