Symlinks don't clean anything up, they complicate things rather,
even though it isn't clear from experience on platforms like NetBSD.
In particular, some FreeBSD tools (e.g. pax that is actively promoted by
POSIX and pkgsrc) behave subtly differently in presense of symlinks.
Please, don't introduce them here. At least not until consequences are
well understood.

There is clear mechanism, even though it isn't documented.
It works well enough to me.
