This is just an option. Just creating a symlink into stow is enough.

That's exactly what it does. Perhaps we're misunderstanding about
what I meant to be copying, so I'll be more explicit and make some
example.
The stowfs actually works like this:
# settrans /bin /hurd/unionfs -m bin --stow=/stow
(imagine this for all meaning directories like /lib, eventually /etc, et cetera)
This makes /bin (and the others) to be handled by the stowfs. To be accurate,
/bin will contains all files (and eventually subdirectories) contained in
/stow/*/bin (a thread automatically updates entries when removing or adding
new entries in the /stow directory).
This is exactly what was discussed in this mailing list, and I guess
it's what your
idea of stowfs was about. Am I right?
Now, by "copying" I meant to do something like this:
# cp /packages/emacs-21 /stow
that is, to _copy_ the package into /stow (that is, having a real directory
into /stow instead of making a symlink). This was only the main way I used to
test the stowfs support (is more interesting on a debugging POV since files
are more slowly added into the union and I could test better the support for
dynamic insertion of directories). _BUT_ symlink are supported too, that is we
_can_ install emacs into the system just by doing:
# ln -s /packages/emacs-21 /stow/
So I am not talking about copying things to /bin, I was just talking
about the ways
to modify the /stow dir.
Hope this clarifies everything,
Gianluca
