shadowfs is a concept for yet another translator, which will allow to "mount"
several file systems on top of each other, transparently. So, if /dev/hd1s1
contains a file foo, /dev/hd1s2 contains a file bar, both files will be seen
in the same directory (the root directory of the common "mount" point).
Several options will allow to fine tune the behaviour (which partition will
be written to for which files etc).

Na, we don't use this _too_ often. One thing we explain with shadowfs is the
lack of a real /usr on the Hurd. At other points we mention shadowfs when we
feel that shadwfs could be useful in such a situation.

It's not really vague, the concept is so simply that it doesn't require much
explanation. But I will add something to the FAQ about it.

Nobody wrote it.

Lack of time?

Yes, definitely. Also, the current development focusses on stabilization and
bug fixing. There are other things we urgently need which probably have a
higher priority. However, every developer works on what he feels is most
important right now, and shadowfs just seems to not be on thetop of the list
