OK, sorry, I remember again, it wasn't you, it was Andreas. Sorry.

Actually, warnings are very difficult. Eighter chmod returns -1
and sets errno to EPERM, or it returns 0, but making chmod and
friends output anything to stdout/stderr is very tricky (found this
out the hard way when I wanted to generate debugging messages: you
get segfaults etc when you send anythign to stderr too early in the
startup of any programme).

So, as Joey also preferred this, fakeroot-0.0-8 will just default
to "--nodebian", and have the "--debian" option to change that.
