Let us back up this with actual quotes from the Standard (fsstnd, I don't
have FHS around here), so we can answer questions later:

"An implementation is fully compatible with this standard if every file
 or directory which it contains can be found by looking in the location
 specified here and will be found with the contents as specified here,
 even if that is not the primary or physical location of the file or
 directory in question."

The last sentence wins.

"The implementation must, when it attempts to
 find any files or directories which are not part of it, do so in the
 location specified in this standard, though it may also attempt to find
 it in other (non-standard) locations."

Well, we are probably breaking this in a subtle way (for example by looking
into /include instead /usr/include, but with the /include -> /usr/inlcude we
would have won again). But mostly we will comply to this.

Mmmmh. Reading a standard, I can't find this. Why does it "breaks policy"?
The standard says nothing about /bin and /usr/bin carrying the same file,
(or the same for /lib). This seems to be unspecified.

You can bet on it :) But I think this is the reason why it says nothing
about /bin/foo and /usr/bin/foo. Maybe we need an addition to the Debian
Polic document later (but first we need a GNU Hurd file system standard).
