Ok, attached.

Run it as root:

perl ./eacces.pl --nonempty --logfile logfile [--allow_other] /usr/local

It makes a bind mount of /usr/local to /tmp/original.$$ then uses fuse 
to redirect all access to /usr/local to that bind mount.  If you don't 
give the "allow_other" option anybody but root will get EACCES.

It's just a hacked version of the "loopback.pl" script from the Perl 
Fuse package (libfuse-perl)
