retitle 582294 approx doesn't handle symlinks properly
thanks
Hi there, Eric.
Please, pardon my defficiencies of reading non-mainstream computer
languages, but, if I understood the code correctly, you completely
removed the possibility of using symlinks for the approx cache.
This broke approx 4.3 for users that maintain /var/cache/approx as a
symlink to another filesystem:

If I read it correctly, Philipp's approx cache contains symlinks that
point to the exact directories where they are, which would make these
kind of symlinks easy to deal with.
Of course, detecting if a symlink creates a directed cycle in the
filesystem is a PITA, but the case above is an easy one.
OTOH, rejecting any possibility of symlinks seems wrong in principle.
Thanks, Rogério Brito.
