This config adds all files under /foo because they match to regex /foo, which is equivalent to /foo.* . What you probably want is:
This appears to be self contradictory. The first line gave me the impression that =/tmp is the same as =/tmp$ and therefore the $ symbol wouldn't be needed. However, this isn't the case.
