From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
Some time ago a trivial patch broke HPPFS (one var became a pointer, not
all uses were updated). It wasn't fixed at that time because not very
used, now it's been requested so I've fixed this, and it has been tested
positively (at least partially).

You only need this if you are setting up a UML honeypot. Otherwise,
