hppfs (honeypot procfs) was an attempt to use UML as honeypot.
It was never stable nor in heavy use.
As Al Viro and Christoph Hellwig pointed some major issues out
it is better to let it die.

- tristate "HoneyPot ProcFS"
- depends on PROC_FS
- help
- hppfs (HoneyPot ProcFS) is a filesystem which allows UML /proc
- entries to be overridden, removed, or fabricated from the host.
- Its purpose is to allow a UML to appear to be a physical machine
- by removing or changing anything in /proc which gives away the
- identity of a UML.
-
- See <http://user-mode-linux.sf.net/old/hppfs.html> for more information.
-
- You only need this if you are setting up a UML honeypot. Otherwise,
- it is safe to say 'N' here.
