[olug] Interesting kernel module

[Rob Townley]

Reminds me of this popular Sundtek USB TV card for Linux that
indirectly modifies System binaries because the author says it is
needed to get it to work.  He preloads his driver into all the
binaries on the system replacing open(), close(), and many other major
basic functions.

You really gotta read Andrew Tridgell's "worst abuse of preload I’ve ever seen":
