I don't understand the point of this. Why is this kind of emulation
helpful? Is this just to create honeypot? Or am I missing something.
Some additional information is also missing ... what privileges does the
faked run under? Who inserts the LD_PRELOAD into the environment? Is
this done using fakeroot(1) to execute the program?
It would be nice to have man pages handy without having to download the
source code to extract them.
Also, some of your exported interfaces are not declared with stability
levels.
