THIS IS AMAZING! I would have never imagined seeing something this useful being made in my life.

I wouldn't rely on it being safe, it makes a lot of assumptions that programs that do destructive things might violate.

It's actually quite simple. LD_PRELOAD can achieve a similar effect, if the software is using the typical syscall library.

I know exactly how it was done, I am just amazed that it was done. It's a great idea that I have never come up with, nor would I be able to.

Yes, it's a great idea.

A similar idea is used to trace what 'make install' does so that stuff can be uninstalled later - or made into a package (rpm, dpkg etc)

I forget what that tool is called.

Also similar in concept is the tup build system which monitors rule commands run to gain knowledge of additional dependencies.
