> Any ideas how this compares with Kerrisk's The Linux Programming Interface?

Unluckily, I don't know, but comparing the Table of Contents for both books

I would claim that The Linux Programming Interface covers a broader range of topics, and I also think this book goes more in depth. On the other hand, System Programming in Linux seems to be more pedagogical, and is more targeted towards people who profit from doing exercises and programming projects to get their hands dirty.
