I think it's great you've shared this. With the recent SIP changes, thousands of Stack Overflow guides that involve "running a few commands with sudo" are now potentially broken. If devs/users are unfamiliar with this change, they might follow an out-of-date guide and become stuck for hours. It almost happened to me last week when I tried following a stack overflow post to fix some symlink issues with /usr/bin/. Fortunately I read about SIP previously on HN and was able to work around it. But I'm worried for the thousands of other devs that haven't heard of or encountered SIP. There needs to be more awareness of this change because it affects much more than people expect.
Takeaway: if you're following a OS X guide that involves sudo written before 10.11, keep SIP in mind or you might get burned.
