Explaining weird solutions with cute explanations is cute.

You may not like the approach, but, please, stop using "infantilization" argument. Not all comic books and animated movies are for kids, even though they look like it might be the case. Here, it may open the subject for broader audience. It is easier to comprehend even for a layman. And even if you're not the one, you could dig in - just for fun. A picture is worth a thousand words, they say.
While I do enjoy some comic book and/or tv shows I did find this book a bit infantilizing. This looks more like Teletubbies than Rick and Morty if you see what I mean.
"Hey, I've heard you're too much of a dumb-dumb to get SELinux to work? Maybe if we turn it into an episode of Dora the Explorer you'll get it this time! Don't forget to renew your RHEL subscription by the way."

#23SELinux always makes me feel like I'm a complete idiot (the worst thing about that is that I could be an idiot and not know it or refuse to acknowledge it). So, maybe this introduction will make it a little more accessible.
If you're having issues with selinux run: sealert -a /var/log/audit/audit.log Most of the time, that will give you a detailed description of what's going wrong and tell you the command to fix it. Completely changed my opinion on selinux when I learned it. Also, the SELinux For Mere Mortals[1] talk is a great introduction. [1] https://www.youtube.com/watch?v=MxjenQ31b70&t=1s
It's nice... but the suggestions are often terrible when they could be fixed properly with a bool or changing the context of a directory.
I sat the RHCE course/exam recently and the Red Hat trainer dealt with this in... amusing... ways.
Unfortunately, fixing things properly requires knowledge, if only of where to find the information. Thinking solely about file contexts, it's not easy to for example search them. e.g. "show me all contexts related to samba" so you can find the share rw label. (One of the RHEL 7.0 man pages suggests the nfs rw label which doesn't work, had to make a point of remembering that for the exam!) Everything's spread across selinux's man pages, service's man pages... ugh.

#25I just wish I had some example commands to color in.

#26The thing that made SELinux click for me was this talk - it's really a great talk for SELinux: https://www.youtube.com/watch?v=MxjenQ31b70
(I also have a video explaining some specific/common things: https://serversforhackers.com/video/battling-selinux-cast)

#27This trend of using illustration to explain complex topics is really wonderful. I know that people may criticize it as childish, but I find it helpful and enlightening.
The illustrations that I've found most amazing and well done are created by people like:
Lin Clark (https://code-cartoons.com/)
Julia Evans (http://jvns.ca/zines/)
Linda Liukas (http://www.helloruby.com/)
Amy Wibowo (https://shop.bubblesort.io/)
You may notice a trend with the gender of the authors above. I personally believe that women have a better sense for simplifying complex ideas, and greater empathy and patience for teaching those ideas once they've been made simple.

Such comments made me do a new submission on the original motivation and architecture for it so things might make a bit more sense. At least explain why it's so complex.

#30Wow, I glanced through it in 5 seconds. I am sure kids will love it. But it is just hard for me to read it carefully. Maybe I am just too old.
