messages in the output, for both books. Not sure if this is a regression, but it seems that most of the links are still there and working, at least in the PDF format – I was able to generate all formats of both books from this branch. I will play-test them today. Thanks!

The updates are great! Both books are showing up with images properly included in the pages now, on mobi format. You have done a better job fixing this up than I was prepared to do. I will see if I can find out more about the apparently broken links, but I only found working links while I was browsing through the content myself, so apparently if there are broken links, it's only some of them.

The irony is also not lost on me that I am reading Google's SRE books on Amazon's reader device, ha ha...

@kingdonb Thanks for your comments :-)

This problem happens with old version too.
Honestly I didn't look into it since no much effect on the result.

@captn3m0 Thanks for the merging :-)

Thanks a lot @aabouzaid, this looks great 💯

Now that we have both books covered, I've created an issue to track typesetting or other reading issues: #22

Will take them up one by one, but feel free to add issues there.
