I know this is nitpicky but I still thought it may be useful information. I think that noautomount was misspelled on Exercise 3 of Chapter 2. The text is as follows: "(...)While noswap is a standard Debian boot parameter, the noautomaount is a Kali specific feature(...)".
Insert image doesn't appear to be working from my end but then again that is just in the preview so I am curious how this message will come out.
