Well done that man
May I suggest that you take some of Tutorial 6 and try to work it in a bit earlier in the series? I think it would read a bit better if permissions (passwords) and filesystems/mount points were somewhere nearer tutorial 2 where you do mention root passwords.
I still remember the trepidation of installing new operating systems and thinking "Oh gods where's the hard drive gone", then thinking "Great the manual is on the CD which has gone where exactly.....?"
Can't really think of much else to say as it seems spot on
PS - I'm assuming the Tutorials are still open to edits? I think once you get it polished
just right (in your eyes) you should take all the Tutorials and use OpenOffice to turn it into a nice PDF suitable for download. Its not that many pages so it seems just about right for printing before that install
