Renaming home folder

[Arwen]

As a test, I tried this whole process again.  I am pretty certain the wiki is wrong.

I downloaded the image from here:  https://github.com/mrfixit2001/debian_de...123.img.xz

I used Etcher to write the image to an SD Card.  
I booted and ran update script. 
I logged out of rock.
I logged into root
I opened the root terminal window and ran "usermod -l myNewUserName rock" and had no issues
I ran "usermod -d /home/rock -m myNewUserName"  and got the error -> usermod: no changes

Yes, that is wrong. It's basically saying change my home directory to the same name, then move my home to that location. Thus, no changes.

I've corrected it.

We sort of have the information in 2 places, the second, (which I started), has more details. Eventually we will decide which is better placement.
