Changing default command prompt and mounting fat32 in read/write mode.

[Jeffery Mewtamer]

Best I can tell, my /etc/rc.local doesn't contain a existing PS1 definition, and apparently adding such a definition is more complicated than adding the line: PS1=$ on a blank line within the file. I'm no stranger to editing config files manually, but in this case, I am ignorant on how to edit the needed files to recieve the desired result.
