Yun user setup

Instructions for initial configuration of the Arduino can be found on the Arduino website
http://arduino.cc/en/Guide/ArduinoYun 

Once initial configuration is complete, SSH provides console access.  

The following packages installations are suggested to ease user interaction with Linino.

Nano - screen based text editor
openssh-sftp-server - provides access by sftp based client tools, such as TextWrangler and Cyberduck
rsync - provides command line ssh based file and folder transfer  

To install the packages type the following commands
opkg update
opkg install nano
opkg install openssh-sftp-server
opkg install rsync

Later versions of the OSX terminal application may fail to start Nano, due to the terminal being declared as xterm-256color.  Use the following command to fix the issue
export TERM='xterm-color'

The fix can be made permanent by creating a .profile file.  It may also be useful to alias ls to default to a wide listing which includes hidden files.

nano ~/.profile
export TERM='xterm-color'
alias ls='ls -hla'
