**

**  Moode OS Builder v2.4

**

**  Welcome to the automated process for creating the wonderful

**  custom Linux OS that runs moOde audio player.

**

**  1. You will need a Raspberry Pi running Raspbian with SSH

**  enabled and at least 2.5 GB free space on the boot SDCard.

**

**  2. The build can be written directly to the boot SDCard or

**  to a second USB-SDCard plugged into the Raspberry Pi.

**

**  WARNING: Raspbian Stretch Lite 2018-03-13 must be used if

**  building directly on the boot SDCard. It must be a fresh,

**  unmodified installation of Stretch Lite otherwise the build

**  results cannot be guaranteed.

**

**  Be sure to backup the SDCard used to boot your Pi!

**

****************************************************************



** Write OS build directly to the boot SDCard (y/n)? n



////////////////////////////////////////////////////////////////

// STEP 1 - Writing OS to second USB-SDCard

//

////////////////////////////////////////////////////////////////



** Check free disk space

** Do you have a backup of your boot SDCard (y/n)? y

** USB-SDCard device detection:



   Accurately detecting the USB SDCard drive first requires

   that all USB storage devices are unplugged from the Pi



** Are all USB storage devices unplugged (y/n)? y



   Now plug in the target USB SDCard drive



** Is target USB drive plugged in (y/n)? y

** USB drive detected on /dev/sda

** Partitions unmounted on /dev/sda

** Options configuration:



   There are only two build options that can be configured. The

   1st is Proxy Server. Set it to 'n' unless you are certain that

   your network requires proxied access to the Internet. The 2nd

   is WiFi connection. For maximum speed and reliability set this

   to 'n' and use an Ethernet connection for the Build.



** Option 1-2: use a proxy server for Internet access (y/n)? n

** Option 2-2: use a WiFi connection instead of Ethernet (y/n)? n

** Configuration complete:



The Builder has completed the configuration and is now ready

to proceed with building Moode OS.



** Proceed with build (y/n)? y

** Test Internet connection

** Download helper files

** Add options to properties file

** Load properties into env

** Download Rasbian Stretch Lite 2018-03-13-raspbian-stretch-lite.zip

****************************************************************

**

** Base OS created on second USB SDCard drive

**

** Remove the USB SDCard drive and use the SDCard to boot a Pi.

** The build will automatically continue at STEP 2 after boot.

** It can take around 1 hour to complete.

**

** The cmds mosbrief, moslog and moslast can be used to monitor

** the build via SSH. Connect to server moode, user pi, and

** password moodeaudio for SSH login.

** Save base OS image for additional builds (y/n)? n
