#This guide is for Ubuntu 10.04 & 10.10; For other versions, please refer to the reference below.
#Reference: http://wiki.meego.com/Image_Creation
#1. Environment creation:
 1.1: sudo apt-get install yum rpm kpartx parted syslinux isomd5sum kvm zlib1g-dev squashfs-tools python2.6-dev qemu-arm-static python-urlgrabber

 1.2: add the below line to /etc/apt/sources.list
    For Ubuntu 10.04, add the below line to /etc/apt/sources.list 
      deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.04/ /

    For Ubuntu 10.10, add the below line to /etc/apt/sources.list 
      deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.10/ /

 1.3: Execute:
    sudo apt-get update
      [Should see some error "GPG error"]

 1.4: add the repository public key using the following command:
ssh-keygen -t rsa ;(If neccesary)
    gpg --keyserver subkeys.pgp.net --recv 0BC7BEC479FC1F8A 
    gpg --export --armor 0BC7BEC479FC1F8A | sudo apt-key add - 

 1.5: Again execute:
    sudo apt-get update

 1.6: Meego Image Creator (MIC2) Installation
    sudo apt-get install mic2 


#Building a MeeGo chroot on Linux
#Reference: http://wiki.meego.com/SDK/Docs/1.2/Building_a_MeeGo_chroot_on_Linux

#1. Prepare chroot image:
  1.1 Unpack the image using MIC2
    sudo mic-chroot --unpack-only -s ~/meego-chroot <image file>.img

#2. Chroot into the image using mic-chroot: 
    sudo mic-chroot ~/meego-chroot

#3. Environment creation (into chroot):
 3.1: #sudo zypper in yum rpm kpartx parted syslinux isomd5sum kvm zlib1g-dev squashfs-tools python2.6-dev qemu-arm-static python-urlgrabber osc build

 3.2: Install Perl from MeeGo repo:
      #rpm -ivh --nodeps --force ~/Downloads/MeeGo/snapshots/stable/1.2.0.90/1.2.0.90.3.20110607.2/repos/oss/ia32/packages/i586/perl-*.rpm
      #rpm -ivh --nodeps --force ~/Downloads/MeeGo/snapshots/stable/1.2.0.90/1.2.0.90.3.20110607.2/repos/oss/ia32/packages/noarch/perl-*.rpm
      #rpm -ivh --nodeps ~/Downloads/MeeGo/snapshots/stable/1.2.0.90/1.2.0.90.3.20110607.2/repos/oss/ia32/packages/i586/rpm-*.rpm
      #rpm -ivh --nodeps ~/Downloads/MeeGo/snapshots/stable/1.2.0.90/1.2.0.90.3.20110607.2/repos/oss/ia32/packages/noarch/rpm-*.rpm

 3.3: Add URL to yup repos:
#cat <<REPO > /etc/yum.repos.d/meego-tools.repo
[meego-tools]
name=MeeGo Tools for Fedora
baseurl=http://repo.meego.com/MeeGo/tools/repos/fedora/12
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-meego
REPO

 3.3.1
ssh-keygen -t rsa
 3.4: add the repository public key using the following command (before create SSH key):
    #gpg2 --keyserver subkeys.pgp.net --recv 0BC7BEC479FC1F8A
    #gpg2 --export --armor 0BC7BEC479FC1F8A > /etc/pki/rpm-gpg/RPM-GPG-KEY-meego

 3.5: Meego Image Creator (MIC2) Installation
    #yum install mic2

 if you get asked to import the key do so: 

    warning: rpmts_HdrFromFdno: Header V3 DSA/SHA1 Signature, key ID 79fc1f8a: NOKEY
    meego-fedora/gpgkey                                                                        | 3.3 kB     00:00 ...

    #yum update mic2

 3.7: Install MeeGo 1.2 config:
    Download \\runnfs003\LGE_Car\CM\Config\meego-1.2.conf to /usr/lib/build/configs
    #sudo ln -s -f /usr/lib/build/configs/meego-1.2.conf /usr/lib/build/configs/default.conf

 3.8: Exit from chroot:
    #exit



#4. Build chroot rpm:
