====Getting the Script====

  wget http://gaby.rohost.com/curtin-img-builder.tar.gz
  
  tar -xzvf curtin-img-builder.tar.gz
  cd curtin-img-builder/bin
  
  ls -l build    # our script


====Getting Prerequisites====

  # to be used on ubuntu with virtualization capabilities
  sudo tasksel # select virtual machine host
  
  # for any other prerequisites the script may require
  sudo ./build --install-deps


====Better Mirrors====

The default mirrors make 200 kbps seem dreamy; change them from this file if you're not getting any younger:

  curtin-image-builder/contrib/centos/centos7/centos7-amd64.ks   # lines 5 to 8

You can find CentOS mirrors [[http://www.centos.org/download/mirrors|here]].


====Usage====

  # basic usage example:
  sudo ./build --vcpus 2 -r 4096 -o /root/images --centos-edition 7 centos amd64


====Adding them to MaaS====

  # run as the MaaS user:
  maas root boot-resources create name=centos/7 architecture=amd64/generic filetype=ddtgz content@=/path/to/file
