Working with Kickstart

* Remove config options for:
  osdir
  sourcedir
  debugdir
  isodir
  iso_basename
  cachedir
  arch
  relnotefilere
  relnotedirre
  relnotepkgs

DONE ^^

* Move to CLI only:
  name
  version
  destdir
  flavor (optional)
  bugurl (optional)
  discs (optional)
  nosource (optional/debug)

DONE ^^

* Make the following transitions
  product_name -> name
  product path == 'Packages/"
  get comps data from repos
  cachedir == /var/cache/pungi ?

* From pykickstart
  manifest -> %packages
  yum-repos -> repo
  isosize -> part iso size <size> (optional)

* Release notes stuff
  Drop all stuff but GPL, README, GPG keys, potentially README-BURNING-ISOS ?

* fedora-release
  Provides: system-release = %{version}-%{release}

* Profit!
