That's true. Another reason it's useful if for livecd creators that
don't want to spend time compressing the image. So I added an option for
this along with other enhancements.

so now you can do things as shown in [1]. From a warm cache, the minimal
live cd now builds in around 2 minutes if you use --skip-compression and
local repositories. That's pretty nice.

 Examples:

  Create minimal live cd:
  # livecd-creator --config=/usr/share/livecd-tools/livecd-fedora-minimal.ks

  Create minimal live cd and use local package repositories:
  # livecd-creator --config=/usr/share/livecd-tools/livecd-fedora-minimal.ks \
                   --repo=a-dev,file:///home/user/core/RPMS             \
                   --repo=a-extras-dev,file:///home/user/extras/RPMS
