# Fedora Atomic is a cloud-focused spin implementing the Project

# This image allocates most space to an LVM-managed thin pool

# dedicated for Docker containers, and uses docker-storage-setup to

# However, the disk size is currently just 6GB for the cloud image (defined in pungi-fedora). So the

# "15GB, rest unallocated" model doesn't make sense. The Vagrant box is 40GB (apparently a number of

# Vagrant boxes come big and rely on thin provisioning).
