# Fedora Atomic is a cloud-focused spin implementing the Project
# Atomic patterns.  Note that this replicates the same tree which can
# now be installed on bare metal.

# This image allocates most space to an LVM-managed thin pool
# dedicated for Docker containers, and uses docker-storage-setup to
# dynamically resize storage on boot.
