This is done so that it's easy spot large packages that are not
necessary and identify packages that have grown in size too much
by diffing the image compose logs.

# This is a Fedora 21 spin designed based on the Fedora Cloud Base Image
|
|
# but tailored specifically for Big Data processing out-of-the-box.
|
|
# Primarily, it builds on that image but adds extra packages, but over
|
|
# time may have additional focus.
|
|
#
|
|
# It's configured with cloud-init so it will take advantage of
|
|
# ec2-compatible metadata services for provisioning ssh keys. Cloud-init
|
|
# creates a user account named "fedora" with passwordless sudo access. The
|
|
# root password is empty and locked by default.
|
|
#
|
|
# Note that unlike the standard F20 install, this image has /tmp on disk
|
|
# rather than in tmpfs, since memory is usually at a premium.
