# This is a basic Fedora 20 spin designed to work in OpenStack and other
|
||||
# private cloud environments. 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.
|
||||
#
|
||||
# This kickstart file is designed to be used with appliance-creator and
|
||||
# may need slight modification for use with actual anaconda or other tools.
|
||||
# We intend to target anaconda-in-a-vm style image building for F20.
