# The cloud init script detects the EC2 instance platform at launch and uses preferred package manager
# AWS cloud init script to install ansible on startup, autodetects required package manager
# Add as user data inside advanced details at AWS EC2 configure instance details (step 3)
# Changes:
# Ver 2.1 Tested on Centos 6
# No issues with pynacl and cryptography
# Ver 2 Tested on RHEL, Centos 7, Ubuntu, SUSE, Fedora 23-25, Debian
# No issue with pycrypto (on Fedora)
# Install & Test
# Add as user data inside advanced details at AWS EC2 configure instance details (step 3)
