This commit moves the "where did all the previous code go" section to
the bottom as it's been a while since that change was made. Nowadays,
people new to Control Repositories will find this and won't understand
the reference as they never knew about previous versions.
Now the README starts right away with information on what this project
is and how to use it.
Also cleaned up some of the Markdown syntax to make it easier to read.
This is mainly a style and readability change.
Prior to this, on masters whose hostname is actually their FQDN, the
config_version script would show the entire FQDN. On nodes with really
longs FQDN's, it was not very nice to look at.
This takes the hostname of the master, splits it on dots (.) and takes
the first segment.
Now this: compile-master-02.int.lab.dmz.company-name.net-production-48fd18ab
Is this: compile-master-02-production-48fd18ab
Prior to this, the config_version.rb script (used for r10k) attempted to
use the system ruby to parse the script. This caused problems on Puppet
masters that don't have `ruby` in PATH.
This fixes that by hardcoding the puppet-agent's ruby in the shebang.
Prior to this, modules that were deployed with r10k into the ./modules
directory weren't being ignored by git.
When doing local development or testing, it's nice to be able to run
'r10k puppetfile install' to pull down modules from the Puppetfile.
After this commit, those modules won't be tracked by git.
