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, the config_version script just showed the commit ID of
the version of code being compiled. This commit includes the compiling
Puppet master's hostname and environment name in the config_version.
This is very useful for debugging when a Puppet master is failing and
you have multiple masters behind a load balancer.
The output of config_version now looks like this:
pupmaster01-production-ac9785273a10
Prior to this commit, if you used windows bash git when you clone
down the repo these files would get incorrect permissions which
make them unexecutable.
After this commit, due to some windows bash git magic I don't
understand it appears that adding the shebang to the beginning of
the file causes windows bash git to change the permissions to
so the file is executable.
This resolves https://github.com/puppetlabs/control-repo/issues/40
