Prior to 136b1aa646 it was possible to
have an empty string as value of a my.cnf parameter, resulting in a line
with just the parameter name.
That commit re-enable that behavior that was removed by accident.
Switching out the puppet version, as puppet_facts does, does not work,
as this will confuse code that wants to use version-dependent features.
Instead this uses rspec-puppet-facts, which doesn't touch the puppet
version.
Running RHEL 7.1, puppetlabs-mysql is not idempotent.
After a second run, puppet tries to change the SElinux context:
/File[mysql-config-file]/seltype: seltype changed 'etc_t' to
'mysqld_etc_t'
Since packaging already manages SElinux labels, we should not let
Puppet doing it (default behavior).
This patch aims to set selinux_ignore_defaults to True for the
mysql-config-file File resource.
Thanks to that patch, Puppet will be indempotent between all runs on
RHEL platforms.
