as it is /bin/false on many systems but /usr/bin/false on OS X
test/playbook1.yml now just does command true, rather than command /bin/true,
again so that it works on OS X
Changed from using which false to just using command false to
make it simpler and also match how playbook1.yml works
refactoring of playbooks now warranted, which we'll do before we move on. This variable assignment
system makes nearly all possible magic possible, for we can use these variables however we like,
even as module names!
