同学们在学习puppet时，一定发现有些博文中的命令在自己运行时没有。
下面，就送上2.6前后版本的命令对照。以供参考。
Single binary
From version 2.6.0 and onwards all the Puppet functions are also available via a single Puppetbinary, in the style of git.
List of binary changes:
puppetmasterd → puppet
masterpuppetd → puppet agent
puppet → puppet apply
puppetca → puppet cert
ralsh → puppet resource
puppetrun → puppet kick
puppetqd → puppet queue
filebucket → puppet filebucket
puppetdoc → puppet doc
pi → puppet describe
