test it out. Unfortunately I really do need the puppet support I don't want
to distribute my own puppet and augeas RPM's so I'll have to wait until
Puppet is updated and EPEL has pulled everything in. But I can write out the
basic puppet for my modules and just not have the directory edits called
until they're supported. Thanks to both you and Frederik for helping with
this.
