# The problem is that an RPM package may have a dependency on the asterisk-11-repo RPM
# package itself. If you install the other package, it will also pull in the RPM package.
# That's a bit icky, to be sure, but it won't actually *break* anything.
#
# The repo package would be installed, which would drop in a .repo file, but only do
# that ONE time. The yumrepo provider would then overwrite it with the actual contents
# as defined in your manifest and then maintain those properties.
#
# This is exactly how it works when you install a package with sample configuration files
# and then manage the real configuration files with Puppet.
