Interesting. That's worked for me in the past. Well outside of
creating a package resource default, you'll need to just put requires
in the classes that require other classes to be run first. Really,
that's not a bad idea at all since relationships should be explicit
if not just for readability. Remember that puppet should be your
executable documentation.
You might be able to do something like:
if defined(Class["yum"]) {
require yum
}
But I've never tried that. If it works, then it will only define a
relationship if the class is actually being used. Just keep that this
will not work in 0.25 since require is broken. It will work in 0.25.1
though.
