However, that would mean that all the rhel/centos boxes would suddenly become 
dependent on the apt cookbook, even though they don't use apt.  The apt 
recipe might not be added to the run list, but the dependency would still be 
there.

Personally, I would create OS-specific roles & cookbooks for the stuff that 
needs to be os-specific (like depending on apt), and then include all the 
generic stuff that doesn't need to care what particular platform you're 
running on.
