So that one can have roles that simply define attributes.
Setting the fix version to 0.8.0, as we should definitely include this.
actually, seems like you can create roles with nothing in the run list, but you can't then edit them.
http://github.com/thommay/chef/tree/CHEF-684-0.7 for 0.7; 0.8 to follow soon.
Can't reproduce in 0.8; guess if there's another 0.7 release it'd be nice to see a fix but besides that I think we're good.
Thanks, Thom. 0.8.0 is the next release, so we're good to go here.
