It could be a good idea, but I'm looking for a way to do it from the server.
I mean, that way I would have to modify my nodes' chef-client config 
every time I'd like to add something new to the "default run list" 
instead of just having it automatically replicated on every new node. 
This seems pretty unmaintenable for me.

I'm thinking about running "chef-client -j" to add a default run list 
with only one recipe that retrieve the real "default run list" from, for 
example, a databag in the server.
It still sounds hacky to me, but at least I wouldn't have to modify my 
nodes' chef-client config every time manually, just once.

I think I'll look into chef-server's code to see if I can "plug" the 
default run list somewhere.
