My reply was to the answer "Not on production. Only for testing.".
I didn't go into detail because I thought it's obvious that it's not so
easy. I didn't mean to blindly feed all CR updates to production
environments. In fact over here, we never ever feed any update directly
from public servers to any production machine. It all comes from local
repositories where we have control over what goes where and we can make
sure not to blindly make updates.
What I meant is that just staying away from CR for production servers
sounds dangerous. You just can't if security critical updates are only
available in CR.

Simon
