Shouldn't DISTRO's decide on a per DISTRO decision whether or not their 
preferred versions are weak?

I;m not entirely opposed to make the assignment weak for Angstrom, but I 
am very opposed to making all DISTRO's use the same policy.

It is a real nuisance trying to debug someone's Angstrom build, only to 
fins out they have loads of local overrides.
