Well, to address that we can create a "master-list" of gentuid/gentgid's a-la 
/etc/services. When a package needs user/group it consults these lists in 
order to pick "proper" id.
But then is there any security implication in doing it this way or otherwise? 
If somehow security can be enhanced by keeping u/gids's random this may be 
made optional and even with option to randomize u/gid's more..
