Hi, I'm not overly thrilled with having multi-tiered driver packages. That leads to major headaches when we start shuffling things around from one driver package to another. The current solution I have prototyped is a kernel-core/kernel-drivers split. Here core could be analogous to

Hi, Agree, I don't think it makes much sense to split things into many small pieces. - Do you need/want a firewall (requires iptables, etc)? I'd say yes by default, but being able to remove it might be useful (kernel-netfilter subpackage)? So you agree multi-tiered subpackages
