live, net: shift and rework network and resolver setup 50-setup-network was a hasty hack (surprise!) that used to do what net and net-eth features have been created to do since; just drop the duplicated crufty code. Unconditional resolver setup isn't done now: those with static setup are better off doing it explicitly, and those with DHCP should be fine already. NB: /etc/hosts is fine within setup package but hasher will overwrite it with a copy of host's one; let's reset contents to initial at least until hasher gets fixed and the fix is rather deployed in the wild. 2014-03-14 18:21:40 +04:00			`#!/bin/sh`
net, net-dns: don't spam lo iface Putting any configuration into /etc/net/ifaces/lo/resolv.conf makes etcnet overwrite /etc/resolv.conf, while putting that into /etc/resolv.conf itself makes e.g. vzctl --nameserver append to what's been specified.
