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.
Эта фича конфигурирует базовую поддержку сети, включая нужную подсистему (etcnet, NetworkManager поверх etcnet или connman).
