With the ethernet unplugged, installing with a netinst iso, I do get a
minimal installation. With ethernet plugged in, the installed kernel
can be booted repeatedly, presenting a login prompt each time. adduser,
mount, cat, lp... just work.

Now, I want to update and upgrade and start to slowly add packages, but
my network ignorance is getting in the way. 

Tried to run "/sbin/ifconfig -a" but ifconfig is not found. Anyway, ran:
  dhclient lo
  dhclient eth0
...with no effect (could not ping google)

Comparing files on this install with the same on this one (where I'm
writing this post):

/etc/network  # same contents on both after I added a link: 
    run -> /network
/etc/network/interfaces.d  # empty on both
/run/network  # same on both
/var/log/syslog  # doesn't show anything obvious to me

root@debm:/etc/network# cat interfaces
# This file describes...
# and how to ...

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

root@debm:/# /etc/init.d/networking stop
Stopping networking (via systemctl): networking.service.
root@debm:/# /etc/init.d/networking start
Starting networking (via systemctl): networking.service.
root@debm:/# ping -c 3 http://www.google.com
ping: http://www.google.com: Temporary failure in name resolution

Please point me to how to get ethernet up. Thanks.
