The system is a standard Debian testing with minimal work to get Backuppc
and Samba running, no manual changes to networking stuff.
/etc/rcS.d/S40networking is there and looks fine,
same for /etc/network/interfaces:


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

I checked, it starts up with loopback only (after ifdown eth0).

juergen at piano:~$ grep interfaces /etc/samba/smb.conf
	interfaces = 127.0.0.1/8, 10.158.2.0/24
	bind interfaces only = Yes


This seems to be a spurious problem, I just did three reboots,
the first two went well, it happened again on the third one.
