Yes,
a start job is running for LSB: Raise network interfaces. (xx / no limits)
xx is the timer running up.


Here it hangs. Forever.
Minimal install means in this case during tasksel I only selected "laptop"
nothing else.

However since yesterday I got my hands on an old macbook pro and I
installed debian on it. So this time during tasksel i left everything
preselectet (GNOME, print server, laptop IIRC).

Now I entered the lines for eth0 into the /etc/network/interfaces.
I unplugged the network cable and...

same line "A start job.." however this time it times out ( around 1min 30s)
which seems normal since 90s is the usual dhcp timeout.

I am scratching my head...
