Hi,

You=E2=80=99re probably correct - I was lead to that approach perhaps =
more
because the initramfs already does configure the eth0 interface =
correctly.
Adding /etc/network/interfaces and the networking service is probably
the better approach, yes. Feel free to disregard this patch.

I do wonder to what extent applications rely on lo to work without
explicitly needing networking as such, but if that hasn=E2=80=99t been =
an issue
until now, no reason to further dig into it.
