[OE-core] loopback interface not brought up on 'ifup -a' automatically

[Daniel Ceusan]

Hi,

I am building an image using rocko branch and installing ifupdown package:
http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-core/ifupdown/ifupdown_0.8.16.bb?h=rocko

If there is no loopback definition in /etc/network/interfaces file, then "ifup -a" brings lo interface up automatically.

If I define the lo interface:
"auto lo
iface lo inet loopback"
then lo interface is not brought up automatically by "ifup -a", even though from ifupdown's changelog/documentation it says both approaches should work.

Anyone else seen this behavior?

Thanks and regards,
Daniel
