After first thinking that the former patch was a good idea, seeing this
now I agree with Sascha this new approach is better.

Maybe add the following (in a separate commit?):

diff --git a/defaultenv/defaultenv-2-base/network/eth0 b/defaultenv/defaultenv-2-base/network/eth0
index 33fe7c1b2b48..992e37a35deb 100644

 # MAC address if needed

+# one network adapter)

 exit 0

Other than that:
