Please send this as Git patch, i.e. with a commit message. This is most easily done, by using git send-email. Write something in the commit message that explains the change, e.g.: Network configuration on sandbox requires some extra steps on the host OS. Document these. And don't forget your Signed-off-by. You should also mark the patch as v2 (pass -v2 to git send-email if you use that).

Do you do do these steps while sandbox is running?
