the configration information came from.

may result in the route command returning non-zero which produces
some confusing output for users manually using ifup/ifdown[1]. To
that end, we will optionally include an '|| true' postfix to each
route line allowing users to work with ifup/ifdown without using
--force option.
We may at somepoint not want to emit this additional postfix, and
add a 'strict' flag to this function. When called with strict=True,
then we will not append the postfix.
