I've added the following file:

/etc/network/interfaces.d$ cat lo1.cfg
auto lo1
iface lo1 inet loopback

How do I get it to take effect if not `restart networking`? I've tried `ifup lo1` but it just says cannot find device lo1. I have a feeling that I did `restart networking` before on a pre-trusty box and it worked.
