Bug Description
Shows up in version 18.04 of Ubuntu.
I added the following 2 lines in /etc/sysctl.
```
net.ipv6.
net.ipv6.
```
Rebooting my machine sets those parameters for "all" and "default" but not for
the sysctl options of my network interface:
```
net.ipv6.
net.ipv6.
net.ipv6.
```
I use disable_ipv6 above as an example.
I've also verified this with the promote_secondaries option of ipv4.
I can always restart systemd-
set net.ipv6.
work for devices that are hot-plugged.
Other info:
- version signature: Ubuntu 4.15.0-
- lspci is attached
