[Bug 1301015] Re: Networking does not restart

[Asher Newcomer]

Is there really no better solution for this than ifdown/ifup ?

What is the recommended method to restart all networking services,
rather than a select interface?

RHEL can manage this easily: https://access.redhat.com/documentation/en-
US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-
NetworkManager_and_the_Network_Scripts.html

"Although NetworkManager provides the default networking service, Red
Hat developers have worked hard to ensure that scripts and
NetworkManager cooperate with each other. Administrators who are used to
the scripts can certainly continue to use them. We expect both systems
to be able to run in parallel and work well together. It is expected
that most user shell scripts from previous releases will still work. Red
Hat recommends that you test them first."

What is the equivalent for Ubuntu / Canonical?
