[Bug 1301015] Re: Networking does not restart

[Matthew Walker]

Regardless of whether it's officially supported or not, the method did
solve a lot of problems in one command. The only times it has caused
issues for me is when I have tun devices created by other services. In
general, I feel a better solution would be to have the networking only
restart those adapters which it controls (seen in /etc/interfaces).

Can you point us to the discussion you had on a mailing list, or bug, or
otherwise where it was discussed that this change needed to be made?
Otherwise it seems like it was made by fiat and it's now 13 to 1
against.
