netsetgo cannot recreate default route

[marcosps]

If we run netsetgo into an existing container with a default route already set, the error below is returned:

ERROR - file exists

and exit code is 1. But if we remove the default route from inside the container, netsetgo runs without any message, returning 0 as exit code. The code in question calls netlink.RouteAdd: https://github.com/teddyking/netsetgo/blob/master/configurer/container.go#L47

In this case, should netsetgo recreate the default route, or just let it be without error if a default route already exists?

Thanks!

The intention for netsetgo is that it only gets run once when a container is first created, at which point there should be no default route, so I think it's ok to just let it error out if a route does already exist.

Fair enough, but I will try to add a more meaningful message :)

Ok, lets close this old bug :)
