No, because this only determines that the network-manager daemon is started
before those services that require a network; it says nothing about the
network connection being brought up.

It's a well-known issue to anyone trying to run network services on a
machine that uses network-manager.

However, in this *particular* case, the error is:

> in.tftpd[3590]: cannot resolve local IPv4 bind address: 0.0.0.0, Name or

So it's not as if we need a public network interface to be online; this
should work as soon as the loopback interface is up, which is already
guaranteed by the dep on $network.  If that's not working, this seems to be
a problem somewhere in the resolver config or in in.tftpd's handling of
numeric addresses (why does it try to resolve this address before binding to
it?)

So I don't think this is a general bug with NetworkManager at all, I think
it's a bug with tftpd mishandling numeric addresses that prevents it from
starting up in the absence of working DNS.
