We silently tolerate NetworkManager not responding at all (easily
reproduced with e.g. pkill -STOP NetworkManager):

As a comment in _dbus_get_managed_objects_cb() explains, this is sort of
intentional. NetworkManager might just be shutting down and the libnm
users will eventually see the objects once a new daemon starts up.
This may make some sense for long-running clients ("nmcli monitor",
various desktop environments), but not for one-shot invocations that
require the daemon running, such as those of "nmcli c ...".
Let's not consider the client running unless we actually got the manager
object. That way the error message will make more sense:

libnm-client-impl
libnm is NetworkManager's client API. This API consists of two parts:
- the handling of connections (
NMConnection), implemented by libnm-core-impl. - the caching of D-Bus API (
NMClient), implemented by libnm-client-impl.
This directory contains the implementation of the second part. As such, it will be statically linked with libnm-core-impl to make libnm. Also, it cannot be used by the daemon.
