But at the same time as ifupdown gets loaded, keyfile should also get
loaded if I'm not mistaken.  At the time load_connections() gets called,
the command line/config file will have been parsed, and all plugins will
have been registered.

That doesn't make sense, because the keyfile plugin gets loaded at the
same time as the ifupdown plugin.  priv->plugins gets set up in
nm_sysconfig_settings_add_plugin(), which is called from
main.c::load_plugins(), which is called once after reading the config
file or command line.
