Hi,


"network usable" might be significantly later, and your services usually
should not wait for such an event.
See http://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/

You would also not sort services that require NetworkManagers DBUS API
"After=NetworkManager". Hence they wouldn't have to wait full 580ms but
instead start in parallel and block until NetworkManager being ready to
answer requests on DBUS.


So neither of this ~should~ delay your boot, but checking with
systemd-analyze might be interesting.
