[systemd-devel] Need advice on daemon's architecture

'Twas brillig, and Peter Lemenkov at 03/11/13 06:40 did gyre and gimble:

If you are using systemd intensively, then you may want to use Type=notify.

With type=dbus, systemd will consider things ready when you take the
name on the bus, but this might not actually be the last thing you do to
initialise your daemon (although if this is the only interface for
clients this is not a problem!).

You still might want to use sd_notify() instead. This can also pass
through some internal performance info to systemd which will show up on
systemctl status output which is kinda nice.
