Currently the varlink interface for hostname is only available
after sysinit. This means it is not available until systemd-firstboot
is finished. But there is information like the boot-id in there that
is useful to get early.
My use-case is to query the system early via the varlink-http-bridge
and currently I can't get data from io.systemd.Hostname until
systemd-firstboot is completed which is a bit limiting.
So to fix it this commit sets DefaultDependencies=no on both the socket
and service units.
It also changes hostnamed.c to use
bus_open_system_watch_bind_with_description() which means we will
reconnect once dbus is available. This mimics what resolved-bus.c
is doing (and which was originally introduced in d7afd945b).
Thanks to Lennart for pointing this out.
