On a related note, since we can’t run our own instance of avahi-daemon anymore, is there any easy way to advertise new services via avahi?

I’ve been trying to create a new service via d-bus to the host avahi, but it seems like the whole `EntryGroup` interface of methods can’t be seen?

```bash
root@3aab805-3aab805:~# dbus-send \
> --system \
> --print-reply \
> --reply-timeout=2000 \
> --type=method_call \
> --dest=org.freedesktop.Avahi \
> / \
> org.freedesktop.Avahi.Server.EntryGroupNew
method return sender=:1.2 -> dest=:1.4 reply_serial=2
   object path "/Client0/EntryGroup1"

root@3aab805-3aab805:~# DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host/run/dbus/system_bus_socket \
> dbus-send \
> --system \
> --print-reply \
> --reply-timeout=2000 \
> --type=method_call \
> --dest=org.freedesktop.Avahi \
> /Client0/EntryGroup1 \
> org.freedesktop.Avahi.EntryGroup.AddService \
> int32:-1 int32:-1 uint32:0 string:'HTTP Service' string:'_http._tcp' string:'' string:'' uint16:80 array:byte:""
Error org.freedesktop.DBus.Error.UnknownObject: Method "AddService" with signature "iiussssqay" on interface "org.freedesktop.Avahi.EntryGroup" doesn't exist

```

I thought it might just be me getting the method argument types wrong, but even when calling one of the methods with only output arguments shows up as `doesn't exist`.

```bash
root@3aab805-3aab805:~# DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host/run/dbus/system_bus_socket \
> dbus-send \
> --system \
> --print-reply \
> --reply-timeout=2000 \
> --type=method_call \
> --dest=org.freedesktop.Avahi \
> /Client0/EntryGroup1 \
> org.freedesktop.Avahi.EntryGroup.GetState
Error org.freedesktop.DBus.Error.UnknownObject: Method "GetState" with signature "" on interface "org.freedesktop.Avahi.EntryGroup" doesn't exist

```

Anybody have any luck with this?
