avahi-daemon not startable

Hi,
i need avahi-browse inside of Fhem Docker.
So i need to install those packets:
`apt-get install -y avahi-utils avahi-daemon libnss-mdns systemd`

My Dockerfile:

FROM fhem/fhem:bullseye


RUN apt-get update -y &&  \

    apt-get upgrade -y && \

    apt-get install -y avahi-utils avahi-daemon libnss-mdns systemd && \

    apt-get clean && \

    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

My docker compose file:

  fhem:

    build:

      context: fhem

    image: fhem:1.0

    container_name: fhem

    hostname: fhem

    volumes:

      - fhem:/opt/fhem

      - /var/run/dbus:/var/run/dbus

    ports:

      - 8083:8083

      - 7072:7072

    restart: unless-stopped

After starting the docker the daemon didn´t start:

root@fhem:/tmp# avahi-browse -a

Failed to create client object: Daemon not running

So I have to do the following steps for a proper working inside of docker:

rm /run/dbus/pid

dbus-daemon --system

/etc/init.d/avahi-daemon start

avahi-browse -a

[.....]

Its a problem inside of the fhem docker why dbus is not startable?
If not, how can i add a custom startscript to execute the needed steps after each container start?
