I believe too many services depend on ‘networking’ for no good reason. There’s a good discussion of the problem at:
https://systemd.io/NETWORK_ONLINE/ For example, bitlbee, ntpd, hurd-vm, and avahi-daemon all depend on ‘networking’. Is it always justified? For example, avahi-daemon unconditionally listens on 0.0.0.0 and [::], so there’s no need to depend on ‘networking’. --8<---------------cut here---------------start------------->8--- $ sudo netstat -tupla |grep avahi udp 0 0 0.0.0.0:mdns 0.0.0.0:* 650/avahi-daemon: r udp6 0 0 [::]:mdns [::]:* 650/avahi-daemon: r --8<---------------cut here---------------end--------------->8--- In other cases, such as bitlbee, it’s not as obvious because users can specify different addresses to listen to, and those might depend on ‘networking’ to set up the corresponding interfaces. Thoughts? Should we do an audit of these? Ludo’.
