What services does your daemon provide?
?? Does it matter? It answers queries received over the network.
Will it rebind to network interfaces if they change?
Hmm. Can you be more specific? I have problem coming up with scenario where replacing of NIC or changing of MAC/IP address could be handled transparently to the clients.
Does it need to write to disk?
Does it need syslog to do logging output?
Does it matter? The typical configuration is to use direct logging to file. Without syslog. On Linux syslog may be used to log startup/shutdown of the daemon. Most likely using logger(1). On other platforms some native solution would be used.
If it crashes, should someone be notified? How? When? How often? Who?
If it crashes, people will notice because they don't get a service the daemon is providing. Immediately. They will notify the administrator and require the service to be restored. The administrator will capture the current logs and storage for investigation and restart the service. For HA systems, there will be failover system.
