Description

man page:

allow booting; deny booting; ignore booting;
The booting flag is used to tell dhcpd whether or not to respond to queries from a particular client. This keyword only has meaning when it appears in a host declaration. By default, booting is allowed, but if it is disabled for a particular client, then that client will not be able to get an address from the DHCP server.

authoritative;
The DHCP server will normally assume that the configuration information about a given network segment is not known to be correct and is not authoritative.
Network administrators setting up authoritative DHCP servers for their networks should always write authoritative; at the top of their configuration file to indicate that the DHCP server should send DHCPNAK messages to misconfigured clients.

update-static-leases on;
The update-static-leases flag, if enabled, causes the DHCP server to do DNS updates for clients even if those clients are being assigned their IP address using a fixed-address statement.

use-host-decl-names on;
If the use-host-decl-names parameter is true the name provided for the host declaration will be supplied to the client as its hostname.

Segnalo proposta per ulteriori impostazioni da mettere di default per server dhcp.

Dopo aver sentito anche Simone

authoritative sì, nessun problema, ha senso metterlo (non ci sono altri DHCP sulla rete, giusto?)

Per il resto, ci pare che abbiano senso solo nel caso in cui venga fatta configurazione lato server con dichiarazione di host, che al momento mi risulta non venga fatta, o sbaglio?

Questa configurazione però non arriva dal fuss-server, è una cosa custom della macchina? che macchina?

Di sicuro nel caso allow|deny|ignore booting; andrebbe messo in quel file, a seconda di come lo si vuole configurare.

Per gli altri due, ci sono dei casi d'uso per cambiare il default?

Intanto ho aggiunto authoritative nella versione che c'è sul repository, arriverà nel pacchetto assieme alle prossime modifiche.
