Right.
Well, I am wondering how can client configurations be added/removed dynamically while the daemon is running and without causing a problem when many clients are involved.
First of all dhcp leases are not dependent upon maintaining a session with a dhcp server. The process of acquiring a lease, and later renewing it is a simple brief exchange between the client and server. And a client will attempt renewal several times before the lease expires, so a momentary failure should not cause the loss of a lease.
Because of this restarting a dhcp server is unlikely to impact anyone unless it serves a large number of clients with very short lease times.
By using the command:
service dhcpd restart
to restart the daemon it will include testing the configuration first, and not stopping and restarting unless the configuration is error free. This prevents a lengthier outage while you figure out your editing mistake.
