From my last tests, if we try to use dhclient in the preseed files to release the IPs after an enlistment/commission, the DHCP server will still keep the lease set to 'active' and not 'free' until the 10 min lease time expires. Regarding the "Observed" state: when the lease is released/expired, it's removed from the "Used" list via maas-dhcp-helper. But in the release case, the lease is still active in the DHCP server until the expiration time hits, rendering it unusable for other machines until then.

So, in short, a lease can't be re-used until it expires (10 mins).

Is it possible to shorten this time by reducing the timeout or forcing the server to release the IP?
