DHCP clients can send specific values in the dhcp request such as hostname, lease time, client_id, vendor_id, etc.

The dhcp configuration option in v1, and v2 (and others) only has dhcp as a boolean.

v1:
network:
version: 1
config:
- type: physical
name: eth0
mac_address: 00:11:22:33:44:55
subnets:
- type: dhcp
hostname: myhostname
client: client_id_1
lease: 3600

Would render in eni:

auto iface eth0 dhcp
hostname myhostname
client: client_id_1
lease 3600
