=== DHCP Hostname Priority

ifdef::topdoc[:imagesdir: {topdoc}../../test/case/dhcp/client_hostname]

==== Description

Verify deterministic hostname management: a DHCP acquired hostname takes
precedence over a configured hostname.  When a DHCP lease ends, or the
hostname option is removed, the system should revert to the configured
hostname.
