Everything checks out correctly:

jashur@jashur:~/lab/chromeos-admin$ sudo python utils/presubmit_hooks/validate_dhcpd_conf.py
dhcpd.conf is verified successfully for chromeos-ddns1.mtv.corp.google.com-failover.conf.
dhcpd.conf is verified successfully for chromeos-ddns2.cbf.corp.google.com-failover.conf.

But I'm receiving the following unexpected output error when running the Hook script:

jashur@jashur:~/lab/chromeos-admin/puppet/modules/lab/files/dhcp-server$ repo upload .
Run hook scripts from https://chrome-internal.googlesource.com/chromeos/manifest-internal.git (yes/always/NO)? yes
