network setup failed with small subnet

[Jeff Lane ]

Doing setup within a customer environment. We have been given a very small subnet:

172.29.160.96/27

and during setup via maniacs-setup, this was what happened when setting up the subnets and dhcp:
***************************************************************************
* Your internal network has too few addresses; please specify the values
* for two IP address ranges: reserved (never used by MAAS) and DHCP
* (used by MAAS with DHCP). Note that a third range is implicit -- those
* in the network block but not specified in these two ranges. This third
* range is used by MAAS for auto-assigned static addresses.
*
* Low IP address for reserved addresses: 172.60.129.110
* High IP address for reserved addresses: 172.60.129.126
* Low IP address for DHCP addresses: 172.60.129.97
* High IP address for DHCP addresses: 172.60.129.109
* Setting up MAAS IP address ranges:
* Low reserved IP address = 172.60.129.110
* High reserved IP address = 172.60.129.126
* Low DHCP IP address = 172.60.129.97
* High DHCP IP address = 172.60.129.109
* Low auto-assign IP address (implicit) =
* High auto-assign IP address (implicit) =
* Initializing rack controller

However, once logged into the MAAS UI, none of those ranges had been set up, and DHCP was not active. I had to manually configure them in the UI and then activate DHCP.
