Hi Alan,

Here's some of the reasons i can think of why having support for multiple
interfaces would be useful:

- Not everybody is using configuration management tools (eg. small
environments)
- Configuration management integration is rather weak (atm just Puppet)
- It could be that pxe/install interface is physically separated from
management (eg. Puppet) and/or production interfaces (eg. due to security
policy)
- Managing machine specific data with configuration management tools might
not be that easy (eg. Puppet before Hiera got introduced)

Hope this helps!

Cheers,
Jörgen
