Accessing the metadata API?

[Blake Rouse]

Jim,

At the moment the best documentation we have for this is here:

https://maas.ubuntu.com/docs/configure.html#altering-the-preseed-file

We are working on improving the documentation for MAAS, but we have not add
that section yet as we are working through it. The updated documentation is
located here: https://docs.ubuntu.com/maas/2.1/en/ but does not document
the preseed possibilities.

There is a bug filed about this:
https://bugs.launchpad.net/maas/+bug/1334426 and I will raise it with our
documentation team to get it improved.

Thanks,
Blake
