Except, using Ironic to configure a node's hardware probably requires
rebooting that node -- and thus interrupting the workload that was
just deployed onto it, and possibly (if you're rebuilding a RAID)
destroying that instance. Clearly this doesn't make sense.

Yup. See my previous comments. Heat is not a generic "manipulate this
text file" hammer. That's Perl.
