Thanks for the series, looks like a sweet cleanup. The tool has been
needing some cleanup for some time.
As far as I can tell you haven't changed the fundamental way it
reads/writes (in fact you've forced the use of MTD which is a good
thing). The reason I ask this is that I'm getting increasingly keen on
an OPAL call to get gard records/partitions (details to be worked out),
think the way we currently do NVRAM. I can't see any reason why your
improvements make a transition to an OPAL call to get data harder but I
thought I'd ask.

Is there any way we detect a default programatically?

As long as you're happy to deal with the fallout when people discover
this (record creation) is a thing and start doing dumb things with it
then thumbs up!
