Hi
My thoughts:
Shoe-horning the ephemeral partition into Cinder seems like a lot of pain for
almost no gain[1]. The only gain I can think of would be that we could bring a
node down, boot it into a special ramdisk that exposes the volume to the
network, so cindery operations (e.g. migration)

For decom (now zapping), I'm building it with config flags to either
disable it entirely, or just disable the erase_disks steps. No comment on
the daft bit :) But I do understand why you'd want to do it this way.

The problem with considering it a cinder volume rather than a nova
ephemeral volume is that it is just as leaky a set of semantics -
cinder volumes can be detached, attached elsewhere, snapshotted,
backed up, etc - a directly connected bare metal drive will be able to
do none of these things.
Each summit since we created preserve ephemeral mode in Nova, I have
some conversations where at least one person's brain breaks for a
second. There isn't always alcohol involved before, there almost
certainly is always a drink needed after. The very term is vexing, and I
think we have done
